The US Space Agency (NASA) has released a photo of a massive star that is «preparing» become a supernova. It is reported that this is a rare cosmic phenomenon that was captured.
In the frame, the star WR 124 is in the short Wolf phase — Rayet, the process of dropping its outer layers, so characteristic halos of gas and dust form around it.
WR 124 is currently about 30 times the mass of our Sun, and is located 15 thousand light-years from Earth .
