In an effort to determine if conditions were ever right on Mars to sustain life, a team of scientists, including a Michigan State University professor, has examined a meteorite that formed on the red planet more than a billion years ago.
The Danish 1.54-meter telescope located at ESO's La Silla Observatory in Chile has captured a striking image of NGC 6559, an object that showcases the anarchy that reigns when stars form inside an interstellar cloud.
While Fermi is in fine shape today, continuing its mission to map the highest-energy light in the universe, the story of how it sidestepped a potential disaster offers a glimpse at an underappreciated aspect of managing a space mission: orbital traffic control.
Scientists have used Chandra to make a detailed study of an enormous cloud of hot gas enveloping two large, colliding galaxies. This unusually large reservoir of gas contains as much mass as 10 billion Suns, spans about 300,000 light years, and radiates at a temperature of more than 7 million degrees.
As planets age they become darker and cooler. Saturn however is much brighter than expected for a planet of its age - a question that has puzzled scientists since the late 1960s. New research has revealed how Saturn keeps itself looking young and hot.
Staring at a small patch of sky for more than 50 hours with the ultra-sensitive Karl G. Jansky Very Large Array (VLA), astronomers have for the first time identified discrete sources that account for nearly all the radio waves coming from distant galaxies.
NASA, the U.S. Agency for International Development (USAID), the U.S. State Department and Nike have issued a challenge to identify 10 game-changing innovations that could enable fabric systems to enhance global economic growth, drive human prosperity and replenish the planet's resources.
Researchers from the German 'Loss of the Night' project have developed an app for Android smart phones, which counts the number of visible stars in the sky. The data from the app will be used by scientists to understand light pollution on a world wide scale.
Scientists have been searching for years to find proof of small meteors that they believe have been smashing into Saturn's rings. Cornell researchers and their colleagues announced today that they now have evidence of these collisions, thanks to images of Saturn's rings taken by NASA's Cassini spacecraft.
When galaxies form new stars, they sometimes do so in frantic episodes of activity known as starbursts. During these bursts, hundreds of millions of stars are born, and their combined effect can drive a powerful wind that travels out of the galaxy. These winds were known to affect their host galaxy - but this new research now shows that they have a significantly greater effect than previously thought.
Because it has no source of energy, a dead star - known as a white dwarf - will eventually cool down and fade away. But circumstantial evidence suggests that white dwarfs can still support habitable planets.
