This is today's Astronomical Photo of the Day from NASA. Isn't that absolutely incredible?
And here is the explanation given:
The Pillars of Eagle Castle

Explanation: What lights up this castle of star formation? The familiar Eagle Nebula glows bright in many colors at once. The above image is a composite of three of these glowing gas colors. Pillars of dark dust nicely outline some of the denser towers of star formation. Energetic light from young massive stars causes the gas to glow and effectively boils away part of the dust and gas from its birth pillar. Many of these stars will explode after several million years, returning most of their elements back to the nebula which formed them. This process is forming an open cluster of stars known as M16.
O.K., yes. This photo is under copyright. I am thinking it will be O.K. if I give them attribution and a link. Please go visit their home page.
