The scientists of the "Hubble" space telescope, the holiday around the Earth, yesterday published photographs of the remains of a massive explosion of a star from the Cassiopeia constellation. The explosion, known as a supernova, happened 300 years ago.
"These are the youngest remains identified in the Milky Way galaxy, where Earth is located," said an official announcement published by the American space agency.
The exploded star is 15 to 25 times larger than the Sun. Stars of this type have a relatively short lifespan - they use up their "fuel" supply in a few tens of millions of years (a thousand times faster than our sun). Then begins a chain of events leading to the end of the star in a supernova explosion.
The images allow astronomers to study the supernova remnants in great detail. The sections that appear in the photo in deep blue color are rich in oxygen, the red ones are rich in sulfur.
