Messier 78 Nebula
Messier 78 is easily seen in small telescopes to the naked eye in the constellation of Orion, just to the northeast of Orion's belt, but looks strikingly different, with dominant, dark swaths of dust. http://www.spitzer.caltech.edu/explor...

NASA Human Exploration Mission
NASA has announced the creation of the Human Exploration and Operations (HEO) Mission Directorate. The new organization, which combines the Space Operations and Exploration Systems mission directorates, will focus on International Space Station operations and human exploration beyond low Earth orbit.

Spitzer Space Telescope http://www.spitzer.caltech.edu/images... Named RCW 120 by astronomers, this region of hot gas and glowing dust can be found in the murky clouds encircled by the tail of the constellation Scorpius. The green ring of dust is actually glowing in infrared colors that our eyes cannot see, but show up brightly when viewed by Spitzer's infrared detectors. At the center of this ring are a couple of giant stars whose intense ultraviolet light carved out the bubble, though they blend in with the other stars when viewed in infrared.
Rings like this are so common in Spitzer's observations that astronomers have even enlisted the help of the public to help find and catalog them all. Anyone interested in joining the search as a citizen scientist can visit "The Milky Way Project," part of the "Zooniverse" of public astronomy projects,
