Q.

The longest period of a star’s life is called...

Q.

Gravity pulls gases and dust particles in space toward one another, squeezing them into a smaller and smaller space. The temperature at the center rises and will eventually lead to nuclear fusion of hydrogen.

What stage in a stars life cycle is this describing?

Q. Hotter stars appear to be what color? 

Q. Cooler stars appear to be what color? 

Q. What determines the color of a star? 

Q.

A star at the stage in its life cycle when it stops burning hydrogen, begins burning bigger elements, and grows much bigger to a large, low-density star.

What stage in the life cycle does this describe?

Q. What fuel do stars use? 

Q.

In a large mass star, the temperature reaches more than 100 billion degrees. The repulsive forces between the iron nuclei cause a massive explosion sending the star’s mass into space in a ....

Q. Larger stars (stars with more mass) have a longer life cycle. 

Q.

A relatively small, dense star at the end of its life cycle, which generates little energy creating a faint white light and has contracted to its densest state.

What stage in the life cycle does this describe?

Q. At what stage in a stars life cycle are elements heavier than iron form? 

Q.

A series of bursts that create a cloud of gas and dust in outer space ejected by an aging star near the end of its life cycle.

What stage in the life cycle is this describing?

Q. The remains from its supernova will form a rapidly spinning, highly magnetic star called a... 

Q. In the death of a large mass star gravitational collapse is so complete that no energy or matter can escape. This is called a...
