Twelve Years of Spitzer Images | This montage displays an image released from each year of operation of NASA's Spitzer Space Telescope. Now celebrating it's 12th anniversary, Spitzer was first launched into space on August 25, 2003, from Cape Canaveral, Florida and is still going strong.
NASA's Hubble Space Telescope photographed three magnificent sections of the Veil Nebula -- the shattered remains of a supernova that exploded thousands of years ago. This series of images provides beautifully detailed views of the delicate, wispy structure resulting from this cosmic explosion. The Veil Nebula is one of the most spectacular supernova remnants in the sky. The entire shell spans about 3 degrees on the sky, corresponding to about 6 full moons.
#CentaurusA | Just weeks after NASA's Chandra X-ray Observatory began operations in 1999, the telescope pointed at Centaurus A (Cen A, for short). This galaxy, at a distance of about 12 million light years from Earth, contains a gargantuan jet blasting away from a central super massive black hole.
The 'Serpent' Star-Forming Cloud Spawns Stars | Within the swaddling dust of the Serpens Cloud Core, astronomers are studying one of the youngest collections of stars ever seen in our galaxy. This infrared image combines data from NASAs Spitzer Space Telescope with shorter-wavelength observations from the Two Micron All Sky Survey (2MASS), letting us peer into the clouds of dust wrapped around this stellar nursery.
