Take a look at these images. They are simply breathtaking. The more you observe them, the more details you catch, and the more you enjoy the sight of a supernova. 
 Yes, what you are looking at right now is the death of a star. 
All stars eventually run out of their hydrogen gas fuel and die. 
 How a star dies is largely determined by how much matter it contains. Stars with the mass of our sun expand and become red giants. On the other hand, stars with high mass become red supergiants. 
The supernovae are caused by these supergiants. They destroy themselves in a huge explosion – the supernova - that, as seen from Earth, is colorful and magnificent. But if you were to find yourself close to a supernova, you would probably die. I mean, fair enough because in any case, the death of massive stars can trigger the birth of other stars. You die, but someone else might be born.
 
 In this video, however, we want to understand if there is a minimum safety distance between us and a star that is about to become supernova: a minimum distance that could save us.
