Space Recap (tutorial)

Where are all stars born?

• Galaxies
• Nebulas

• Supernova remnants
• Black holes

Why do small/medium sized main sequence stars not turn into red supergiants?

• They lack sufficient mass (not big enough) for the necessary fusion processes.

• They have too much mass for red supergiant formation.
• They evolve directly into black holes after the main sequence.

What stage comes after the red giant and planetary nebula?

• Black hole
• Red supergiant
• Main sequence star
• White dwarf

What is a supernova?

• A supernova is a type of black hole.
• A supernova is an astronomical explosion that occurs at the end of a star's life cycle.
• A supernova is a planet formation process.
• A supernova is a comet that orbits the sun.
