Title: 
IC1340 in the Eastern Veil
Explanation: 
These ghostly filaments of interstellar gas are just a small part of the expansive Veil Nebula [ http://www.astropix.com/HTML/E_SUM_N/VEIL.HTM ], seen against a rich field of background stars in the long-necked constellation Cygnus [ http://www.seds.org/Maps/Stars_en/Fig/cygnus.html ]. Also known as the Cygnus Loop [ http://free.pages.at/visualastronomy/ds/brneb/cyg/ ngc6992.htm ], the Veil Nebula is a supernova remnant [ http://imagine.gsfc.nasa.gov/docs/science/know_l2/ supernova_remnants.html ], the expanding debris cloud created by a stellar explosion whose light first reached planet Earth from 5,000 to 10,000 years ago. About 1,400 light-years away [ http://antwrp.gsfc.nasa.gov/apod/ap030118.html ], the entire nebula now appears to span over 3 degrees on the sky, nearly 6 times the apparent size of the full moon, but is faint and can be difficult to see in small telescopes. The region captured in this beautiful, deep, color image [ http://www.starryscapes.com/nebula/ic1340.html ] is located at the southern tip of the Veil's eastern crescent [ http://www.astrosurf.com/jwisn/eastveil.htm ]. It covers about 10 light-years at the distance of the Veil and is cataloged as IC [ http://www.ngcic.org/scanned/ iconline/default.htm ]1340.
