Trigger-Happy Star Formation


The Helix Nebula, lies 650 light-years away, in the constellation of Aquarius. It is a typical example of a class of objects called planetary nebula. Planetary nebulae are actually the remains of stars that once looked a lot like our sun. These stars spend most of their lives turning hydrogen into helium in massive runaway nuclear fusion reactions in their cores. In fact, this process of fusion provides all the light and heat that we get from our sun.

Cassiopeia....kind of resembles an anatomical heart to me <3
