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.
By pushing NASA's Hubble Space Telescope to its limits, an international team of astronomers has shattered the cosmic distance record by measuring the farthest galaxy ever seen in the universe. This surprisingly bright, infant galaxy, named GN-z11, is seen as it was 13.4 billion years in the past, just 400 million years after the big bang. GN-z11 is located in the direction of the constellation of Ursa Major
Data from three of NASA's Great Observatories uncover the most massive galaxy cluster ever detected in the early universe.
A new study has found five objects with similar properties to the most luminous and massive stellar system within 10,000 light-years of Earth.
Nine NITARP alumni educators, some of their current students, and a student alumna have all returned this year to AAS, paying their own way to attend the international conference.
More than 50 teachers, students and astronomy educators from the NASA/IPAC Teacher Archive Research Program (NITARP) will be attending the winter meeting of the American Astronomical Society (AAS).
Astronomers are finding dozens of the fastest stars in our galaxy with the help of images from NASA's Spitzer Space Telescope and Wide-field Infrared Survey Explorer, or WISE.
Engineers and scientists have been busy recovering the Spitzer Space Telescope from standby mode since it experienced an anomaly on Nov. 26, 2015. On Dec. 14, they successfully turned on the telescope's primary instrument, the infrared array camera, or IRAC.
The fantasy creations of the "Star Wars" universe are strikingly similar to real planets in our own Milky Way galaxy. A super Earth in deep freeze? Think ice-planet "Hoth." And that distant world with double sunsets can't help but summon thoughts of sandy "Tatooine."
A survey of 10 hot, Jupiter-sized exoplanets conducted with NASA’s Hubble and Spitzer space telescopes has led a team to solve a long-standing mystery -- why some of these worlds seem to have less water than expected.
Astronomers have discovered what appears to be a tiny star with a giant, cloudy storm, using data from NASA's Spitzer and Kepler space telescopes. The dark storm is akin to Jupiter's Great Red Spot: a persistent, raging storm larger than Earth.
On Nov. 26, NASA's Spitzer Space Telescope entered into a standby mode while executing regular calibration observations. This mode is triggered by the spacecraft's fault protection system when an anomaly occurs. It puts Spitzer in a standby configuration until further instructions from the ground are received.
Astronomers harnessing the combined power of NASA’s Hubble and Spitzer space telescopes have found the faintest object ever seen in the early universe. It existed about 400 million years after the big bang, 13.8 billion years ago.
A star called KIC 8462852 has been in the news recently for unexplained and bizarre behavior. New clues emerge in the mystery of a star with odd light patterns.
ESO’s VISTA survey telescope has spied a horde of previously hidden massive galaxies that existed when the Universe was in its infancy. By discovering and studying more of these galaxies than ever before, astronomers have, for the first time, found out exactly when such monster galaxies first appeared.
Astronomers have discovered a giant gathering of galaxies in a very remote part of the universe, thanks to NASA's Spitzer Space Telescope and Wide-field Infrared Survey Explorer (WISE). The galaxy cluster, located 8.5 billion light-years away, is the most massive structure yet found at such great distances.
Astronomers have discovered a rare beast of a galaxy cluster whose heart is bursting with new stars. The unexpected find, made with the help of NASA's Spitzer and Hubble space telescopes, suggests that behemoth galaxies at the cores of these massive clusters can grow significantly by feeding off gas stolen from another galaxy
A team of Caltech researchers that has spent years searching for the earliest objects in the universe now reports the detection of what may be the most distant galaxy ever found.
Using NASA's Spitzer Space Telescope, astronomers have confirmed the discovery of the nearest rocky planet outside our solar system, larger than Earth and a potential gold mine of science data.
NASA's New Horizons will have the support of other spacecraft during its historic Pluto flyby, with observations from their outposts across the solar system.
A new image containing data from NASA's Spitzer and Chandra space telescopes shows a cluster of young stars expected to burn for billions of years.
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.
Thanks to the unprecedented sensitivity of the telescope at the Atacama Large Millimeter Array (ALMA) in Chile, a Caltech-led team has been able to observe the dust contents of galaxies as seen just 1 billion years after the Big Bang—a time period known as redshift 5-6. These are the earliest average-sized galaxies to ever be directly observed and characterized in this way, thanks in part to observations obtained by NASA's Spitzer Space Telescope.
The wacky world of exoplanets continues to surprise astronomers. They wouldn't float like balloons or give you the chance to talk in high, squeaky voices, but planets with helium skies may constitute an exotic planetary class in our Milky Way galaxy.
An international team of astronomers, led by Yale University and the University of California scientists, pushed back the cosmic frontier of galaxy exploration to a time when the universe was only 5 percent of its present age of 13.8 billion years. The team discovered an exceptionally luminous galaxy more than 13 billion years in the past and determined its exact distance from Earth using the combined data from NASA’s Hubble and Spitzer space telescopes, and the Keck I 10-meter telescope at the W. M. Keck Observatory in Hawaii. These observations confirmed it to be the most distant galaxy currently measured, setting a new record. The galaxy existed so long ago, it appears to be only about 100 million years old.
Using NASA’s Spitzer Space Telescope, the researchers observed thermal emissions coming from the planet, called 55 Cancri e – orbiting a sun-like star located 40 light years away in the Cancer constellation – and for the first time found rapidly changing conditions, with temperatures on the hot ‘day’ side of the planet swinging between 1000 and 2700 degrees Celsius.
NASA's Spitzer Space Telescope has teamed up with a telescope on the ground to find a remote gas planet about 13,000 light-years away, making it one of the most distant planets known.
