Star Cycle Test

Provide the correct definition for a stellar nebula

• An exploding star caused by the ending of nuclear fusion in stars that are more than 10x the size of our Sun

• Large clouds of dust and hydrogen in space

• A region of space that has such an intense amount of gravity that not even light can escape

• The dead core of a star that has participated in a supernova, but not big enough to participate in a supernova

• The dead core of a star that is smaller than our sun or up to 10x as large that is no longer producing energy
