Description:
A supernova (exploding star), SN2022hrs (arrow), was discovered just 2 weeks ago, on April 16, 2022, by Amateur astronomer Koichi Itagaki of Yamagata Japan. This supernova is believed to be the result of a collapsing white dwarf star in the galaxy NGC4647, though the larger galaxy NGC4649 (AKA M60) overlaps and interacts, and could well be its home. The two galaxies lie 63 million lightyears from us. Ultimately the supernova will completely collapse, becoming a neutron star or a black hole. I took this image, remotely, last night using a Planewave 17 inch (0.43 meter) telescope at the Mayhill, NM, iTelescope.net observatory. It is a stack of 15 120-second exposures processed in Pixinsight 1.8.9. Two other galaxies are visible in the image, and labeled.
