A nebula is a giant cloud of gas and dust that floats in space between stars.

Planetary Nebulae

sramir45 — 2024-09-17 16:52:55 UTC

A planetary nebula is a glowing cloud of gas and dust that forms when a star dies:

Supernova remnants

the debris left behind after a star explodes in a supernova

Diffuse nebulae

sramir45 — 2024-09-17 16:56:41 UTC

A diffuse nebula is a thin, widespread cloud of gas and dust in space that has no clear boundary and is often detected by the light of nearby stars.

HR Diagram

sramir45 — 2024-09-17 16:57:59 UTC

A Hertzsprung-Russell (H-R) diagram is a graph that shows the relationship between the luminosity and temperature of stars

Main sequence star

sramir45 — 2024-09-17 16:59:00 UTC

A "main sequence star" is a star that is currently fusing hydrogen into helium in its core

White dwarf

sramir45 — 2024-09-17 17:00:49 UTC

A white dwarf is a star that has reached the end of its life and is the core of a dying star that has run out of nuclear fuel

Super giants

sramir45 — 2024-09-17 17:01:44 UTC

A supergiant is a star that is extremely large and luminous, and can be several hundred times larger than the sun

Giants

sramir45 — 2024-09-17 17:02:56 UTC

Giant stars are stars that are much larger and brighter than other stars of the same color

Nova

sramir45 — 2024-09-17 17:04:05 UTC

a star that suddenly increases its light output tremendously and then fades away to its former obscurity in a few months or years

Supernova

sramir45 — 2024-09-17 17:04:47 UTC

A supernova is a star's massive explosion. It can occur when a massive star runs out of fuel and explodes, or when a white dwarf star in a binary star system explodes.

Black hole

sramir45 — 2024-09-17 17:05:46 UTC

A black hole is a region in space where gravity is so strong that nothing, including light, can escape
