Not long ago, the Hubble Space Telescope (HST) turned its gaze on an explosion. Astronomers had witnessed the death of a star inside the so-called Butterfly Galaxies in the constellation Virgo, about 60 million light years away. At the end of their lives, stars explode, forming what’s known as a supernova. So as soon as this supernova (called SN 2020fqv) was detected, a team of astronomers “triggered our ultra-rapid target-of-opportunity program with HST to obtain very early-time" observations of SN 2020fqv (Last Year Before Death: Observations of SN 2020fqv by TESS and Friends, bit.ly/3q5hcGB).
