Date: 2020-10-23

In today's image, we see a spiral galaxy known by the catalog designation of NGC 2525. Off to the lower left, the brightest star is actually a supernova seen to go off in the galaxy in January of 2018. Known as a Type Ia supernova, these objects are used to determine the distances to the galaxies and the expansion of the universe.
