🪐 In 2022, astronomers observed the star SN 2022ann in the galaxy NGC 4647 undergoing a rare "Type IIb" supernova explosion—a dramatic event where a massive star loses most of its outer hydrogen before collapsing. This type of supernova helps scientists trace how different stellar deaths enrich galaxies with new elements and can even lead to the birth of neutron stars or black holes. ✨ #supernovae⚡#galaxies⚡#nucleosynthesis⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels
