Located 65 million light-years away is a blue supergiant star that once existed inside a cluster of young stars in the spiral galaxy NGC 3938, as shown in this artist's concept. It exploded as a supernova in 2017 and Hubble Space Telescope archival photos were used to locate the doomed progenitor star, as it looked in 2007.
