Potpourri
100

This is the closest star to Earth.

What is the Sun?

100

A star will begin its life as this cloud of gas and dust in space.

What is a nebula?

100

Small and medium mass stars will turn into this before cooling and fading away.

What are white dwarfs?

100
This is the small, near infinitely dense point at the center of the black hole.

What is the singularity?

100

This is the term for the Sun's atmosphere.

What is the corona?

200

These small, cool stars can burn for trillions of years.

What are red dwarfs?

200

This is the process by which stars convert fuel to energy.

What is nuclear fusion?

200
Astronomers predict that small and medium mass stars will end their lives as these cold, dark cinders.

What are black dwarfs?

200

This is the point of no return, where the black hole's gravity becomes so strong that not even light can escape.

What is the event horizon?

200

This is the heaviest element that stars can reach through fusion.

What is iron?

300

These are the stars that middle mass stars will turn into before they die, like our sun.

What are red giants?

300

A main sequence star converts this hydrogen into this element in its core.

What is helium?

300

Only the most massive stars will end their lives in this fiery event.

What is a supernova?

300

This is the swirling matter that is actively falling into the black hole, heating up through friction.

What is the accretion disk?

300

This is the phenomenon where a white dwarf steals hydrogen, eventually causing it to ignite on the surface.

What is a nova?

400

These are the largest stars, and consume fuel at an extremely fast rate

What are supergiants?

400

These are what a star is called before it ignites.

What are protostars?

400

These types of stellar corpses are held up by the repulsion of neutral particles.

What are neutron stars?

400

This is the minimum size an object must be compressed to in order to become a black hole.

What is the Schwarzschild Radius?

400
If the Earth was compressed into a black hole, it would be about as big around as this coin.

What is a quarter?

500

These are what a star is called if it fails to ignite.

What is a brown dwarf?

500

These types of star are actively burning hydrogen. Most stars will spend around 90% of their lives here.

What are main-sequence stars?

500

This is the phenomenon that allows white dwarf stars to resist their own gravity.

What is electron degeneracy pressure?

500
This is the process by which black holes eventually evaporate.

What is Hawking Radiation?

500

This is the mass limit that a star must exceed in order to become a black hole when it dies.

What is the Oppenheimer-Volkoff Limit?
