The Sun (or Sol), is the star at the centre of our solar system and is responsible for the Earth's climate and weather. The Sun is an almost perfect sphere with a difference of just 10km in diameter between the poles and the equator. The average radius of the Sun is 695,508 km (109.2 x that of the Earth) of which 20-25% is the core.

Facts about the Sun

The Sun is all the colours mixed together, this appears white to our eyes.

The Sun is composed of hydrogen (70%) and Helium (28%).

The Sun is a main-sequence G2V star (or Yellow Dwarf).

The Sun is 109 times wider than the Earth and 330,000 times as massive.

The Sun's surface area is 11,990 times that of the Earth's.

The distance between the Earth and the Sun is an Astronomical Unit (AU)

One million Earths could fit inside the Sun.
A hollow Sun would fit around 960,000 spherical Earths. If squished inside with no wasted space, then around 1,300,000 would fit inside. The Sun's surface area is 11,990 times that of the Earth's.

The Sun contains 99.86% of the mass in the Solar System.
The mass of the Sun is approximately 330,000 times greater than that of Earth. It is almost three quarters Hydrogen, whilst most of the remaining mass is Helium.

The Sun is an almost perfect sphere.
There is a 10 kilometre difference between the Sun's polar and equatorial diameter. This means it is the closest thing to a perfect sphere that has been observed in nature.

The Sun will consume the Earth.
When the Sun has burned all its Hydrogen, it will continue to burn helium for 130 million more years. During this time it will expand to the point that it will engulf Mercury, Venus, and the Earth. At this stage it will have become a red giant

The Sun will one day be about the size of Earth.
After its red giant phase, the Sun will collapse. It will keep its enormous mass with the approximate volume of our planet. When this happens, it will have become a white dwarf.

The temperature inside the Sun can reach 15 million degrees Celsius.
Energy is generated at the Sun's core, by nuclear fusion, as Hydrogen converts to Helium. Hot objects expand, the Sun would explode if it weren't for its enormous gravitational force. The temperature on the surface of the Sun is closer to 5,600 degrees Celsius.

Light from the Sun takes eight minutes to reach Earth.
The Sun is an average distance of 150 million kilometres from Light travels at 300,000 kilometres per second. dividing one by the other gives us an approximate time of 500 seconds, or eight minutes and 20 seconds. Although this energy reaches Earth in a few minutes, it will already have taken millions of years to travel from the Sun's core to its surface.

The Sun travels at 220 kilometres per second.
The Sun is 24,000-26,000 light years from the galactic centre. It takes the Sun 225-250 million years to complete an orbit of the centre of the Milky Way.

The distance from the Sun to Earth changes throughout the year.
This is because the Earth travels on an elliptical orbit around the Sun. The distance between the two bodies varies from 147 to 152 million kilometres.

The Sun is middle-aged.
At around 4.6 billion years old, the Sun has already burned off about half of its store of Hydrogen. It has enough left to continue to burn Hydrogen for approximately 5 billion years. The Sun is currently a type of star known as a Yellow Dwarf.

The Sun has a very strong magnetic field.
Magnetic energy released by the Sun during magnetic storms causes solar flares. We see these as sunspots. In sunspots, the magnetic lines twist and they spin, much like a tornado would on Earth.

The Sun generates solar wind.
The wind is a stream of charged particles. This travels at approximately 450 kilometres per second through the solar system. Solar wind occurs when the magnetic field of the Sun extends into space.

Sound-it's almost impossible to imagine a world without it. It's probably the first thing you experience when you wake up in the morning-when you hear birds chirping or your alarm clock bleeping away. Sound fills our days with excitement and meaning, when people talk to us, when we listen to music, or when we hear interesting programs on the radio and TV. Sound may be the last thing you hear at night as well when you listen to your heartbeat and drift gradually into the soundless world of sleep. Sound is fascinating-let's take a closer look at how it works!

Photo: Sound is energy we hear made by things that vibrate. Photo by William R. Goodwin courtesy of US Navy.

What is sound?

Sound is the energy things produce when they vibrate (move back and forth quickly). If you bang a drum, you make the tight skin vibrate at very high speed (it's so fast that you can't usually see it), forcing the air all around it to vibrate as well. As the air moves, it carries energy out from the drum in all directions. Eventually, even the air inside your ears starts vibrating-and that's when you begin to perceive the vibrating drum as a sound. In short, there are two different aspects to sound: there's a physical process that produces sound energy to start with and sends it shooting through the air, and there's a separate psychological process that happens inside our ears and brains, which convert the incoming sound energy into sensations we interpret as noises, speech, and music. We're just going to concentrate on the physical aspects of sound in this article.

Sound is like light in some ways: it travels out from a definite source (such as an instrument or a noisy machine), just as light travels out from the Sun or a light bulb. But there are some very important differences between light and sound as well. We know light can travel through a vacuum because sunlight has to race through the vacuum of space to reach us on Earth. Sound, however, cannot travel through a vacuum: it always has to have something to travel through (known as a medium), such as air, water, glass, or metal.

Robert Boyle's classic experiment

The first person to discover that sound needs a medium was a brilliant English scientist known as Robert Boyle (1627-1691). He carried out a classic experiment that you've probably done yourself in school: he set an alarm clock ringing, placed it inside a large glass jar, and while the clock was still ringing, sucked all the air out with a pump. As the air gradually disappeared, the sound died out because there was nothing left in the jar for it to travel through.

Artwork: Robert Boyle's famous experiment with an alarm clock.

1. Put a ringing alarm clock inside a large glass case with a valve on top. Close the valve so no air can get in.

2. You can easily hear the clock ringing because the sound travels through the air in the case and the glass, before continuing to your ears.

3. Switch on the vacuum pump and remove the air from the case. As the case empties, the ringing clock sounds fainter and fainter until you can barely hear it at all. With little or no air in the case, there's nothing to carry the sound to your ears.

4. Switch off the pump. With the clock still ringing, open the valve on top of the case. As air rushes back in, you'll hear the clock ringing once again. Why? Because with air once again inside the case, there's a medium to carry the sound waves from the ringing clock to your ears.

How sound travels

When you hear an alarm clock ringing, you're listening to energy making a journey. It sets off from somewhere inside the clock, travels through the air, and arrives some time later in your ears. It's a little bit like waves traveling over the sea: they start out from a place where the wind is blowing on the water (the original source of the energy, like the bell or buzzer inside your alarm clock), travel over the ocean surface (that's the medium that allows the waves to travel), and eventually wash up on the beach (similar to sounds entering your ears). If you want to learn more about how sea waves travel, read our article on surfing science.

Artwork: Sound waves and ocean waves compared. Top: Sound waves are longitudinal waves: the air moves back and forth along the same line as the wave travels, making alternate patterns of compressions and rarefactions. Bottom: Ocean waves are transverse waves: the water moves back and forth at right angles to the line in which the wave travels.

There is one crucially important difference between waves bumping over the sea and the sound waves that reach our ears. Sea waves travel as up-and-down vibrations: the water moves up and down (without really moving anywhere) as the energy in the wave travels forward. Waves like this are called transverse waves. That just means the water vibrates at right angles to the direction in which the wave travels. Sound waves work in a completely different way. As a sound wave moves forward, it makes the air bunch together in some places and spread out in others. This creates an alternating pattern of squashed-together areas (known as compressions) and stretched-out areas (known as a rarefactions). In other words, sound pushes and pulls the air back and forth where water shakes it up and down. Water waves shake energy over the surface of the sea, while sound waves thump energy through the body of the air. Sound waves are compression waves. They're also called longitudinal waves because the air vibrates along the same direction as the wave travels.

To get the difference between transverse and longitudinal waves clear in your mind, take a look at these two little animations on Wikimedia Commons:

The science of sound waves

If you've ever got time on your hands while you're lazing on the beach, try watching the different ways in which waves can behave. You'll notice that waves traveling on water can do all kinds of clever things, like smashing into a wall and reflecting straight back with more or less the same intensity. They can also spread out in ripples, creep their way up the beach, and do other clever stuff. What's happening here with water waves doesn't actually have anything to do with the water: it's simply the way energy behaves when it's carried along by waves. Similar things happen with other kinds of waves-with light and with sound too.

You can reflect a sound wave off something the same way light will reflect off a mirror or water waves will bounce off a sea wall and go back out to sea. Stand some distance from a large flat wall and clap your hands repeatedly. Almost immediately you'll hear a ghostly repeat of your clapping, slightly out of step with it. What you hear is, of course, sound reflection, better known as an echo: it's the sound energy in your clap traveling out to the wall, bouncing back, and eventually entering your ears. There's a delay between the sound and the echo because it takes time for the sound to race to the wall and back (the bigger the distance, the longer the delay).

Picture: Reflected sound is extremely useful for "seeing" underwater where light doesn't really travel-that's the basic idea behind sonar. Here's a side-scan sonar (reflected sound) image of a World War II boat wrecked on the seabed. Photo courtesy of U.S. National Oceanographic and Atmospheric Administration and US Navy.

Sound waves lose energy as they travel. That's why we can only hear things so far and why sounds travel less well on blustery days (when the wind dissipates their energy) than on calm ones. Much the same thing happens on the oceans. Crisp water waves can sometimes travel vast distances across the ocean, but they can also be messed up when squally weather dissipates their energy over shorter distances.

Sound waves are like light and water waves in other ways too. When water waves traveling long distances across the ocean flow around a headland or into a bay, they spread out in circles like ripples. Sound waves do exactly the same thing, which is why we can hear around corners. Imagine you're sitting in a room off a corridor and, much further up the corridor, there's an identical room where someone is practicing a trumpet inside. Sound waves travel out from the trumpet, spreading out as they go. They ripple out down the corridor, race along it, ripple through the doorway into your room and eventually reach your ears. The tendency waves have to spread out as they travel and bend around corners is called diffraction.

Whispering galleries and amphitheaters

You might not think you could hear someone whispering if they sat a long way away, but if they can make the sound of their voice bounce off something into your ears, their voice will travel much further than usual.

If you're inside a building with a giant dome, the sounds you make will reflect off the curved roof like light rays bouncing off a mirror. Buildings that work this way are sometimes called whispering galleries. The dome of the US Capitol and the famous reading room in the British Museum in London are two well known examples. You can hear the same effect at work outside when you sit in a naturally curved area called an amphitheater. You can talk in a normal voice and still be heard very clearly a considerable distance away.

Measuring waves

All sound waves are the same: they travel through a medium by making atoms or molecules shake back and forth. But all sound waves are different too. There are loud sounds and quiet sounds, high-pitched squeaks and low-pitched rumbles, and even two instruments playing exactly the same musical note will produce sound waves that are quite different. So what's going on?

The energy something makes when it vibrates produces sound waves that have a definite pattern. Each wave can be big or small: big sound waves have what's called a high amplitude or intensity and we hear them as louder sounds. Loud sounds are equivalent to larger waves moving over the sea (except that, as you'll remember from up above, the air is moving back and forth, not up and down as the water does).

Apart from amplitude, another thing worth noting about sound waves is their pitch, also called their frequency. Soprano singers make sound waves with a high pitch, while bass singers make waves with a much lower pitch. The frequency is simply the number of waves something produces in one second. So a soprano singer produces more energy waves in one second than a bass singer and a violin makes more than a double bass.

Understanding amplitude and frequency

This artwork shows four waves that would sound different. If you're using a fairly up-to-date web browser, you can compare how they sound by playing the samples below. (If you don't see the sound clips, please try a different browser.)

1. The top wave represents a typical sound wave vibrating at a certain amplitude (its height) and frequency (how many peaks and troughs there are in a certain amount of time).
Your browser does not support the audio element.

2. This wave has the same frequency as the first wave (the same number of peaks and troughs) but twice the amplitude (it's twice as high). A sound wave like this would sound louder than the first wave but the same pitch.
Your browser does not support the audio element.

3. This wave has half the frequency of the second wave (half the number of peaks and troughs) but the same amplitude (it's exactly the same height). A sound wave like this would sound deeper (lower pitched) than the second wave, about as loud as the second wave, and louder than the first wave.
Your browser does not support the audio element.

4. This wave has twice the frequency of waves 1 and 2 and four times the frequency of wave 3, so it would sound much higher in pitch than the other waves. It has the same amplitude as waves 2 and 3, so it would sound just about as loud.
Your browser does not support the audio element.

Remember, however, that sound waves don't look like this as they travel. These up-and-down patterns are what you'll see if you study sound wave signals with an oscilloscope (a kind of electronic graph-drawing machine). Sound waves travel through the air as squashed-up compressions and stretched-out rarefactions. They only look like this on an oscilloscope trace.
Why instruments sound different

But here's a conundrum. If a violin and a piano make sound waves with the same amplitude and frequency, how come they sound so different? If the waves are identical, why don't the two instruments sound exactly the same? The answer is that the waves aren't identical! An instrument (or a human voice, for that matter) produces a whole mixture of different waves at the same time. There's a basic wave with a certain amplitude and pitch, called the fundamental, and on top of that there are lots of higher-pitched sounds called harmonics or overtones. Each harmonic has a frequency that's exactly two, three, four, or however many times higher than the fundamental. Every instrument produces a unique pattern of a fundamental frequency and harmonics, called timbre (or sound quality). All these waves add together to give a unique shape to the sound wave produced by different instruments, and that's one reason why they sound different. The other reason is that the amplitude of the waves made by a particular instrument changes in a unique way as the seconds tick by. Flute sounds are immediate and die quickly, while piano sounds take longer to build up and die out more slowly as well. You'll find a much longer explanation of this in our article about electronic music synthesizers.

The speed of sound

When we talk about the speed of sound, what exactly do we mean? Now you know that sound carries energy in a pattern of waves, you can see that the speed of sound means the speed at which the waves move-the speed at which the energy travels between two places. When we say that a jet airplane "breaks through the sound barrier," we mean that it accelerates so fast that it overtakes the incredibly high-intensity (that is, noisy) sound waves its engines are making, producing a horrible noise called a sonic boom in the process. That's why you'll see a fighter plane whizz overhead a second or two before you hear the vicious scream of its jet engines.

Photo: Breaking through the sound barrier creates a sonic boom. The mist you can see, which is called a condensation cloud, isn't necessarily caused by an aircraft flying supersonic: it can occur at lower speeds too. It happens because moist air condenses due to the shock waves created by the plane. You might expect the plane to compress the air as it slices through. But the shock waves it generates alternately expand and contract the air, producing both compressions and rarefactions. The rarefactions cause very low pressure and it's these that make moisture in the air condense, producing the cloud you see here. Photo by John Gay courtesy of US Navy.

The speed of sound in air (at sea level) is about 1220 km/h (760 mph or 340 meters per second). Compared to light waves, sound waves creep along at a snail's pace-about a million times slower. You see lightning much sooner than you hear it because the light waves reach you pretty much instantly, while the sound waves take about 5 seconds to cover each 1.6 km (1 mile).

One thing to note about the speed of sound is that there's really no such thing! Sound travels at different speeds in solids, liquids, and gases and even its speed in one material can change. Very roughly speaking, how fast it goes varies according to the density of the medium (how much stuff there is there). It's faster in solids than in liquids and faster in liquids than in gases: for example, sound travels about 15 times faster in steel than in air, and about four times faster in water than in air.That's why whales use sound to communicate over such long distances and why submarines use SONAR (sound navigation and ranging; a sound-based navigation system similar to radar only using sound waves instead of radio waves). It's also one of the reasons why it's very hard to figure out where the noise of a boat engine is coming from if you're swimming in the sea. (Note: The way sound travels through different materials is much more complex than this. A good explanation of why sound goes so fast in solids would mean I'd have to introduce a concept called phonons-and I'm going to skip that in this simple, introductory article, gloss over the complexities, and "pretend" that density is what makes the difference.)

Sound travels at different speeds in different gases-and can go at different speeds even in the same gas. It travels much faster in warm air near the ground than in colder air higher up, for example. And it travels roughly three times faster in helium gas than in ordinary air, because helium is much less dense. That's why people who breathe in helium talk in funny voices: the sound waves their voices make travel faster-with higher frequency.

Sound in practice

Photo: Musical sound is arguably humankind's greatest invention. This superb Steinway grand piano dates from 1876 and sits in the amazing gallery at the National Trust's Lanhydrock country house in Cornwall, England.

Sound is a hugely important part of life on Earth. Most animals listen out for noises-things that signal the possibility of eating or being eaten. Many creatures also exchange meaningful sounds, either to communicate with members of the same species or warn off predators and rivals. Humans have evolved this ability into spoken language (as a way of exchanging information) and music (essentially, a sound-based system for communicating emotion).

We've also developed a variety of different sound technologies. We've invented musical instruments that can make a huge range of different musical sounds, from simple drums and percussion instruments to sophisticated electronic synthesizers that can generate any sound you care to imagine. We can record sounds on such things as compact discs or with newer technologies like MP3 (sound files stored in highly compressed forms on computers). We can also use very high frequency sounds, known as ultrasound, for everything from cleaning false teeth to studying the development of a baby inside a mother's womb. We've even taught computers to listen to our spoken words and turn them into written language using voice recognition software-appropriately enough, that's how I wrote this article for you today!

Chemical Energy Facts

The energy that results during a chemical reaction is called chemical energy. It is a type of potential energy. Chemical energy is stored within the bonds of the atoms and molecules that make up a substance. Once chemical energy is released from a substance, the substance is transformed into a new substance.

Chemical energy is stored inside a substance or object until it is involved in a chemical reaction.

Our bodies use chemical energy to perform daily functions.

During an exothermic chemical reaction, chemical energy in the form of heat is released.

Plants perform a chemical reaction each time they use sunlight to make their own food during photosynthesis.

Cooking is a good example of a chemical reaction that releases chemical energy.

There are six basic types of chemical reactions: combustion, synthesis, single displacement, decomposition, double displacement, and acid-base.

During combustion, chemical energy in the form of heat is released when oxygen combines with other substances to form water and carbon dioxide.

When two simple substances combine to make a more complex substance during a chemical reaction it is called synthesis.

Single displacement is a chemical reaction in which some atoms from one substance are transferred to another substance.

When a complex substance breaks down into simpler substances during a chemical reaction, decomposition has occurred.

Double displacement occurs when the atoms in one substance are exchanged with atoms of another substance during a chemical reaction.

Acid-base is a double replacement chemical reaction that involves acids and bases.

Chemical energy is used to make electricity when fossil fuels are burned.

Batteries and explosives are other examples of objects that contain stored chemical energy.

During the process of digestion, chemical energy is released when food is broken down.

What Is Thermal Energy?

Have you ever wondered what makes something hot? The answer may be more simple than you think. The temperature of an object increases when the molecules that make up that object move faster.

Thermal energy is energy possessed by an object or system due to the movement of particles within the object or the system. Thermal energy is one of various types of energy, where ' energy' can be defined as 'the ability to do work.' Work is the movement of an object due to an applied force. A system is simply a collection of objects within some boundary. Therefore, thermal energy can be described as the ability of something to do work due to the movement of its particles.

Because thermal energy is due to the movement of particles, it is a type of kinetic energy, which is the energy due to motion. Thermal energy results in something having an internal temperature, and that temperature can be measured - for example, in degrees Celsius or Fahrenheit on a thermometer. The faster the particles move within an object or system, the higher the temperature that is recorded.

Application of Thermal Energy

Let's take a look at a simple example of thermal energy. A heated element on a stove contains thermal energy, and the more you turn up the stove, the more internal energy the stove contains. At the very basic level, this thermal energy is the movement of the molecules that make up the metal of the stove's element. I know you can't see the molecules moving, but they are. The faster the molecules, the more internal thermal energy they contain.

Now, let's place a pot of water on top of the heated element. What happens? The stove works, right? Well, not as we would typically think of it. Here, 'work' is referring to 'the movement of something when a force is applied.' Specifically, the thermal energy of the stove causes the particles of the pot and eventually the water to move faster. The internal energy of the heated element is transferred to the pot and ultimately the water within the pot. This transfer of thermal energy from the stove to the pot and to the water is referred to as heat. It is very important to keep these terms straight. In this context, heat is the term we use to refer specifically to the transfer of thermal energy from one object or a system to another, transfer being the key. The thermal energy is the energy possessed within the object or within the system due to movement of particles. They're different - heat and thermal energy.

You can feel the heat if you hold your hand above the stove. The heat, in turn, speeds up the molecules within the pot and the water. If you place a thermometer in the water, as the water heats up, you can watch the temperature rise. Again, an increase in internal energy will result in an increase in temperature.

# data[].attributes.attachment_link.description
Have you ever wondered what makes something hot? The answer may be more simple than you think. The temperature of an object increases when the molecules that make up that object move faster. Thermal energy is energy possessed by an object or system due to the movement of particles within the object or the system.

When a pond's surface is calm, you can see more clearly into its depths. As it turns out, the same is true for the sun.

Researchers are excited that the sun's surface is calmer now than it's been in almost a century. It's a rare opportunity - the first since the Space Age began - to peer more clearly into the sun's mysterious interior.

[image-77]

To take advantage of the opportunity, NASA is about to launch the Solar Dynamics Observatory (SDO). SDO is expected to launch this year, as early as November 2009.

"That's perfect timing," says Dean Pesnell, a solar physicist at the Goddard Space Flight Center in Greenbelt, Md. "The sun is experiencing a century-class solar minimum, offering the clearest possible views."

"SDO will actually see through the sun's surface," added Pesnell. "The process is a little like taking an ultrasound of a pregnant mother. You can see the baby right through the skin."

The sensor that performs this trick is called the Helioseismic and Magnetic Imager (HMI). It can sense acoustic waves moving through the sun, and turn those waves into a fairly clear image of the interior.

[image-50]

"There's a lot going on inside the sun that we don't understand," notes Todd Hoeksema, a solar physicist at Stanford University, Palo Alto, Calif. where the HMI was built. "The Solar Dynamics Observatory is bound to deliver some big discoveries."

The biggest discovery of all would be the inner workings of the solar dynamo. Deep beneath the sun's visible surface, massive currents of electrically-charged gas (plasma) circulate in patterns that give rise to the sun's powerful magnetic field. Almost all solar activity from sunspots to solar flares is regulated by this inner dynamo.

"Understanding how the dynamo works is a holy grail for stellar physics," says Pesnell. "It is the key to forecasting solar activity and space weather."

The problem is these deep flows are hidden from view. The sun's surface is bright and opaque, so it is impossible to look through it. Instead, solar physicists study the sun's interior the same way that geologists look deep into the Earth-via seismology. Just as earthquakes trigger seismic waves that travel through the Earth, shifting mass in the sun sends pressure waves rippling through its interior. These p modes (p for pressure) bounce around inside the sun, causing the star to ring like an enormous bell. HMI detects the surface vibrations, which in turn can be analyzed to reveal the depths.

[image-96]Sunspots can get in the way of the waves, distorting their times and frequencies, making it tricky to figure out what's really happening inside the complicated solar interior. That's why the current lack of sunspots is good for helioseismology.

"You have more sensitivity to what's happening deep in the sun when there's not as much interference from the surface," Hoeksema explains. At the peak of the solar cycle, sunspots are numerous. So far in 2009, the sun's surface has been free of sunspots about 80 percent of the time - the most tranquil it's been since 1913.

From a geosynchronous orbit 22,000 miles above Earth's surface, SDO will observe helioseismic waves more precisely than ever before. The current gold standard for observing the sun is a satellite called the Solar and Heliospheric Observatory, or SOHO, which maps helioseismic activity with mega-pixel resolution once every minute or so. HMI will up the ante to 16 megapixels every 45 seconds, resulting in a far more detailed view of the solar interior.

SDO will also improve on SOHO by beaming its torrent of raw data down to Earth unprocessed. Because of limited download bandwidth, SOHO performs some calculations while the data are still onboard the spacecraft. Only the results are beamed to scientists. Since SOHO was launched in 1995, scientists have since devised better ways to process the data and correct for errors. But there's no way they can apply these new techniques to SOHO imagery because the data have already been "crunched" by the time they leave the spacecraft.

To give scientists full access to its original data, SDO will have a continuous, 150 megabit per second download link. In comparison, most home high-speed internet connections are only 1 to 10 megabits per second.

Somewhere in all those p modes will be the telltale signs of solar jet streams, subsurface winds, proto-sunspots, and the solar dynamo itself - all "seen" with unprecedented clarity.

With the sun so calm, now is a great time to look.

How much energy is produced by solar panels?

A typical solar panel produces about 200 watts of electricity based on the efficiency and size of what's installed. For example, if you have 25 panels installed, you may have an output of about 5 kilowatt hours (kWh).

Geothermal energy is the heat from the Earth. It's clean and sustainable. Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma.
