Researchers say that the stone's composition has never been observed before, and their main hypothesis involves a type Ia supernova, one of the brightest phenomena in the universe.
New chemistry 'forensics' indicates 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.
Standard candle (or type Ia) supernova explosions are some of the most energetic events in the Universe, happening when a dense white dwarf star subsumes another star. Now, scientists think they re found the first evidence on Earth of such a sup
