Can the sun go supernova in the future?

Sweetie, the sun doesn't have enough mass to go supernova, so don't lose any beauty sleep over that one. It'll eventually swell up and turn into a red giant, inviting all the planets (including us) to a fiery BBQ before gracefully fading away as a white dwarf in a few billion years. So, worry about something more immediate, like making sure you have enough SPF for your next beach day.
