Why don't we need to worry about the sun becoming a supernova?

• The sun already became a supernova.

• It is spinning too slowly.

• It doesn't have the right elements.

• It is not big enough.

When the energy production of a star stops, what does gravity do to it?

• collapse the core

• cause it to spin rapidly

• shed the outer layers

• produce a blue light

Since most stars orbit in pairs, if one of the stars is a white dwarf, it can steal material from the other star and explode as a Type ____ supernova.

• II

• 3G

• 1a

• X

Where does most of the iron in the universe come from?

• Iron is fused in the core of some white dwarf stars and released during a Type 1a supernova.

• Iron is created as light leaves a star and interacts with the star's atmosphere.

• Recycled metal on Earth is launched into space.

• Iron was created during the big bang.
