10.25.12 - NASA's Cassini spacecraft has tracked the aftermath of a rare massive storm on Saturn.
10.24.12 - A new study using data from NASA's Spitzer Space Telescope suggests a cause for the mysterious glow of infrared light seen across the entire sky.
10.23.12 - NASA's newest set of X-ray eyes in the sky, the Nuclear Spectroscopic Telescope Array (NuSTAR), has caught its first look at the giant black hole parked at the center of our galaxy.
10.19.12 - A comprehensive study of hundreds of galaxies observed by the Keck telescopes in Hawaii and NASA's Hubble Space Telescope has revealed an unexpected pattern of change that extends back 8 billion years, or more than half the age of the universe.
10.17.12 - The following is a statement about the European Southern Observatory's latest exoplanet discovery from NASA's Science Mission Directorate Associate Administrator, Dr. John Grunsfeld.
10.11.12 - The first Martian rock NASA's Curiosity rover has reached out to touch presents a more varied composition than expected from previous missions.
10.05.12 - NASA's Swift satellite recently detected a rising tide of high-energy X-rays from a source toward the center of our Milky Way galaxy. The outburst, produced by a rare X-ray nova, announced the presence of a previously unknown stellar-mass black hole.
10.03.12 - Astronomers using NASA's Spitzer Space Telescope have announced one of the most precise measurements yet of the Hubble constant, or the rate at which our universe is stretching apart.
09.19.12 - WASHINGTON -- With the combined power of NASA's Spitzer and Hubble space telescopes, as well as a cosmic magnification effect, astronomers have spotted what could be the most distant galaxy ever seen. Light from the young galaxy captured by the orbiting observatories first shone when our 13.7-billion-year-old universe was just 500 million years old.
08.29.12 - NASA's Wide-field Infrared Survey Explorer mission has led to a bonanza of newfound supermassive black holes and extreme galaxies called hot DOGs
