Ep. 111: Nebulae

Eagle Nebula. Image credit: Hubble
When you think about the best pictures in astronomy, almost every one is a nebula; the pillars of creation in the Eagle Nebula, or the complex Helix Nebula - or my personal favorite, the Ring Nebula. They're beautiful, wispy clouds of gas and dust that signify both the birth and death of stars. Today we give tribute to nebulae.
