Astronomers have come across what appear to be two of the earliest and most primitive supermassive black holes known. The discovery, based largely on observations from NASA's Spitzer Space Telescope, will provide a better understanding of the roots of our universe, and how the very first black holes, galaxies and stars came to be.
Astronomers have used NASA's Spitzer Space Telescope rather like a doctor's stethoscope to listen in on the "heartbeat" of star formation in our galaxy, a finding that will help trace the "life" of the Milky Way and other galaxies.
Imagine finding a living dinosaur in your backyard. Astronomers have found the astronomical equivalent of prehistoric life in our intergalactic backyard: a group of small, ancient galaxies that has waited 10 billion years to come together. These "late bloomers" are on their way to building a large elliptical galaxy.
Artwork inspired by NASA's Spitzer Space Telescope is making an appearance at this year's Winter Olympics in Vancouver, British Columbia.
For almost two centuries, humans have looked up at a bright star called Epsilon Aurigae and watched with their own eyes as it seemed to disappear into the night sky, slowly fading before coming back to life again.
NASA's Spitzer Space Telescope has captured an action-packed picture of the nearby Small Magellanic Cloud, a small galaxy that looks like a wispy cloud when seen from Earth.
This composite graphic encompasses a quarter century of infrared astronomy from space, a world away from Galileo Galilei's eight-power telescope that was the cutting edge of astronomy 400 years ago. It also illustrates some of the contributions from the Infrared Processing and Analysis Center (IPAC) to this progress by way of astronomical data processing, analysis, archiving and dissemination.
In an unveiling of truly galactic proportions, the world's largest image of our Milky Way galaxy, taken by NASA's Spitzer Space Telescope, will be unveiled at the Adler Planetarium in Chicago.
NASA's Spitzer Space Telescope has contributed to the discovery of the youngest brown dwarf ever observed -- a finding that, if confirmed, may solve an astronomical mystery about how these cosmic misfits are formed.
Before our planets found their way to the stable orbits they circle in today, they wiggled and jostled about like unsettled children.
On Friday, Oct. 23, engineers with NASA's Spitzer Space Telescope successfully swapped the spacecraft from the main nitrogen thruster string to a backup thruster string.
Four hundred years ago when Galileo turned his tiny telescope to the night sky our view of the Universe changed forever. Since that historic moment, we have continued to gain an appreciation for the vastness of space, while struggling to find our place in it. We ask: Where did we come from? Are we alone? Exploring these questions, NASA's Spitzer Space Telescope Science Center is participating in the Pasadena Art & Ideas festival "Origins" with an exhibit titled: "Origins in the Universe". The festival runs October 23 - November 9, 2009 in venues across Pasadena, Calif.
Peering far beyond our solar system, NASA researchers have detected the basic chemistry for life in a second hot gas planet, advancing astronomers toward the goal of being able to characterize planets where life could exist. The planet is not habitable but it has the same chemistry that, if found around a rocky planet in the future, could indicate the presence of life.
NASA's Spitzer Space Telescope has discovered an enormous ring around Saturn â€” by far the largest of the giant planet's many rings.
Astronomers have witnessed odd behavior around a young star. Something, perhaps another star or a planet, appears to be pushing a clump of planet-forming material around. The observations, made with NASA's Spitzer Space Telescope, offer a rare look into the early stages of planet formation.
A new study from two of NASA's Great Observatories provides fresh insight into how some stars are born, along with a beautiful new image of a stellar nursery in our Milky Way galaxy. The research shows that radiation from massive stars may trigger the formation of many more stars than previously thought.
NASA's Spitzer Space Telescope has found evidence of a high-speed collision between two burgeoning planets around a young star.
NASA's Spitzer Space Telescope is starting a second career and taking its first shots of the cosmos since warming up.
NASA's Spitzer Space Telescope has imaged a wild creature of the dark â€” a coiled galaxy with an eye-like object at its center.
Testing and characterization activities continue for NASA's Spitzer Space Telescope warm mission, a process that began after the observatory's cryogen ran out on May 15.
On June 11th, Dr. Frank Low, one of the people responsible for the rise of infrared astronomy, died in Tucson. He was 75 years old.
Engineers and scientists are continuing with testing and characterization activities for the NASA Spitzer Space Telescope warm mission, a process that began after Spitzer's cryogen ran out on May 15.
Astronomers have at last uncovered newborn stars at the frenzied center of our Milky Way galaxy. The discovery was made using the infrared vision of NASA's Spitzer Space Telescope.
After more than five-and-a-half years of probing the cool cosmos, NASA's Spitzer Space Telescope has run out of the coolant that kept its infrared instruments chilled. The telescope will warm up slightly, yet two of its infrared detector arrays will still operate successfully. The new, warm mission will continue to unveil the far, cold and dusty universe.
Scientists have long wondered how tiny silicate crystals, which need sizzling high temperatures to form, have found their way into frozen comets, born in the deep freeze of the solar system's outer edges. The crystals would have begun as non-crystallized silicate particles, part of the mix of gas and dust from which the solar system developed.
The primary mission of NASA's Spitzer Space Telescope is about to end after more than five and a half years of probing the cosmos with its keen infrared eye. Within about a week of May 12, the telescope is expected to run out of the liquid helium needed to chill some of its instruments to operating temperatures.
NASA's Spitzer Space Telescope is about to use its last drop of the coolant that has chilled it for the past five-and-a-half years. On about May 12, give or take a week or so, the observatory is predicted to run out of the liquid helium that has run through its veins, keeping its infrared detectors at frosty operating temperatures of just a few degrees above the coldest temperature possible, called absolute zero.
