Astronomy  Picture of the Day: 11/30/13 - The Dolphin Nebula  This is SH2-188 - otherwise known as the Dolphin Nebula - a planetary nebula that's located approximately 850 light-years from Earth in the constellation of Cassiopeia A.  In the past, SH2-188 was thought to be the remnant of a supernova explosion that appeared in 1965 (it took the light 850 years to reach us), but the nebula was later confirmed to be an asymmetrical planetary nebula with a crescent-like shape.

The Cosmic Spare Tire (IC 5148) is a beautiful planetary nebula located some 3000 light-years away in the constellation of Grus (The Crane). The nebula has a diameter of a couple of light-years, and it is still growing at over 50 kilometres per second — one of the fastest expanding planetary nebulae known.

The caterpillar-shaped knot, called IRAS 20324+4057, is a protostar in a very early evolutionary stage. It is still in the process of collecting material from an envelope of gas surrounding it. The object lies 4,500 light-years away in the constellation Cygnus. -
