Astronomers Find Possible Elusive Star Behind Supernova
This image is an artist's concept of a blue supergiant star that once existed inside a cluster of young stars in the spiral galaxy NGC 3938, located 65 million light-years away. The star may have been as massive as 50 suns and burned at a furious rate, making it hotter and bluer than our Sun. When it exploded in 2017, astronomers categorized it as a Type Ic supernova because of the lack of hydrogen and helium in the supernova's spectrum. Progenitor stars to Type Ic supernovas have been hard to find. But astronomers sifting through NASA Hubble archival images may have uncovered the star that detonated as supernova 2017ein.
