M1 : The Crab Nebula from Hubble Image Credit : NASA, ESA, Hubble, J. Hester, A. Loll (ASU) Explanation : This is the mess that is left when a star explodes. The Crab Nebula, the result of a supernova seen in 1054 AD, is filled with mysterious filaments. The filaments are not only tremendously complex, but appear to have less mass than expelled in the original supernova and a higher speed than e..

NGC 2736 : The Pencil Nebula Image Credit & Copyright : Howard Hedlund & Dave Jurasevich, Las Campanas Obs. Explanation : Moving from top to bottom in the frame near the center of this sharply detailed color composite, thin, bright, braided filaments are actually long ripples in a cosmic sheet of glowing gas seen almost edge-on. The shock wave plows through interstellar space at over 500,000 kil..

The Annotated Galactic Center Image Credit & Copyright : Miguel Claro (TWAN, Dark Sky Alqueva) Explanation : The center of our Milky Way galaxy can be found some 26,000 light-years away toward the constellation Sagittarius. Even on a dark night, you can't really see it though. Gaze in that direction, and your sight-line is quickly obscured by intervening interstellar dust. In fact, dark dust clo..
