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.

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.

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.

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.

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.

Is Flash Still Relevant on Windows Mobile?

A few of my friends were talking about the iPhone and one of them mentioned Flash as an advantage for Windows Mobile. However, I think Flash is becoming less relevant on the mobile space, as it appears in its current incarnation. FlashLite 3.1 is the equivalent of Flash 8.x for the desktop. While this is miles ahead of Flash Player 7 for Pocket PC and FlashLite 2.x, FlashLite 3.1 cannot render and play embedded Flash content that was created using Flash 9 or above.

6.7 Meter Telescope To Capture 30 Terabytes Per Night

Lumenary7204 writes "The Register has a story about the Large Synoptic Survey Telescope, a project to build a 6.7 meter effective-diameter ground-based telescope that will be used to map some of the faintest objects in the night sky. Jeff Kantor, the LSST Project Data Manager, indicates that the telescope should be in operation by 2016, will generate around 30 terabytes of data per night, and will 'open a movie-like window on objects that change or move on rapid timescales: exploding supernovae, potentially hazardous near-Earth asteroids, and distant Kuiper Belt Objects.' The end result will be a 150 petabyte database containing one of the most detailed surveys of the universe ever undertaken by a ground-based telescope. The telescope's 8.4 meter mirror blank was recently unveiled at the University of Arizona's Mirror Lab in Tucson.

Adobe Releases Preview of 64-bit Flash For Linux

Rinisari writes "Finally, the day has come. Adobe has released a pre-release version of the 64-bit Flash player. It is available at the Adobe Labs Flash Player 10 download site immediately. Where are the Windows and Mac versions? 'Release of this alpha version of 64-bit Flash Player on Linux is the first step in delivering upon Adobe's commitment to make Flash Player native 64-bit across platforms. We chose Linux as our initial platform in response to numerous requests in our public Flash Player bug and issue management system and the fact that Linux distributions do not ship with a 32-bit browser or a comprehensive 32-bit emulation layer by default. Until this pre-release, use of 32-bit Flash Player on Linux has required the use of a plugin wrapper, which prevents full compatibility with 64-bit browsers.

Macromedia Flash URL Modification Issue

There's been a report of a new vulnerability in the Flash Player that could allow maliciously authored Flash content, working in conjunction with other content on a Web server, to read the contents of files from the local file systems of Flash Player users, and send those contents back to Web servers without users' consent or knowledge. This vulnerability is limited to files whose locations and names are known or guessed ahead of time by attackers. An attacker would have to entice the user to a site under his control to exploit this vulnerability. This vulnerability can never be used to modify or delete local files. All Macromedia Flash Players are affected. Macromedia has released new versions of all Flash Players fixing this issue.

Hubble telescope working, taking photos again

This undated handout photo provided by NASA, taken by the Hubble Space Telescope, shows a pair of gravitationally interacting galaxies called Arp 147. The Hubble Space Telescope is working again, taking stunning cosmic photos after a one-month breakdown. The Hubble Space Telescope Science Institute in Baltimore said the $10 billion telescope is as good as it was before a shutdown in late September. That glitch scotched plans for spacewalking astronauts to upgrade the telescope this month. (AP Photo/NASA)

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.
