The star may have been as large as 50 suns and burned at a furious rate
(NASA) – Located 65 million light years away, it is a supergiant blue star that existed in a cluster of young stars in the spiral galaxy NGC 3938, as shown by the concept of this artist.
It exploded like a supernova in 2017 and archival photos of the Hubble Space Telescope were used to locate the doomed parent star, as it appeared in 2007.
The star may have been as large as 50 suns and burned at a furious rate, making it warmer and bluer than our sun. It was so hot that it lost its outer layers of hydrogen and helium.
When it exploded, astronomers classified it as a Type Ic supernova because of the lack of hydrogen and helium in the supernova spectrum.
