Acid (noun, "AAH-sid")

This is any chemical that, when placed in a solution, releases hydrogen ions - atoms with a tiny positive electric charge. The charges make these ions react with bases, which are ions of another type. (Known as hydroxyl ions, those other ions have a negative electric charge.) Acids can eat away at many substances and tend to taste sour. When measured on a pH scale - a zero to 14 ranking of how acidic or basic chemicals are - acids measure below 7.0. And the lower the pH, the stronger - more powerful - the acid.

acid A chemical that releases hydrogen ions when dissolved in a solution. Acids have a sour taste and have a pH ranking of less than 7.0.

acidic An adjective for materials that contain acid. These materials often are capable of eating away at some minerals such as carbonate, or preventing their formation in the first place.

base (in chemistry) A chemical that produces hydroxide ions (OH-) in a solution. Basic solutions are also referred to as alkaline. (in genetics) A shortened version of the term nucleobase. These bases are building blocks of DNA and RNA molecules.

hydrogen The lightest element in the universe. As a gas, it is colorless, odorless and highly flammable. It's an integral part of many fuels, fats and chemicals that make up living tissues.

hydroxyl A chemical group, or pairing. It's made from an oxygen atom bound to a hydrogen atom, OH. In bases, it is negatively charged.

ion An atom or molecule with an electric charge due to the loss or gain of one or more electrons.

pH A measure of a solution's acidity. A pH of 7 is perfectly neutral. Acids have a pH lower than 7; the farther from 7, the stronger the acid. Alkaline solutions, called bases, have a pH higher than 7; again, the farther above 7, the stronger the base.

Savanna (noun, "Suh-van-uh")

If you've ever seen The Lion King, you've seen a savanna. A savanna is a rolling grassland scattered with trees and shrubs. This type of ecosystem covers about 20 percent of the world's land. That includes nearly half of Africa. The African savanna is home to lions, hyenas, zebras and other Lion King creatures. The Australian savanna hosts animals like kangaroos and wallabies. Savannas are also found in South America and Asia. And in North America, the oak savanna is one of the world's most endangered ecosystems.

Steepcone/Wikimedia Commons (CC BY-SA 3.0)

Most savannas don't have the four seasons you might be familiar with. These areas alternate between dry winters and wet summers. During the winter, a savanna may not get rain for months at a time. That prevents many trees from growing there. Dry conditions also allow savannas to catch fire easily. Those fires prevent young trees from growing up and turning these habitats into forests. But heavy summer rains help thick grasses grow. That prevents the savanna from being a desert.

Galaxy (noun, "GAAH-lex-ee")

This word describes an enormous collection of stars bound together by gravity. Galaxies typically contain millions to trillions of stars, plus gas, dust and leftovers from star explosions. Scientists estimate that there are at least two trillion galaxies in the part of the universe that can be observed from Earth.

Galaxies come in lots of different shapes. Our home galaxy, the Milky Way, is a spiral galaxy. These galaxies often look like pinwheels. Elliptical galaxies are fuzzy ovals. Some galaxies are called "irregular" because they lack symmetry and can look like a bunch of blobs. Gravity also pulls galaxies together into groups called clusters. These clusters can include just a couple of galaxies or up to thousands. Really big clusters can be tens of millions of light years across or even larger.

In some galaxies, new stars continue to form. Other galaxies have settled down and haven't seen a new star for billions of years. At the center of many galaxies are black holes, where gravity is so strong that not even light can escape. Earlier this year, scientists got a picture of a supermassive black hole in the center of the M87 galaxy. The M87 galaxy is located in the constellation Virgo.

Avalanche (noun, "AV-uh-lanch")

An avalanche is any large mass of material that is tumbling downhill. But the word usually refers to snow cascading down a mountainside. A snow avalanche is triggered when snow high on a mountain is disturbed. Falling rocks and earthquakes can destabilize snow. People can also set off avalanches by walking or skiing in the wrong place at the wrong time. Sometimes people will use explosives to cause an avalanche before someone can accidentally set one off and get hurt.

As snow slides downhill, it picks up speed, snow and other debris. Smaller spills of powdery snow are called sluffs. More dangerous avalanches occur when huge slabs of snow break loose from a mountainside. The snow in an avalanche can plunge downward at hundreds of kilometers (miles) per hour. And if someone is buried, it can be nearly impossible to dig out without help. An average of 27 people in the United States alone die in avalanches each year.

The most dangerous avalanches, called dry slab avalanches, occur when a very cold and dry snowpack is disturbed.

algae: Single-celled organisms, once considered plants (they aren't). As aquatic organisms, they grow in water. Like green plants, they depend on sunlight to make their food.

Arctic: A region that falls within the Arctic Circle. The edge of that circle is defined as the northernmost point at which the sun is visible on the northern winter solstice and the southernmost point at which the midnight sun can be seen on the northern summer solstice. The high Arctic is that most northerly third of this region. It's a region dominated by snow cover much of the year.

bdelloid: A class of rotifers (Bdelloidea) that exist solely as females. To reproduce, they clone themselves through a process known as parthenogenesis.

biologist: A scientist involved in the study of living things.

carbon dating: Short for radioactive-carbon dating or carbon-14 dating. A way to measure the age of organic materials - ones containing carbon. Carbon 14, a weakly radioactive isotope, forms in Earth's upper atmosphere as cosmic rays hit nitrogen atoms. This carbon joins with oxygen to form carbon dioxide, which living organisms take up and incorporate in their tissues. When those organisms die, they stop exchanging carbon with the environment and the share of the C14 isotope starts to fall at a constant rate (one set by the law of radioactive decay). By measuring the share of carbon-14 to carbon-12 in the organism's remains, scientists can determine how long ago it died.

climate change: Long-term, significant change in the climate of Earth. It can happen naturally or in response to human activities, including the burning of fossil fuels and clearing of forests.

clone: (in biology) An organism that has exactly the same genes as another, like identical twins. Often a clone, particularly among plants, has been created using the cell of an existing organism. Clone also is the term for making offspring that are genetically identical to some "parent" organism.

core: A long, tube-like sample drilled down into ice, soil or rock. Cores allow scientists to examine layers of sediment, dissolved chemicals, rock and fossils to see how the environment at one location changed through hundreds to thousands of years or more.

decay: (for radioactive materials) The process whereby a radioactive isotope - which means a physically unstable form of some element - sheds energy and subatomic particles. In time, this shedding will transform the unstable element into a slightly different but stable element. For instance, uranium-238 (which is a radioactive, or unstable, isotope) decays to radium-222 (also a radioactive isotope), which decays to radon-222 (also radioactive), which decays to polonium-210 (also radioactive), which decays to lead-206 - which is stable. No further decay occurs. The rates of decay from one isotope to another can range from timeframes of less than a second to billions of years.

embryo: The early stages of a developing organism, or animal with a backbone, consisting only one or a few cells. As an adjective, the term would be embryonic - and could be used to refer to the early stages or life of a system or technology.

microscope: An instrument used to view objects, like bacteria, or the single cells of plants or animals, that are too small to be visible to the unaided eye.

millennium: (plural: millennia) A unit of time equal to 1,000 years.

multicellular: Having or consisting of many cells. This includes all animals and plants, and many types of fungus.

organ: (in biology) Various parts of an organism that perform one or more particular functions. For instance, an ovary is an organ that makes eggs, the brain is an organ that makes sense of nerve signals and a plant's roots are organs that take in nutrients and moisture.

organism: Any living thing, from elephants and plants to bacteria and other types of single-celled life.

parthenogenesis: An unusual form of reproduction where animals sometimes produce healthy offspring from an unfertilized egg.

permafrost: Soil that remains frozen for at least two consecutive years. Such conditions typically occur in polar climates, where average annual temperatures remain close to or below freezing.

radioactive: An adjective that describes unstable elements, such as certain forms (isotopes) of uranium and plutonium. Such elements are said to be unstable because their nucleus sheds energy that is carried away by photons and/or and often one or more subatomic particles. This emission of energy is by a process known as radioactive decay.

radiocarbon dating: Short for radioactive-carbon dating or simply carbon dating. A way to measure the age of organic materials - ones containing carbon. Carbon-14, a weakly radioactive isotope, forms in Earth's upper atmosphere as cosmic rays hit nitrogen atoms. This carbon joins with oxygen to form carbon dioxide, which living organisms take up and incorporate in their tissues. When those organisms die, they stop exchanging carbon with the environment and the share of the C14 isotope starts to fall at a constant rate (one set by the law of radioactive decay). By measuring the share of C14 in the organism's remains, scientists can determine how long ago it died.

ratio: The relationship between two numbers or amounts. When written out, the numbers usually are separated by a colon, such as a 50:50. That would mean that for every 50 units of one thing (on the left) there would also be 50 units of another thing (represented by the number on the right).

rotifer: Any of the tiny (usually microscopic) invertebrate animals belonging to the class Rotifera. Most live in freshwater. They tend to have disk-type structures with powerful hairlike cilia that work like oars to move through water.

sediment: Material (such as stones and sand) deposited by water, wind or glaciers.

suspended animation: A temporary shutdown of most or all living functions without causing death. Examples can include a stored seed, hibernating animal or permafrost-trapped rotifer.

tissue: Made of cells, it is any of the distinct types of materials that make up animals, plants or fungi. Cells within a tissue work as a unit to perform a particular function in living organisms. Different organs of the human body, for instance, often are made from many different types of tissues.

unicellular: An adjective for organisms that possess a single cell, such as an amoeba or bacterium.

Ion (noun, "EYE-un")

An ion is an atom or molecule that has an electrical charge. The charge can be positive or negative. Atoms are made of protons, neutrons and electrons. The protons have a positive charge and the electrons have a negative charge. Neutrons have no charge at all. When there are equal numbers of protons and electrons, the charges cancel each other out. But when there are more protons than electrons, the molecule or atom will be an ion with a positive charge. When electrons outnumber the protons, the resulting ion is negatively charged.

Atoll (noun, "AT-all")

An atoll is a ring-shaped coral reef, island or chain of islands around a body of water called a lagoon. An atoll forms when an underwater volcano spills lava onto the seafloor. Over many eruptions, that volcanic rock piles up. Eventually, it rises above the water. This creates an island. Sea creatures called corals settle around the edges of that island. Their stony skeletons form a coral reef.

Over time, the central island erodes and sinks back down into the sea. Meanwhile, the coral reef remains. Over time, ocean waves break off bits of coral and grind them into sand. That sand builds up, along with other material swept in by wind and waves. This gives rise to a ring-shaped island, or smattering of islands, around the bowl of water, or lagoon, left by the sunken volcano.

erode: Gradual removal of soil or stone, caused by the flow of water or the movement of winds.

eruption: (in geoscience) The sudden bursting or spraying of hot material from deep inside a planet or moon and out through its surface. Volcanic eruptions on Earth usually send hot lava, hot gases or ash into the air and across surrounding land. In colder parts of the solar system, eruptions often involve liquid water spraying out through cracks in an icy crust. This happens on Enceladus, a moon of Saturn that is covered in ice.

lagoon: A small body of seawater - usually fairly shallow water - that's cut off from the open ocean by a sand bar, coral reef or narrow strip of land.

lava: Molten rock that comes up from the mantle, through Earth's crust, and out of a volcano.

marine: Having to do with the ocean world or environment.

reef: A ridge of rock, coral or sand. It rises up from the seafloor and may come to just above or just under the water's surface.

sea: An ocean (or region that is part of an ocean). Unlike lakes and streams, seawater - or ocean water - is salty.

volcano: A place on Earth's crust that opens, allowing magma and gases to spew out from underground reservoirs of molten material. The magma rises through a system of pipes or channels, sometimes spending time in chambers where it bubbles with gas and undergoes chemical transformations. This plumbing system can become more complex over time. This can result in a change, over time, to the chemical composition of the lava as well. The surface around a volcano's opening can grow into a mound or cone shape as successive eruptions send more lava onto the surface, where it cools into hard rock.

amphibians: A group of animals that includes frogs, salamanders and caecilians. Amphibians have backbones and can breathe through their skin. Unlike reptiles, birds and mammals, unborn or unhatched amphibians do not develop in a special protective sac called an amniotic sac.

breed: (verb) To produce offspring through reproduction.

caecilian: A type of amphibian that has no legs. Caecilians have ring-shaped folds of skin called annuli, small eyes covered by skin and sometimes bone, and a pair of tentacles. Most of them live underground in the soil, but some spend their entire lives in water.

develop: To emerge or to make come into being, either naturally or through human intervention, such as by manufacturing. (in biology) To grow as an organism from conception through adulthood, often undergoing changes in chemistry, size, mental maturity, size or sometimes even shape. (as with towns) The conversion of wildland to host communities of people. This development can include the building of roads, homes, stores, schools and more. Usually, trees and grasslands are cut down and replaced with structures or landscaped yards and parks.

ectotherm: This is an animal that relies on external sources to control its body temperature. Their body temperatures change with that of their environment.

egg: The unfertilized reproductive cell made by females.

environment: The sum of all of the things that exist around some organism or the process and the condition those things create. Environment may refer to the weather and ecosystem in which some animal lives, or, perhaps, the temperature and humidity (or even the placement of things in the vicinity of an item of interest).

fetus: (Adj. fetal ) The term for a mammal or other large animal during its later-stages of development in the womb. For humans, this term is usually applied after the eighth week of development.

gills: The respiratory organ of most aquatic animals that filters oxygen out of water. Fish and other water-dwelling animals use gills to breathe.

infection: A disease that can spread from one organism to another. It's usually caused by some type of germ.

larvae: Immature insects that have a distinctly different form (body shape) than when they are adults. For instance, caterpillars are larval butterflies and maggots are larval flies. (Sometimes this term also is used to describe such a stage in the development of fish, frogs and other animals.)

limb: (in physiology) An arm or leg. (in botany) A large structural part of a tree that branches out from the trunk.

mammal: A warm-blooded animal distinguished by the possession of hair or fur, the secretion of milk by females for feeding their young, and (typically) the bearing of live young.

metamorphosis: A dramatic change from one stage in an animal's life history to the next, such as the process by which a tadpole becomes a frog or the changes that transform a caterpillar into a butterfly.

oxygen: A gas that makes up about 21 percent of Earth's atmosphere. All animals and many microorganisms need oxygen to fuel their growth (and metabolism).

reptile: Cold-blooded vertebrate animals, whose skin is covered with scales or horny plates. Snakes, turtles, lizards and alligators are all reptiles.

species: A group of similar organisms capable of producing offspring that can survive and reproduce.

tetrapod: A four-limbed animal, including amphibians, reptiles, birds and mammals.

vertebrate: The group of animals with a brain, two eyes, and a stiff nerve cord or backbone running down the back. This group includes amphibians, reptiles, birds, mammals and most fish.

Acid (noun, "AAH-sid")

This is any chemical that, when placed in a solution, releases hydrogen ions - atoms with a tiny positive electric charge. The charges make these ions react with bases, which are ions of another type. (Known as hydroxyl ions, those other ions have a negative electric charge.) Acids can eat away at many substances and tend to taste sour. When measured on a pH scale - a zero to 14 ranking of how acidic or basic chemicals are - acids measure below 7.0. And the lower the pH, the stronger - more powerful - the acid.

acid A chemical that releases hydrogen ions when dissolved in a solution. Acids have a sour taste and have a pH ranking of less than 7.0.

acidic An adjective for materials that contain acid. These materials often are capable of eating away at some minerals such as carbonate, or preventing their formation in the first place.

base (in chemistry) A chemical that produces hydroxide ions (OH-) in a solution. Basic solutions are also referred to as alkaline. (in genetics) A shortened version of the term nucleobase. These bases are building blocks of DNA and RNA molecules.

hydrogen The lightest element in the universe. As a gas, it is colorless, odorless and highly flammable. It's an integral part of many fuels, fats and chemicals that make up living tissues.

hydroxyl A chemical group, or pairing. It's made from an oxygen atom bound to a hydrogen atom, OH. In bases, it is negatively charged.

ion An atom or molecule with an electric charge due to the loss or gain of one or more electrons.

pH A measure of a solution's acidity. A pH of 7 is perfectly neutral. Acids have a pH lower than 7; the farther from 7, the stronger the acid. Alkaline solutions, called bases, have a pH higher than 7; again, the farther above 7, the stronger the base.

atom The basic unit of a chemical element. Atoms are made up of a dense nucleus that contains positively charged protons and neutrally charged neutrons. The nucleus is orbited by a cloud of negatively charged electrons.

carbon The chemical element having the atomic number 6. It is the physical basis of all life on Earth. Carbon exists freely as graphite and diamond. It is an important part of coal, limestone and petroleum, and is capable of self-bonding, chemically, to form an enormous number of chemically, biologically and commercially important molecules.

cell The smallest structural and functional unit of an organism. Typically too small to see with the naked eye, it consists of watery fluid surrounded by a membrane or wall. Animals are made of anywhere from thousands to trillions of cells, depending on their size. Some organisms, such as yeasts, molds, bacteria and some algae, are composed of only one cell.

environment The sum of all of the things that exist around some organism or the process and the condition those things create for that organism or process. Environment may refer to the weather and ecosystem in which some animal lives, or, perhaps, the temperature, humidity and placement of components in some electronics system or product.

fat A natural oily or greasy substance occurring in animal bodies, especially when deposited as a layer under the skin or around certain organs. Fat's primary role is as an energy reserve. Fat is also a vital nutrient, though it can be harmful to one's health if consumed in excess amounts.

array: A broad and organized group of objects. Sometimes they are instruments placed in a systematic fashion to collect information in a coordinated way. Other times, an array can refer to things that are laid out or displayed in a way that can make a broad range of related things, such as colors, visible at once. The term can even apply to a range of options or choices.

astronomer: A scientist who works in the field of research that deals with celestial objects, space and the physical universe.

atmosphere: The envelope of gases surrounding Earth, another planet or a moon.

Big Bang: The rapid expansion of dense matter that, according to current theory, marked the origin of the universe. It is supported by astronomers' current understanding of the composition and structure of the universe.

black hole: A region of space having a gravitational field so intense that no matter or radiation (including light) can escape.

celestial object: Any naturally formed objects of substantial size in space. Examples include comets, asteroids, planets, moons, stars and galaxies.

cosmic microwave background: A type of radiation that fills the universe with a faint glow. It seems to flow in all directions and with an equal intensity. It's the heat left over from the Big Bang and that should exist throughout the universe. It is estimated to be about 2.725 degrees above absolute zero.

cosmos: (adj. cosmic) A term that refers to the universe and everything within it.

crater: A large, bowl-shaped cavity in the ground or on the surface of a planet or the moon. They are typically caused by an explosion or the impact of a meteorite or other celestial body. Such an impact is sometimes referred to as a cratering event.

current: A fluid - such as of water or air - that moves in a recognizable direction. (in electricity) The flow of electricity or the amount of charge moving through some material over a particular period of time.

event horizon: An imaginary sphere that surrounds a black hole. The more massive the black hole, the bigger the sphere. Anything that happens inside the event horizon is invisible, because gravity is so strong that under normal circumstances even light can't escape. But according to some theories of physics, in certain situations small amounts of radiation can escape.

field: (in physics) A region in space where certain physical effects operate, such as magnetism (created by a magnetic field), gravity (by a gravitational field), mass (by a Higgs field) or electricity (by an electrical field).

focus: (in physics) The point at which rays (of light or heat for example) converge sometimes with the aid of a lens. (In vision, verb, "to focus") The action a person's eyes take to adapt to light and distance, enabling them to see objects clearly. (in behavior) To look or concentrate intently on some particular point or thing.

infrared: A type of electromagnetic radiation invisible to the human eye. The name incorporates a Latin term and means "below red." Infrared light has wavelengths longer than those visible to humans. Other invisible wavelengths include X-rays, radio waves and microwaves. Infrared light tends to record the heat signature of an object or environment.

Jupiter: (in astronomy) The solar system's largest planet, it has the shortest day length (9 hours, 55 minutes). A gas giant, its low density indicates that this planet is composed mostly of the light elements hydrogen and helium. This planet also releases more heat than it receives from the sun as gravity compresses its mass (and slowly shrinks the planet).

kelvin: A temperature scale that has units the size of those on the Celsius scale. The difference, 0 kelvin is absolute zero. So 0 kelvin is equal to -273.15 Celsius. That means 0 Celsius is equal to 273.15 kelvins. NOTE: Unlike with the Celsius and Fahrenheit scales, there is no use of the term "degrees" for numbers on the kelvin scale.

lens: (in biology) A transparent part of the eye behind the colored iris that focuses incoming light onto the light-absorbing membrane at the back of the eyeball. (in physics) A transparent material that can either focus or spread out parallel rays of light as they pass through it. (in optics) A curved piece of transparent material (such as glass) that bends incoming light in such a way as to focus it at a particular point in space. Or something, such as gravity, that can mimic some of the light bending attributes of a physical lens. (in social issues) An attitude or perspective that helps bring broad issues into focus.

light pollution: The intrusion of unwanted light into areas that would naturally remain dark. Light pollution interferes with our ability to view the night sky. It also alters the circadian rhythms of plants, animals and people.

magnetic field: An area of influence created by certain materials, called magnets, or by the movement of electric charges.

microwaves: An electromagnetic wave with a wavelength shorter than that of normal radio waves but longer than those of infrared radiation (heat) and of visible light.

molecule: An electrically neutral group of atoms that represents the smallest possible amount of a chemical compound. Molecules can be made of single types of atoms or of different types. For example, the oxygen in the air is made of two oxygen atoms (O ₂), but water is made of two hydrogen atoms and one oxygen atom (H ₂ O).

moon: The natural satellite of any planet.

network: A group of interconnected people or things. (v.) The act of connecting with other people who work in a given area or do similar thing (such as artists, business leaders or medical-support groups), often by going to gatherings where such people would be expected, and then chatting them up. (n. networking)

observatory: (in astronomy) The building or structure (such as a satellite) that houses one or more telescopes.

orbit: The curved path of a celestial object or spacecraft around a galaxy, star, planet or moon. One complete circuit around a celestial body.

peer: (noun) Someone who is an equal, based on age, education, status, training or some other features. (verb) To look into something, searching for details.

planet: A large celestial object that orbits a star but unlike a star does not generate any visible light.

range: The full extent or distribution of something.

remnant: Something that is leftover - from another piece of something, from another time or even some features from an earlier species.

Saturn: The sixth planet out from the sun in our solar system. One of the two gas giants, this planet takes 10.6 hours to rotate (completing a day) and 29.5 Earth years to complete one orbit of the sun. It has at least 82 moons. But what most distinguishes this planet is the broad and flat plane of bright rings that orbit it.

solar: Having to do with the sun or the radiation it emits. It comes from sol, Latin for sun.

sound wave: A wave that transmits sound. Sound waves have alternating swaths of high and low pressure.

spectrum: (plural: spectra) A range of related things that appear in some order. (in light and energy) The range of electromagnetic radiation types; they span from gamma rays to X rays, ultraviolet light, visible light, infrared energy, microwaves and radio waves.

star: The basic building block from which galaxies are made. Stars develop when gravity compacts clouds of gas. When they become hot enough, stars will emit light and sometimes other forms of electromagnetic radiation. The sun is our closest star.

steer: To guide the movement of something (a vehicle, a person or an idea) in some particular direction. (in agriculture) A castrated male bovine raised for meat.

sun: The star at the center of Earth's solar system. It is about 27,000 light-years from the center of the Milky Way galaxy. Also a term for any sunlike star.

supernova: (plural: supernovae or supernovas) A star that suddenly increases greatly in brightness because of a catastrophic explosion that ejects most (or sometimes all) of its mass.

system: A network of parts that together work to achieve some function. For instance, the blood, vessels and heart are primary components of the human body's circulatory system. Similarly, trains, platforms, tracks, roadway signals and overpasses are among the potential components of a nation's railway system. System can even be applied to the processes or ideas that are part of some method or ordered set of procedures for getting a task done.

troposphere: The lowest level of Earth's atmosphere. It runs from the planet's surface to a height of 8 to 14 kilometers (5 to 9 miles), depending on the latitude. It's the region where the air is thickest and where most weather occurs. Air currents moving through this region often flow not only horizontally, but often vertically (up and down).

ultraviolet: A portion of the light spectrum that is close to violet but invisible to the human eye.

universe: The entire cosmos: All things that exist throughout space and time. It has been expanding since its formation during an event known as the Big Bang, some 13.8 billion years ago (give or take a few hundred million years).

water vapor: Water in its gaseous state, capable of being suspended in the air.

wavelength: The distance between one peak and the next in a series of waves, or the distance between one trough and the next. It's also one of the "yardsticks" used to measure radiation. Visible light - which, like all electromagnetic radiation, travels in waves - includes wavelengths between about 380 nanometers (violet) and about 740 nanometers (red). Radiation with wavelengths shorter than visible light includes gamma rays, X-rays and ultraviolet light. Longer-wavelength radiation includes infrared light, microwaves and radio waves.

X-ray: A type of radiation analogous to gamma rays, but having somewhat lower energy.

Astronomers have created the most detailed image ever of powerful radio emissions blasted out by the closest feeding supermassive black hole to Earth. The emission is fueled by the central supermassive black hole of Centaurus A, a galaxy located around 12 million light-years away.

The black hole at the heart of this galaxy, one of the largest and brightest objects in the night sky when viewed in radio waves, has a mass 55 million times that of the sun and is greedily consuming gas and matter that surrounds it.

The image produced by the team shows massive lobes of plasma stretching far beyond the limits of the galaxy. These are created as the black hole ejects material at near light speed.

This causes these "radio bubbles"-visible in the radio wave region of the electromagnetic spectrum-to grow over hundreds of millions of years.

Benjamin McKinley, from the Curtin University node of the International Centre for Radio Astronomy Research (ICRAR), said that these emissions could stretch over one million light-years into space.

"These radio waves come from the material being sucked into the supermassive black hole in the middle of the galaxy," McKinley, the lead author of a paper detailing the research set to be published in Nature Astronomy, said. "It forms a disc around the black hole, and as the matter gets ripped apart going close to the black hole, powerful jets form on either side of the disc, ejecting most of the material back out into space."

McKinley points out that in the image, it appears that Centaurus A is brighter towards its center where it is more active, and where there is more energy. He continued: "Then it's fainter as you go out because the energy's been lost and things have settled down."

Handling "Extreme" Radio Jets

McKinley adds that until now radio observations had not been adequate to capture these powerful jets. He said: "Previous radio observations could not handle the extreme brightness of the jets and details of the larger area surrounding the galaxy were distorted, but our new image overcomes these limitations."

McKinley and the team conducted their observations with the Murchison Widefield Array (MWA) telescope located in Western Australia. They combined these radio images with observations made in both optical and X-ray wavelengths.

MWA director Professor Steven Tingay said the research was possible because of the telescope's extremely wide field of view, superb radio-quiet location, and excellent sensitivity. He explained that the MWA telescope is the precursor to the Square Kilometre Array (SKA), part of an initiative that aims to build the world's largest radio telescopes in Western Australia and South Africa.

Astrophysicist Massimo Gaspari, from Italy's National Institute for Astrophysics, said that the findings arrived at by the team conform to a model in physics known as Chaotic Cold Accretion (CCA).

"In this model, clouds of cold gas condense in the galactic halo and rain down onto the central regions, feeding the supermassive black hole," he said. "Triggered by this rain, the black hole vigorously reacts by launching energy back via radio jets that inflate the spectacular lobes we see in the MWA image. "

Gaspari also points out this study is one of the first to probe the multiphase CCA 'weather' over the full range of scales in such detail.

McKinely concluded: "In this research we've been able to combine the radio observations with optical and x-ray data, to help us better understand the physics of these supermassive black holes.

"We can learn a lot from Centaurus A in particular, just because it is so close and we can see it in such detail."
