Titanium bubbles found in Cassiopeia A

Titanium has been discovered in the residues of Cassiopeia A is a supernova which is about 11,000 light-years away. This study was published in the journal Nature.

According to the new study this discovery could help scientists understand what leads some giant stars to explode. The observations of supernovae were made using NASA’s Chandra X-ray Observatory, which has been in operation since 1999, between 2000 and 2018. Scientists recently sifted through the data to understand more about the supernova that has captivated researchers for years.

Cassiopeia A is a giant bubble of hot, expanding gas, and it’s the youngest known remnant from a supernova explosion, dating back 340 years ago, in our Milky Way galaxy. The light from this supernova first reached Earth in the 1670s.Researchers have used space-based observatories to study Cassiopeia A for years because it’s relatively nearby, astronomically speaking and provides insight into the evolution of the universe.When stars explode, they release their elements into space. Telescopes like Chandra can help unlock which ones Cassiopeia A contributed when it exploded.

While stars with masses more than 10 times our sun are known to explode once they run out of fuel, scientists don’t exactly know why this occurs. The explosions of stars have led to the release of heavy elements throughout the universe, like gold and titanium, that are found on Earth.Toshiki Sato, an assistant professor in the department of physics at Rikkyo University in Tokyo and the lead author said that scientists think most of the titanium that is used in our daily lives like in electronics or jewelry is produced in a massive star’s explosion. Scientists have never been able to capture the moment just after stable titanium is made.
