"Stellar Explosions: Latest Discoveries in Supernova Research"
TL;DR
Stockholm University astronomers have discovered an unusual Type Ia supernova called SN 2020eyj, which was detected in radio waves and showed strong helium emissions. This marks the first confirmed Type Ia supernova triggered by a white dwarf star that pulled material from a companion star with an outer layer consisting primarily of helium. Type Ia supernovae are important for measuring the expansion of the universe, and this discovery adds to our understanding of their origins.
