Cosmic Fireworks

A supergiant star explodes then fades away in this sequence of images from Hubble Space Telescope. The star exploded in an our spiral arm of the galaxy NGC 2525, which is about 70 million light-years from Earth, in the constellation Puppis. This sequence, recorded over a one-year period beginning in early 2018, shows the initial star, then the brilliant supernova explosion, followed by a fade-out. Supernovas and other powerful "fireworks" pop off across the universe every day. [NASA/ESA/J.DePasquale (STScI)/M.Kornmesser and M.Zamani (ESA/Hubble)/A. Riess (STScI/JHU) and the SH0ES team/DSS]
