Hubble Time-Lapse of Fading Supernova in NGC 2525

This video shows a unique time-lapse of supernova 2018gv in galaxy NGC 2525, compressing a nearly one-year duration into a few seconds. The supernova is captured by Hubble in exquisite detail within this galaxy in the left portion of the frame. It appears as a very bright star located on the outer edge of the galaxy’s spiral arms. This new and unique time-lapse of Hubble images shows the once bright supernova initially outshining the brightest stars in the galaxy, before fading into obscurity during the telescope’s observations. This time-lapse consists of observations taken from February 2018 to February 2019. NGC 2525 is located nearly 70 million light-years from Earth.
