NASA's Swift Catches Farthest-Ever Gamma-Ray Burst

WASHINGTON, Sept. 19 /PRNewswire-USNewswire/ -- NASA's Swift satellite has found the most distant gamma-ray burst ever detected. The blast, designated GRB 080913, arose from an exploding star 12.8 billion light-years away. "This is the most amazing burst Swift has seen," said the mission's lead scientist Neil Gehrels at NASA's Goddard Space Flight Center in Greenbelt, Md. "It's coming to us from near the edge of the visible universe." Because light moves at finite speed, looking farther into the universe means looking back in time. GRB 080913's "lookback time" reveals that the burst occurred less than 825 million years after the universe began. The star that caused this "shot seen across the cosmos" died when the universe was less than one-seventh its present age.

General Dynamics Successfully Completes On-Orbit Checkout of NASA's Fermi Gamma-Ray Space Telescope

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 (1901 - 1954), a pioneer in high-energy physics.

NASA spots 'gamma ray-only' pulsar

NASA's Fermi Gamma-ray Space Telescope (formerly known as GLAST) has spied the first "gamma ray-only" pulsar - a 10,000 year-old stellar remnant which uniquely doesn't appear to emit pulses at either radio, visible light or X-ray wavelengths in common with the 1,800 or so similar objects catalogued to date.

First gamma-ray-only pulsar observed by NASA's space telescope

About three times a second, a 10,000-year-old stellar corpse sweeps a beam of gamma-rays toward Earth. This object, known as a pulsar, is the first one known to "blink" only in gamma rays, and was discovered by the Large Area Telescope (LAT) onboard NASA's Fermi Gamma-ray Space Telescope.

Fermi Telescope Makes First Big Discovery: Gamma Ray Pulsar

NASA's Fermi Gamma-ray Space Telescope discovered the first pulsar that beams only in gamma rays. A pulsar is a rapidly spinning neutron star, the crushed core left behind when a massive sun explodes. Astronomers have cataloged nearly 1,800 pulsars. Although most were found through their pulses at radio wavelengths, some of these objects also beam energy in other forms, including visible light and X-rays. However, this new object only pulses at gamma-ray energies. "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.

'Naked-eye' Gamma-Ray Burst was Aimed Squarely at Earth

Unparalleled data from satellites and observatories around the globe show that the jet from a powerful stellar explosion this past spring was aimed almost directly at Earth. The event, called a gamma-ray burst (GRB), became bright enough for human eyes to see. The observations give astronomers the most detailed portrait of a GRB ever made.

Report Surfaces Regarding External Blu-ray Add-on for Xbox 360

Ever since Microsoft stopped producing external HD-DVD drives for the Xbox 360, rumors have been floating around in abundance that the gaming giant would go Blu-ray in the future. Despite the company repeatedly stating that they have no plans to go Blu-ray nor feeling the need to do so, and then turning around and saying that they “might” if the demand were high enough, a report released by Xbit Labs this morning seems to have put all of this to bed. According to the report, Toshiba - who have long held out on making Blu-ray players - won the contract through Tobsiba-Samsung Storage Technology to manufacture an external Blu-ray drive for the console. It was no secret to those following the HD-DVD/Blu-ray debate last year that Microsoft was unimpressed with the technology because of BD-Java support, therefore they opted to go with HD i

NASA Selects Mission to Study Mars Atmosphere

WASHINGTON, Sept. 15 /PRNewswire-USNewswire/ -- NASA has selected a Mars robotic mission that will provide information about the Red Planet's atmosphere, climate history and potential habitability in greater detail than ever before. Called the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft, the $485 million mission is scheduled for launch in late 2013. The selection was evaluated to have the best science value and lowest implementation risk from 20 mission investigation proposals submitted in response to a NASA Announcement of Opportunity in August 2006. "This mission will provide the first direct measurements ever taken to address key scientific questions about Mars' evolution," said Doug McCuistion, director of the Mars Exploration Program at NASA Headquarters in Washington.

NASA Tests Deep-Space Network Modeled On the Internet

hcg50a writes "NASA has successfully tested the first deep space communications network modeled on the Internet. Working as part of a NASA-wide team, engineers from NASA's Jet Propulsion Laboratory in Pasadena, CA, used software called Disruption-Tolerant Networking, or DTN, to transmit dozens of space images to and from a NASA science spacecraft located about 20 million miles from Earth. The store-and-forward protocol was designed by NASA in consultation with Vint Cerf. Here's a discussion from last July before the test began."

Sony is quilty of deceptive propaganda. Blu-ray video quality is only slightly better than standard DVD. For most people, this does not justify switching to Blu-ray. The picture of Blu-ray is no where near 'picture perfect' as advertised. You want picture perfect? Try HD-DVD where the video quality is equal to or better than the big screen. I know this because I own both a blu-ray player and a HD-DVD player plugged through the same 56" Samsung TV with gold-plated HDMI cables. I've decided to stop purchasing blu-ray discs until the picture is improved to rival that of HD-DVD.
