  • Unsettled Youth: A Chaotic Planetary System

    Unsettled Youth: A Chaotic Planetary System

    22/07/2010

    During the infancy of our solar system, when our planets had not yet settled down into their orbits, this was a dangerous place to live. The planets wobbled and jostled around left over asteroids, comets and other debris floating in between their orbits, causing frequent collisions throughout our solar system.

  • Swirling Clumps of Planetary Material

    Swirling Clumps of Planetary Material

    01/06/2010

    Something appears to be pushing around a large clump of material that is in orbit of this star, and it's moving fast enough to make a difference in observations along a five month period.

  • Trigger Happy Star Formation

    Trigger Happy Star Formation

    05/02/2010

    From recent discoveries made by two of NASA's Great Observatories comes new insight into how stars are created. Large nebula's scattered all around our galaxy, act as incubators for newborn stars to ignite and grow.

  • Baby Stars Found Jumbled In Galactic Center

    Baby Stars Found Jumbled In Galactic Center

    04/09/2009

    At the center of our Milky Way galaxy is an area previously unseen by astronomers. Shrouded by clouds of swirling dusts and gases, before now our astronomers could only guess at what might lie behind this thick veil.

  • Cool Stars Have Different Mix of Life-Forming Chemicals

    Cool Stars Have Different Mix of Life-Forming Chemicals

    07/04/2009

    It's life, Jim, but not as we know it! Well, at least the building blocks of life. A new study from NASA's Spitzer Space Telescope hints that planets around stars cooler than our sun might possess a different mix of potentially life-forming chemicals.

  • Exoplanet with Wild Temperature Swings

    Exoplanet with Wild Temperature Swings

    28/01/2009

    Talk about hot flashes! A planet that heats up to extreme temperatures in a matter of hours before quickly cooling back down.

  • Dim Dwarfs

    Dim Dwarfs

    12/12/2008

    The new record-holder for dimmest known star-like object in the universe goes to twin brown dwarfs, each of which shines feebly with only one millionth the light of our sun.

  • Twin Asteroid Belts

    Twin Asteroid Belts

    13/11/2008

    The star Epsilon Eridani is even stranger than fiction. NASA's Spitzer Space Telescope has shown it has two asteroid belts.

  • Water Hit with Young Stars Best Shot

    Water Hit with Young Star's Best Shot

    18/09/2008

    Water is being blasted to pieces by a young star's laser-like jets, according to new observations from NASA's Spitzer Space Telescope. The discovery provides a better understanding of how water -- an essential ingredient for life as we know it -- is processed in emerging solar systems.

  • Spitzers Fifth Anniversary

    Spitzer's Fifth Anniversary

    25/08/2008

    NASA's Spitzer Space Telescope continues to surprise astronomers. On its fifth anniversary, we recap some of this Great Observatory's biggest discoveries.

  • Brightest Star in the Galaxy has New Competition

    Brightest Star in the Galaxy has New Competition

    15/07/2008

    A contender for the title of brightest star in our Milky Way galaxy has been unearthed in the dusty metropolis of the galaxy's center.

  • Missing Spiral Arms

    Missing Spiral Arms

    13/06/2008

    As a result of a new Spitzer Space Telescope study, two of our own Milky Way Galaxy's spiral arms have gone away.

  • Holes on Mars

    Holes on Mars

    23/05/2008

    Spitzer isn't the only infrared mission. Infrared images from another of NASA's robotic missions help us understand mysterious features on the surface of Mars.

  • Diamondoids in Space

    Diamondoids in Space

    24/03/2008

    Diamonds may be rare on Earth, but surprisingly common in space -- and new research shows that the infrared eyes of NASA's Spitzer Space Telescope are perfect for finding them.

  • Common Earths

    Common Earths

    25/02/2008

    Terrestrial planets might form around many, if not most, of the nearby sun-like stars in our galaxy. These new results suggest that worlds with potential for life might be more common than we thought.

  • Cosmic Suburbia

    Cosmic Suburbia

    04/02/2008

    Young city dwellers on Earth aren't the only ones rushing to suburbia to start families. New observations from NASA's Spitzer Space Telescope suggest that galaxies also prefer to breed stars in the cosmic suburbs.

  • Uncommon Moons

    Uncommon Moons

    19/12/2007

    New observations from NASA's Spitzer Space Telescope suggest that moons like Earth's -- that formed out of tremendous collisions -- are uncommon in the universe, arising at most in only 5 to 10 percent of planetary systems.

  • Galactic Thief Caught Stealing Gas

    Galactic Thief Caught Stealing Gas

    22/10/2007

    A big galaxy, spotted stealing gas from a passing galaxy about half its size, was caught red-handed by the Spitzer Space Telescope.

  • Dust in the Wind of Black Holes

    Dust in the Wind of Black Holes

    09/10/2007

    The dust that makes everything around us -- and even ourselves -- may have come from black holes.
