The NASA/ESA’s Hubble Space Telescope has tracked the fading light of a supernova in the spiral galaxy NGC 2525, located 70 million light years away. Supernovae like this one can be used as cosmic tape measures, allowing astronomers to calculate the distance to their galaxies. Hubble captured these images as part of one of its major investigations, measuring the expansion rate of the Universe, which can help answer fundamental questions about our Universe’s very nature.

The supernova, formally known as SN2018gv, was first spotted in mid-January 2018. The NASA/ESA’s Hubble Space Telescope began observing the brilliant brightness of the supernova in February 2018 as part of the research program ... The Hubble images center on the barred spiral galaxy NGC 2525, which is located in the constellation of Puppis in the Southern Hemisphere.

The supernova is captured by Hubble in exquisite detail within this galaxy in the left portion of the image. It appears as a very bright star located on the outer edge of one of its beautiful swirling spiral arms. This new and unique time-lapse of Hubble images created by the ESA/Hubble team shows the once bright supernova initially outshining the brightest stars in the galaxy, before fading into obscurity during the year of observations. This time-lapse consists of observations taken over the course of one year, from February 2018 to February 2019. ...
