New chemistry "forensics" indicate that the stone named Hypatia from the Egyptian desert could be the first tangible evidence found on Earth of a supernova type Ia explosion. These rare supernovas are some of the most energetic events in the universe.
Japanese astronomers have captured images of an astonishing 1800 supernovae. 58 of these supernovae are the scientifically-important Type 1a supernovae located 8 billion light years away and are known as ‘standard candles’ in astronomy.
Many supernovae show a gradual increase in the light they put out. But for ASASSN-18bt, you could clearly see there's something unusual and exciting happening in the early times - an unexpected additional emission.
Scientists appear to have found the first X-rays coming from type Ia supernovae.
