Cassiopeia A, one of the best known supernovae by astronomers. It is much bigger than that, sn2007bi. Ed. : NASA/JPL-Caltech/STScI/CXC/SAO.

50 The supernova has created as many elements as Sun

A digital study by the Palomar Observatory of California, sn2007bi, has detected the largest supernova ever observed. Later, astronomers have continued with some of the most powerful telescopes in the world and have published their results in the journal Nature.

It is estimated that the mass of the exploding star was 200 times the Sun and that the rainbow of the elements that formed it will last months. Over time, new solar systems may be formed with these elements.

Thanks to the sn2007bi supernovel, astronomers have better understood how these giant stars are. They also hope to give clues about what happened after the Big Bang. But he has also created questions, because it seems that the star did not have hydrogen, which does not correspond to what astronomers have so far believed about this type of stars.
