 Here's supernova 2018 GV, the Type 1A supernova in the spiral galaxy NGC 2525, 70 million light years away. Hubble began observing it in February 2018 after the supernova was first detected by amateur astronomer Kochi Itagaki a few weeks earlier in mid-January. This was one of the supernovae used as part of the program to precisely measure the expansion rate of the universe that we covered in the How Far Away Is It segment on the cosmos. In the time-lapse sequence spanning nearly a year, the supernova first appeared as a blazing star located on the galaxy's outer edge. It initially outshines the brightest stars in the galaxy before fading out of sight.
