Hubble And The Fingerprints Of An Ancient Merger
By Evan Gough (https://ift.tt/T9HkNgp)

NGC 7722 is a lenticular galaxy about 185 million light-years away. The Hubble captured this image when following up on a supernova that was detected here in 2022. The supernova isn't visible in the image, but this dramatic portrait doesn't need an exploding stellar diva to capture out attention. Image Credit: ESA/Hubble & NASA, R. J.

This NASA/ESA Hubble Space Telescope image shows NGC 7722, a lenticular galaxy about 187 million light-years away in the constellation Pegasus. This “lens-shaped” galaxy sits in between more familiar spiral alaxies and elliptical galaxies in the galaxy classification scheme. The dark, dramatic dust lanes are the fingerprints of an ancient galaxy merger.
