All stars begin as gas and dust called:
a stellar nebula
A star that is much larger than a Sun-like Star will blow up in a supernova and end as a neutron star or black hole
Massive Star
What is the brightest White Dwarf?
Sirius B
What is #1?
Stellar Nebula
What is #12
A Black Hole
This is a contracting cloud of gas and dust; the earliest stage of a star's life
Protostar
A gigantic explosion in which a massive star collapses and throws its outer layers into space
Supernova
Which is the brightest red supergiant \?
Betelgeuse
What is #2? 
Protostar
What is #3?
An Average Mass Star
This produces its own heat/light, average mass, and includes main-sequence stars
Average Mass Stars
This is a very small, cooled remnant of a white dwarf that emits no detectable light.
Black Dwarf
What is the brightest giant star?
Aldebaran
What is #5?
Red Giant
What is #9?
White Dwarf
This is a stellar core remnant composed mostly of electron-degenerate matter, a hot and dim star.
White Dwarf
This is a luminous giant star of low or intermediate mass in a late phase of stellar evolution, when the average mass star runs out of Hydrogen at its core and burns up its outer layers.
Red Giant
What is the dimmest Main Sequence star?
What is #4?
a Massive Star
What is #7?
Planetary Nebular
This is a type of emission nebula consisting of an expanding, glowing shell of ionized gas ejected from red giant stars late in their lives.
Planetary Nebula
The stage in the life cycle of a massive star during which the star increases in size and becomes very bright and has used up all its hydrogen fuel and has started fusing helium.
Red Supergiant
What is the brightest yellow Supergiant?
Polaris the North Star
What is #8?
Supernova
What is #11?

A Neutron Star
What is a highly dense, compact stellar remnant formed from the core of a massive star after a supernova explosion?
Neutron Star
These are the hottest, Brightest Supergiants, with very short lives, that burn very hot and fast.
Blue Supergiants
What is the stellar classification of our sun?
G2
What is #10?
Black Dwarf
What is #6

Red Super Giant
