This artist's concept illustrates the two Saturn-sized planets discovered by NASA's Kepler mission. The star system is oriented edge-on, as seen by Kepler, such that both planets cross in front, or transit, their star, named Kepler-9.

Some might see a blood-red jellyfish, while others might see a pair of lips. In fact, the red-colored object in this new image from NASA's Wide-field Infrared Survey Explorer is a sphere of stellar innards.

Astronomers Dig Up Treasure Trove of Galaxy Clusters

This image is a map of the portion of the sky covered by the preliminary release of WISE data. WISE surveyed the entire sky in four infrared wavelengths in 2010. This map is centered on the Milky Way galaxy.

Mapping the Infrared Universe: Part 1

The tightly packed system, named Kepler-444, is home to five small planets in very compact orbits. The planets were detected from the dimming that occurs when they transit the disk of their parent star, as shown in this artist's conception.

Astronomers using NASA's Spitzer Space Telescope have spotted a 'dust factory' 30 million light-years away in the spiral galaxy M74. The factory is located at the scene of a massive star's explosive death, or supernova.
