In a far-off galaxy, 12.4 billion light-years from Earth, a ravenous black hole is devouring galactic grub. Its feeding frenzy produces so much energy, it stirs up gas across its entire galaxy.
NASA's Near-Earth Object Wide-field Survey Explorer (NEOWISE) spacecraft discovered and characterized 40 near-Earth objects (NEOs) in the first year after the mission was re-started in December 2013. Eight of the discoveries have been classified as potentially hazardous asteroids (PHAs), based on their size and how close their orbits could come to Earth's orbit.
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.
A survey of more than 170,000 supermassive black holes, using NASA's Wide-field Infrared Survey Explorer (WISE), has astronomers reexamining a decades-old theory about the varying appearances of these interstellar objects.
After searching hundreds of millions of objects across our sky, NASA's Wide-Field Infrared Survey Explorer (WISE) has turned up no evidence of the hypothesized celestial body in our solar system commonly dubbed "Planet X."
NASA's Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) spacecraft has spotted a never-before-seen comet -- its first such discovery since coming out of hibernation late last year.
A decade after graduating its first class, the NASA/IPAC Teacher Archive Research Program (NITARP)—a project that brings an authentic astronomy research experience into middle, high school and community college classrooms—has had resounding success.
2013 is a significant year in infrared astronomy -- it marks the 30th anniversary of the launch of IRAS, the Infrared Astronomical Satellite, which revolutionized our view of the infrared cosmos, increasing the number of known infrared sources by about 70%. This talk will review some of the major discoveries from some of the many important infrared astronomy missions.
For NASA and its dozens of missions, data pour in every day like rushing rivers. Spacecraft monitor everything from our home planet to faraway galaxies, beaming back images and information to Earth.
On August 8, 2011 IPAC astronomer Bill Latter will live a dream by attempting a grand journey and a great challenge - both physically and mentally. Bill will be traveling the Badwater 135 Ultramarathon course on foot. This is a trek from Badwater Basin in Death Valley to the Mt. Whitney Portals above Owens Valley – a distance of 135 miles with extreme heat and 13,000 feet of ascent.
Sometimes astronomers take trips out to ground-based observatories. They sleep during the day, and, instead of peering up at the night sky, they command the telescopes from computer screens. Some telescopes can also be operated remotely from laptops. JPL scientists Amy Mainzer and Mike Cushing recently spent an evening with the stars in a conference room at NASA's Infrared Processing and Analysis Center at the California Institute of Technology in Pasadena.
The summer of 1965 was one of dramatic firsts—Medicaid and Medicare were established, the Beatles played the first stadium concert in rock history, and U.S. astronaut Edward Higgins White made his maiden space walk.
