“Blue” Lagoon
The picture, which combines 20 hours’ worth of data collected over several days, shows the red-hued Lagoon looking a bit bluer than normal, due to the telescope’s viewing angle.Image courtesy SSRO/PROMPT/CTIO
Mysterious Monoceros
Called Monoceros R2, the interstellar cloud of gas and dust glows deep red in this recently released image due to its abundant ionized hydrogen. The picture was made using data from the Cerro Tololo Inter-American Observatory in Chile. Image courtesy T.A. Rector, UAA, and N.S. van der Bliek, NOAO/NSF
NGC 7129 [x]
Emission Nebula
An emission nebula is a cloud of high temperature gas. Within this type of nebula, a star energizes the atoms in the cloud with ultraviolet radiation. As these atoms fall back to lower energy states, they emit radiation. The process is similar to that of a neon light. This causes the nebula to glow. Emission nebulae tend to be red in color because of the abundance of hydrogen. Additional colors, such as blue and green, can be produced by the atoms of other elements, but hydrogen is almost always the most abundant.
