Supernova. NASA has published a new amazing video with the remains of a star that exploded almost 340 years ago, but which has not yet completely disappeared from the universe of which we are a part. In the video clip above you can see what NASA recorded through the telescope in the Chandra observatory, Cassiopeia A (Cas A) being the main subject of the recording, i.e. exactly what was left behind by a supernova that was a very big star.
Supernova. Those from NASA recorded the first image of the remains of the star 20 years ago, but now they thought of updating the information to see what was left there after this period. Not much has changed, a very large gathering of gases and remnants still shining very brightly after this supernova-type event, technology evolving so much that the picture now is much more colorful.

Supernova. In the 20 years, NASA also discovered the fact that the gases in the outer area of the formation have temperatures of up to 20 million degrees Fahrenheit, while some elements inside have only 20.000 degrees. Also in the outer part of what is left of this supernova there are remnants traveling at speeds of up to 11 million miles per hour, and of course the shock waves of the explosion are still spreading out into the universe.
Supernova. Practically, although more than 300 years have passed since the event took place, the universe still feels what happened there, and this is because we are talking about a brutal phenomenon. Not much is known about the star that turned into a supernova, apart from the fact that it was very large, but NASA claims that silicon, sulfur, calcium, or even iron could be found among its remains.
Supernova. Events of this kind are not very frequent, but even when they happen, they can be observed without problems for hundreds and hundreds of years.
