Imagine you want to measure the size of a room, but it's completely dark. If you shout, you can tell if the space you're in is relatively big or small, depending on how long it takes to hear the echo after it bounces off the wall.
ESA's Herschel mission releases today a series of unprecedented maps of star-forming hubs in the plane of our Milky Way galaxy. This is accompanied by a set of catalogues listing hundreds of thousands of compact sources that span all phases leading to the birth of stars in our Galaxy.
A nebula known as "the Spider" glows fluorescent green in an infrared image from NASA's Spitzer Space Telescope and the Two Micron All Sky Survey (2MASS). The Spider, officially named IC 417, lies near a much smaller object called NGC 1931, not pictured in the image. Together, the two are called "The Spider and the Fly" nebulae. Nebulae are clouds of interstellar gas and dust where stars can form.
BBC recently released Horizon's new episode, "The Mystery of Dark Energy". Some of the footage from this episode was shot during the Euclid Consortium meeting in Lausanne, Switzerland in June 2015.
Observations from NASA's Spitzer Space Telescope have led to the first temperature map of a super-Earth planet -- a rocky planet nearly two times as big as ours. The map reveals extreme temperature swings from one side of the planet to the other, and hints that a possible reason for this is the presence of lava flows.
How do some gas giant planets end up so feverishly close to their stars? NASA's Spitzer Space Telescope finds new clues.
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.
