Supernovas, like the 10-light-year-wide Cassiopeia A, are the “ primary means for seeding the galaxy ” with elements essential for planets and life, such as carbon, nitrogen, oxygen, silicon ...

A Dusty Dilemma There used to be a massive star 11,000 light years away, toward the constellation Cassiopeia, but about 340 years ago it vanished in a brilliant burst of light. The giant star had ...
