Question: Is the sun going to explode in ( a lot of numbers ) years? Or is that a myth

Katie Fala answered on 18 Nov 2019:

Based on our current understanding, stars like the sun go through life-cycles; clouds of stardust condense together to form stars, which burn for billions of years, before running out of fuel. The sun in our solar system is relatively small and when it runs out of fuel, after the core collapses, the outer layers will be expelled out as dust particles, making a new cloud of stardust which will probably go on to form a new star at some point. Hence the old saying about us all being made of stardust. The sun’s core will remain, cooling down to become a white dwarf and then a black dwarf, producing less and less light and getting colder and colder. But none of this will happen in our lifetime, I think we’re talking about 5 billion years down the line or so.
