This week’s featured image from the Hubble Space Telescope showcases the spiral galaxy NGC 337, located approximately 60 million light-years away in the constellation Cetus, also known as The Whale.
The stunning image merges observations captured in two different wavelengths, revealing the galaxy’s striking features. Its golden-hued center glows with the light of older stars, while its vibrant blue edges shimmer with the energy of young, newly formed stars. Had Hubble captured NGC 337 about a decade ago, it would have witnessed an extraordinary sight among the galaxy’s hot blue stars — a dazzling supernova illuminating its outskirts.
Named SN 2014cx, the supernova is remarkable for having been discovered nearly simultaneously in two vastly different ways: by a prolific supernova hunter, Koichi Itagaki, and by the All Sky Automated Survey for SuperNovae (ASAS-SN). ASAS-SN is a worldwide network of robotic telescopes that scans the sky for sudden events like supernovae.
