Hubble images NGC 941, a spiral galaxy with an explosive past
This image from NASA’s Hubble Space Telescope features the spiral galaxy NGC 941, which lies about 55 million light-years from Earth. Hubble’s Advanced Camera for Surveys (ACS) collected the data that created this image. Beautiful NGC 941 is undoubtedly the main attraction in this view; however, the hazy-looking galaxy was not the motivation for collecting the data. That distinction belongs to an astronomical event that took place in the galaxy years before: the supernova SN 2005ad.
