Study posits sun will form nebula on death

The video discusses the sun's lifecycle, including its expansion into a red giant, potentially consuming planets like Mercury and Venus, and its eventual transformation into a white dwarf. New research suggests the sun may form a planetary nebula, a process previously thought unlikely due to insufficient core heating. However, the study indicates the sun's core could heat up three times faster than previously believed, allowing for the formation of a faint planetary nebula visible from the Andromeda Galaxy, 2 million light years away.

What is the next stage in the sun's life cycle after it becomes a red giant?

• A neutron star

• A white dwarf

• A black hole

• A supernova

What does new research suggest about the sun's future?

• It will become a black hole

• It will explode as a supernova

• It will form a planetary nebula

• It will remain a red giant indefinitely

How long can the planetary nebula phase last?

• 5,000 years

• 1,000 years

• 50,000 years

• 10,000 years

What did previous research suggest about the sun's core heating?

• It would not heat up quickly enough

• It would cool down rapidly

• It would remain at a constant temperature

• It would heat up very quickly

From where could the faint planetary nebula be visible?

• The Milky Way Galaxy

• The Andromeda Galaxy

• The Triangulum Galaxy

• The Large Magellanic Cloud
