A Celestial Snow Angel

The star-forming region Sharpless 2-106 (S106) has a bi-polar shape that, in a December 2011 Hubble press release, was likened to a "celestial snow angel". The "wings" of the nebula are actually bubbles of hot gas created by stellar winds and high energy radiation coming from a massive, hot, newborn star in the center.

If you have any leftover hard-boiled eggs, you can recreate this bit of fluid dynamical fun. Spin the egg through a puddle of milk, and you'll find that the egg draws liquid up from the puddle and flights it out in a series of jets. As the egg spins, it drags the milk it touches with it.
