Nebulae

bmoren111 — 2024-09-17 17:11:18 UTC

A nebulae consists of clouds made out of gas and dusts. These clouds create ionized hydrogen and cosmic dust.

Fun Fact

Nebulae are always in motion, even though they look still in images.

HR diagram

bmoren111 — 2024-09-17 18:10:36 UTC

The H-R diagram is a scatter plot of stars showing the relationship between the stars' magnitudes and luminosities .

Fun fact

It is a very useful graph because it can be used to chart the life cycle of a star.

Nova

bmoren111 — 2024-09-17 18:15:46 UTC

a star that shows a sudden large increase in brightness , then slowly returns to its original state over a few months.
Fun Fact
A nova can become one of the brightest object in the sky.

Main sequence star

bmoren111 — 2024-09-17 18:19:42 UTC

In astronomy, the main sequence star is a classification of stars that appear on plots of stellar color versus brightness.

Fun Fact

Depending on their temperature, main sequence stars can appear different colors.

Black Hole

bmoren111 — 2024-09-17 18:30:25 UTC

A black hole is a place in space where gravity pulls so much that even light can not get out.

Fun Fact

A black hole is called a black hole because of it’s color, especially since light can’t escape.

White Dwarf

bmoren111 — 2024-09-18 16:09:02 UTC

A white dwarf is what stars like the Sun become after they have exhausted their nuclear fuel.

Fun Fact

White dwarfs are some of the densest objects in the universe.

Planetary nebulae

bmoren111 — 2024-09-18 16:12:37 UTC

A planetary nebula is a region of cosmic gas and dust formed from the cast-off outer layers of a dying star.

fun fact

Planetary nebulae are created when a star runs out of fuel and dies

Supernova Remnants

bmoren111 — 2024-09-18 16:15:57 UTC

What is are supernova remnants

A supernova remnant is the structure that results from the explosion of a star in a supernova

fun fact

Supernova remnants are very important to the structure of galaxies.

Diffuse nebulae

bmoren111 — 2024-09-18 16:19:28 UTC

Diffuse nebula are the clouds of material formed from the explosions of population three.

fun fact

Some of the remaining dust and gas are believed to form planets and solar systems.

Super giants

bmoren111 — 2024-09-18 16:21:59 UTC

Supergiants are the most massive and most brightest stars.

fun fact

Supergiants can be 8 to 200 times the mass of the sun.

giants

bmoren111 — 2024-09-18 16:24:13 UTC

Giants are bigger stars.

fun fact

Giant stars have shorter lives than dwarf stars because they use up their hydrogen fuel faster

Supernova

bmoren111 — 2024-09-18 16:28:01 UTC

A supernova is a massive explosion that occurs when a star dies.

Fun fact

It is the most powerful explosion known in the universe
