USRA Sponsors Poster Awards at Fermi Gamma-Ray Burst Symposium

COLUMBIA, Md., Dec. 8 /PRNewswire-USNewswire/ -- The Universities Space Research Association (USRA) highlighted its ongoing participation in and support of the Fermi Gamma-ray Space Telescope mission by joining conference organizers in sponsoring a poster prize competition at the Fermi Gamma-ray Burst Symposium held during October 20-23, 2008 in Huntsville, AL. Hosted by the Fermi Gamma-ray Burst Monitor (GBM) team, the conference featured lectures and presentations by experts in the field of gamma-ray astronomy from 25 nations, as well as reports on the most recent findings from both Fermi and NASA's Swift mission. Special emphasis was given to early observations from Fermi and presentations were featured that provided symposium participants with the first results on gamma-ray bursts from the Fermi GBM and Large Area Telescope (LAT).

Fermi discovers a gamma-ray-only pulsar

The first highlight of the recently launched Fermi Gamma-Ray Space Telescope is the discovery of a new type of object: a gamma-ray pulsar without detectable pulsations at radio, optical or X-ray wavelengths. Scientists think that most of the unidentified gamma-ray sources in the Milky Way could be such young pulsars.

WR 104 Won't Kill Us After All

Early last year, concern was growing for a Wolf-Rayet star named WR 104 that appeared to be aiming right at Earth (see Looking Down the Barrel of A Gamma Ray Burst). A Wolf-Rayet star is a highly unstable star coming to the end of its life, possibly culminating in a powerful, planet-killing gamma-ray burst (GRB). GRBs are collimated beams of high energy gamma-rays, projected from the poles of a collapsing Wolf-Rayet star. It was little wonder that we were concerned when a dying Wolf-Rayet star was found to be pointing right at us! Today, at the AAS in Long Beach, one scientist working at the Keck Telescope has taken a keen interest in WR 104 and shared new findings that show our Solar System may not be bathed in deadly gamma-rays after all…

Gamma-Ray Burst Used To Study Star Formation

The brilliant afterglow of a powerful gamma-ray burst (GRB) has enabled astronomers to probe the star-forming environment of a distant galaxy, resulting in the first detection of molecular gas in a GRB host galaxy. By analyzing the spectrum of light emitted in the GRB afterglow, the researchers are gleaning insights into an active stellar nursery in a galaxy so far away it appears as it was 10 billion years ago.

Gamma-Ray Burst Offers Peek at a Young Galaxy's Star Factory

Astronomers combining data from NASA's Swift satellite, the W. M. Keck Observatory in Hawaii, and other facilities have, for the first time, identified gas molecules in the host galaxy of a gamma-ray burst. The finding provides insight into star formation when the universe was about one-sixth its present age.

NASA's Swift Looks To Comets For A Cool View

NASA's Swift Gamma-ray Explorer satellite rocketed into space in 2004 on a mission to study some of the highest-energy events in the universe. The spacecraft has detected more than 380 gamma-ray bursts, fleeting flares that likely signal the birth of a black hole in the distant universe. In that time, Swift also has observed 80 exploding stars and studied six comets.

When it comes to gamma-rays, pulsars are no longer lighthouses. This image illustrates an earlier idea in which gamma-rays (magenta) arose from the neutron star's magnetic poles, where the radio beam (not shown) originates. The new pulsars Fermi discovered show this cannot be the case. NASA/Goddard Space Flight Center Conceptual Image Lab [View Larger Image]

New Window on the High-Energy Universe

VANCOUVER, Canada—Curtain up! Light the lights! In its first four months of monitoring the heavens from orbit, NASA’s Fermi Gamma Ray Telescope has unveiled the activity of celestial objects that emit powerful gamma rays—photons that pack 20 million to more than 300 billion times the energy of visible light.

Handheld Radiation Meters detect beta, gamma, and x-rays.

December 9, 2008 - With DX-1 meter, elevated radiation levels are indicated by beeps, beginning above 10 mR/hr, and decreasing in interval to become continuous above 20 mR/hr. Able to be recalibrated via backside adjustment screw, DX-2 compacts several ranges into one scale for measuring higher levels of radiation. Both devices feature single pushbutton for activation, LED indicator for battery, internal speaker, and compressed-scale meter. They support many applications.

Astronomers get burst of details from early universe

LONG BEACH, Calif. — Like a searchlight illuminating the distant past, the afterglow of a powerful gamma-ray burst has revealed what a stellar nursery in a remote galaxy looked like just 3 billion years after the Big Bang. The burst offers one of the earliest views of a star-forming region in the universe, which is now 13.7 billion years old.

2008: A Momentous Year in Spaceflight

This was a momentous year for spaceflight. It saw the launch of the world's most powerful gamma-ray telescope, the space station's largest room, India's first moon probe, and even a space tourist who happens to be America's first second-generation space traveler.

If physicists had enough money?

I think this money would be better spent building a giant magnifying glass we can launch into orbit to simulate a gamma-ray burst’s effect on Earth. But that’s just me.
