The Most Precise Measurement of an Alien World's Size Feature14-16_sq Spitzer Space Telescope Wed, Jul 23, 2014

NASA's Kepler and Spitzer space telescopes have made the most precise measurement yet of the size of a planet beyond our solar system.

NEOWISE Spots a Comet That Looked Like an Asteroid Pia18653-640 WISE Wed, Jul 23, 2014

Comet C/2013 UQ4 (Catalina) has been observed by NASA's Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) spacecraft just one day after passing through its closest approach to the sun. The comet glows brightly in infrared wavelengths, with a dust tail streaking more than 62,000 miles (100,000 kilometers) across the sky. Its spectacular activity is driven by the vaporization of ice that has been preserved from the time of planet formation 4.5 billion years ago.

Black Hole Fireworks in Nearby Galaxy Feature14-15_sq Spitzer Space Telescope Wed, Jul 02, 2014

Celebrants this Fourth of July will enjoy the dazzling lights and booming shock waves from the explosions of fireworks. A similarly styled event is taking place in the galaxy Messier 106, as seen by NASA's Spitzer Space Telescope, Chandra X-ray Observatory and the Herschel Space Observatory.

Young Sun’s Violent History Solves Meteorite Mystery Nhsc2014-010_tn Herschel Space Observatory Tue, Jul 01, 2014

Astronomers using ESA’s Herschel space observatory to probe the turbulent beginnings of a Sun-like star have found evidence of mighty stellar winds that could solve a puzzling meteorite mystery in our own back yard.

Organic conundrum in Large Magellanic Cloud Partner88_sq Spitzer Space Telescope Mon, Jun 23, 2014

A group of organic chemicals that are considered carcinogens and pollutants today on Earth, but are also thought to be the building blocks for the origins of life, may hold clues to how carbon-rich chemicals created in stars are processed and recycled in space.

Spitzer Spies an Odd, Tiny Asteroid Feature14-14_sq Spitzer Space Telescope Thu, Jun 19, 2014

Astronomers using NASA's Spitzer Space Telescope have measured the size of an asteroid candidate for NASA's Asteroid Redirect Mission (ARM), a proposed spacecraft concept to capture either a small asteroid, or a boulder from an asteroid. The near-Earth asteroid, called 2011 MD, was found to be roughly 20 feet (6 meters) in size, and its structure appears to contain a lot of empty space, perhaps resembling a pile of rubble. Spitzer's infrared vision was key to sizing up the asteroid.
