Nebulae

jmarmo01 — 2024-09-17 16:47:23 UTC

A giant cloud of dust and gas in space where clouds are born. Some are so bug that it takes thousands of years for light to travel through.

Planetary Nebulae

jmarmo01 — 2024-09-17 16:53:51 UTC

A kind of nebula that forms when stars run out of fuel and start collapsing, leaving only its core. Planetary Nebulae have nothing to do with actual planets.

Supernova Remnants

jmarmo01 — 2024-09-17 16:57:29 UTC

The leftovers after a star explodes. It becomes a cloud of gas that spreads out into space. The energy from this explosion can potentially outshine the galaxy for a short time.

Diffuse Nebulae

jmarmo01 — 2024-09-17 16:59:30 UTC

Nebulae that are spread out but not as dense. Can be where stars are formed. The closest star-forming regions to earth is the "Orion Nebula."

HR Diagram

jmarmo01 — 2024-09-17 17:01:30 UTC

A special chart that shows the brightness and temperature of stars, helping us understand the different stages of a star's life. Helps predict how long a star will live based on its temperature and brightness.

Main Sequence Star

jmarmo01 — 2024-09-17 17:03:50 UTC

A star that's in the longest, middle part of its life. The sun is a main sequence star.

White Dwarf

jmarmo01 — 2024-09-17 17:05:33 UTC

After a star has run out of fuel, the small core that is left over is called a white dwarf. White dwarfs are incredibly dense.

Supergiants

jmarmo01 — 2024-09-17 17:07:36 UTC

Very big and bright stars that are at the end of their lives. They can contain 8 to 200 times the mass of the sun.

Giants

jmarmo01 — 2024-09-17 17:09:14 UTC

Big and bright stars, but not as big and bright as supergiants. They get bigger the older they get. Their outer layers are much cooler.

Nova

jmarmo01 — 2024-09-17 17:11:18 UTC

When an explosion happens on a star's surface, the star will suddenly get brighter for a short time. It's caused when one star pulls gas from another.

Supernova

jmarmo01 — 2024-09-17 17:13:43 UTC

A huge explosion that happens when a large star runs out of fuel. These explosions create the heavy elements, like gold and iron that make up planets and the human body.

Black Hole

jmarmo01 — 2024-09-17 17:16:13 UTC

A place where gravity is so strong that not even light can escape. It forms when a massive star collapses after a supernova. Because its gravity is so strong, it can bend space and time.
