Scientists believe they may now have a better idea of where to search for dark matter thanks to the results of a giant computer simulation reported on Wednesday. Dark matter has puzzled scientists for about 75 years when they discovered its existence from its gravitational effects. The mysterious matter is considered to account for 85 percent of the universe's mass although it cannot be seen through telescopes. Researchers at the international Virgo Consortium, including cosmologists at...

Gamma-ray bursts are by far the brightest and most powerful explosions in the Universe, second only to the Big Bang itself. So it might seem a bit surprising that a group of them has gone missing. A single gamma-ray burst (GRB) can easily outshine an entire galaxy containing hundreds of billions of stars. Powerful telescopes can see them from clear across the Universe. And because the deeper you look into space, the farther back in time you see, astronomers should be able to see GRBs from the...

For decades it was baffling. Out of the still night sky, astronomers peering through their telescopes would occasionally glimpse quick bursts of high-energy light popping off like flashbulbs at the far side of the universe. These bursts seemed impossibly powerful: to appear so bright from so very far away, they must vastly outshine entire galaxies containing hundreds of billions of stars. These explosions, called gamma ray bursts (GRBs), are by far the brightest and most energetic phenomena...

People of the 'Deep South' love a good story and they're about to get a doozy. It begins next week when researchers from 25 countries converge on Huntsville, Alabama, to share the latest findings on the biggest explosions since the Big Bang itself. The 6th Huntsville Gamma-ray Burst Symposium 2008 convenes Oct. 20th and the talking won't stop for four straight days. One speaker after another will take the audience on a wild ride from the edge of the observable Universe, where gamma-ray bursts...

About three times a second, a 10,000-year-old stellar corpse sweeps a beam of gamma-rays toward Earth. Discovered by NASA's Fermi Gamma-ray Space Telescope, the object, called a pulsar, is the first one known that only "blinks" in gamma rays. "This is the first example of a new class of pulsars that will give us fundamental insights into how these collapsed stars work," said Stanford University's Peter Michelson, principal investigator for Fermi's Large Area Telescope in Palo Alto, Calif. The...

FAIRFAX, Va., Sept. 17 /PRNewswire/ -- General Dynamics Advanced Information Systems, a business unit of General Dynamics , has successfully completed the Launch and Early Orbit Phase (LEOP) of NASA's Fermi Gamma-ray Space Telescope. Fermi, previously known as the Gamma-ray Large Area Space Telescope or GLAST, is a next-generation high-energy gamma-ray satellite designed to make observations of celestial gamma-ray sources. NASA recently renamed the satellite in honor of Prof. Enrico Fermi...

WASHINGTON -- NASA's newest observatory, the Gamma-Ray Large Area Space Telescope, or GLAST, has begun its mission of exploring the universe in high-energy gamma rays. The spacecraft and its revolutionary instruments passed their orbital checkout with flying colors. NASA announced today that GLAST has been renamed the Fermi Gamma-ray Space Telescope. The new name honors Prof. Enrico Fermi (1901 - 1954), a pioneer in high-energy physics. "Enrico Fermi was the first person to suggest how...

NASA's Goddard Space Flight Center, located in Greenbelt, Maryland, has the lead on many exciting space missions launching in the next year. These missions include a final repair trip to upgrade the famous Hubble Space Telescope and spacecraft to study powerful gamma-rays, the moon, the Sun, and Earth's weather and pollution. "This is one of the busiest periods in the history of Goddard," said Rick Obenschain, acting director of Goddard. The mission that kicked off the series of launches was...

Several bases of operations for NASA's Gamma-ray Large Area Space Telescope (GLAST) are gearing up for data from the recently launched satellite. Operations centers preparing for data from GLAST include NASA's Goddard Space Flight Center in Greenbelt, Md., NASA Marshall Space Flight Center in Huntsville, Ala., and the Stanford Linear Accelerator Center in Menlo Park, Calif. NASA Goddard is responsible for several aspects of GLAST's mission as it begins transmitting data for the world to...

The year 2008 has turned out to be a great year for NASA -- one of the best in its 40-plus year history. And the past couple of weeks have been especially impressive. Let's take a look at what NASA has accomplished. One of the most amazing feats was the successful touchdown of the Mars Phoenix Lander near the north pole of Mars. This is the first soft landing on Mars in 30 years. When the spacecraft turned on its cameras and gave us our first look, the setting appeared desolate. But the...
