This Is What it Looks Like When a Sun Dies (Synopsis) [Starts With a Bang]

“A bit of mould is a pleiad of flowers; a nebula is an ant-hill of stars.” -Victor Hugo

In the distant future, about 7 billion years from now, our Sun will run out of all the nuclear fuel it’s capable of burning in its core. As it contracts under its own gravity, radiation becomes unable to hold it up any longer. Gravitation takes over, and the outer layers get blown off as the core contracts down into a white dwarf.

These outer layers, containing hydrogen and a slew of heavier elements, will come to enrich the interstellar medium by forming a planetary nebula. Various elements glow in different wavelengths, and the nebula takes on a variety of temperatures throughout. But most spectacularly, different shapes and morphologies come about depending on factors like the star’s rotation speed, the presence or absence of a companion and other, yet-undetermined factors.
