Hubble Space Telescope images the death of a Sun-like star

We can't say with 100% accuracy what will happen to the Sun in the future, but studying older Sun-like stars enables astronomers to predict how its life is likely to play out.

When stars as massive as the Sun die they swell up to become red giants and begin shedding their outer layers into space, forming an expanding shell of gas.


Our own Sun may one day end up resembling this object, NGC 2022, known as a planetary nebula.
