Explanation:
What lights up this castle of star formation? The familiar Eagle Nebulaglows bright in many colors at once. The above image is a composite ofthree of these glowing gas colors. Pillars of dark dust nicely outlinesome of the denser towers of star formation. Energetic light from youngmassive stars causes the gas to glow and effectively boils away part ofthe dust and gas from its birth pillar. Many of these stars willexplode after several million years, returning most of their elementsback to the nebula which formed them. This process is forming an opencluster of stars known as M16.
