The filamentous remains of an exploded star

This fulldome clip shows the branching, almost organic appearance of the gas expelled by a recently deceased star. This object is call Cassiopeia A and is the result of a recent supernova explosion — the youngest such object known to exist in our Milky Way galaxy. The gas will be rich in heavier elements, like calcium and iron, which will fertilise the interstellar medium for new stars and planetary systems in the distant future.
