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.
