Too late to turn back now
I’m running out of sound
And I am changing, changing
And if we died right now
This fool you love somehow
Is here with you

SN 1993J, a Type IIb supernova.
Discovered by the Hubble Space Telescope, it took place in a binary system in which two interacting stars caused the explosion. Being a supernova type IIb means it contains much less hydrogen than typical supernovae. This is thought to be because the companion star was taking most of the hydrogen that surrounded the exploding main star and continued to live as a super-hot helium-star.
