Orion Nebula in Oxygen, Hydrogen, and Sulfur Image Credit Copyright: César Blanco González The Orion Nebula is among the most intensely studied celestial features.The nebula has revealed much about the process of how stars and planetary systems are formed from collapsing clouds of gas and dust. Astronomers have directly observed protoplanetary disks, brown dwarfs, intense and turbulent motions of the gas, and the photo-ionizing effects of massive nearby stars in the nebula.

Astronomers using NASA's Hubble Space Telescope have imaged what may be water vapor plumes erupting off the surface of Jupiter's moon Europa. This finding bolsters other Hubble observations suggesting the icy moon erupts with high altitude water vapor plumes.
NASA announced that they believe two moons in our solar system might have water! Why do we keep searching for water outside of Earth?
