Neutron stars are some of the most exotic and active objects in the universe, even if they're technically dead. 💫 engineering
, an object of such immense density that few other objects in the universe even come close.
If the star is small enough, it will likely form a white dwarf. If it is massive enough, it will end its life as a black hole. Neutron stars occupy the space in between these two outcomes, though they are by no means the typical fate of a main sequence star. Counter-intuitively, the larger the star, the quicker it burns through its fuel since the bigger the star, the greater the amount of surface area from which it can radiate away energy. So, a star that is 30 times the mass of our Sun will burn through its hydrogen fuel in a fraction of the time it would take our Sun to do the same., during which it primarily fuses helium, will finish even quicker than the billion years it will take our Sun to exhaust its helium reserves.
Understandably, the star's outer material simply bounces off the core like a racquetball hitting a concrete wall off an opening serve. This produces a sudden—and spectacular—explosion as all of that energy is directed outward into space instead, the result of which we call a supernova. These can be so energetic and luminous that we can see them even in distant galaxies.
