Spitzer+Chandra: Object #3 53.057987-27.833524: The combined power of NASA's  Great Observatories - the Hubble Space Telescope, the Chandra X-ray  Observatory, and the Spitzer Space Telescope - have been combined to  find a hidden population of supermassive black holes in the universe. It took the penetrating view of Spitzer to finally uncover the black holes and their surrounding galaxies.

Hubble+Chandra: Object #7 53.215169-27.870226: Astronomers unveiled the deepest images from NASA's new Spitzer Space Telescope today, and announced the detection of distant objects — including several supermassive black holes — that are nearly invisible in even the deepest images from telescopes operating at other wavelengths.

A Day in the Lives of Galaxies: Like a photographer clicking random snapshots of a crowd of people, NASA/ESA Hubble Space Telescope has taken a view of an eclectic mix of galaxies. In taking this picture, Hubble's Advanced Camera for Surveys was not looking at any particular target. The camera was taking a picture of a typical patch of sky, while Hubble's infrared camera was viewing a target in an adjacent galaxy-rich region.

A bright supernova in the nearby galaxy NGC 2403: The explosion of a massive star blazes with the light of 200 million Suns in this NASA/ESA Hubble Space Telescope image. The arrow at top right points to the stellar blast, called a supernova. The supernova is so bright in this image that it easily could be mistaken for a foreground star in our Milky Way Galaxy. And yet, this supernova, called SN 2004dj, resides far beyond our galaxy. Its home is in the outskirts of NGC 2403, a galaxy located 11 million light-years from Earth. Although the supernova is far from Earth, it is the closest stellar explosion discovered in more than a decade.
