Happy 20th Anniversary, SN1987A!
On this day in 1987,
SN1987A,
my favoritest supernova ever, blew up. According to
this diagram at the
University of Virginia,
the star started burning neon in 1971, oxygen in 1983, silicon in 1987, and blew up ten days after that. Let that be a lesson to you, young stars: neon is a gateway drug that leads to inevitable self-destruction.
