Reprocessed late 2012. The Lagoon Nebula is a giant interstellar cloud ~4100 LY away in the constellation Sagittarius. The pink/red glow is caused by ionised Hydrogen gas. The ionisation comes from extremely bright young stars with high Ultraviolet light output. M8 is just visible to the naked eye in dark skies and easily seen in binoculars. It spans 90' x 40' which is ~3 x 1 full moon diameters and at its distance equates to 110 x 50 LY. Imagine the energy required to light that up!

Reprocessed in late 2012. The Eagle Nebula is an emission nebula contained with a young (1-2 million years) open cluster of ~460 stars that is ~6,500 light-years away in the constellation Serpens. Its name derives from its shape that is thought to resemble an eagle. It is the subject of the famous "Pillars of Creation" photograph by the Hubble Space Telescope that shows pillars of star-forming gas and dust within the nebula.
