Viewed at wavelengths from visible light to X rays, the sun is our solar system's star performer. Observed in the light of gamma rays, however, the moon outdazzles the sun. Images taken recently by a telescope aboard the Comp-ton Gamma Ray Observatory (GRO) provide graphic evidence of this phenomenon. "As far as we know, no other branch of astronomy sees the moon brighter than the sun," says GRO investigator David J. Thompson of NASA's Goddard Space Flight Center in Greenbelt, Md. <...

Laminated PTFE membrane sterilized by radiation
Medical Textiles ; A way of sterilizing polytetrafluoroethylene (PTFE) membranes with gamma radiation, without reducing their mechanical strength, is described in US patent 5 037 457. The inventor discovered that a porous PTFE membrane can be laminated directly to one surface of a porous polyester web by heating,
Jovian moon has thin oxygen atmostphere
USA Today ; Astronomers using the Hubble Space Telescope have found evidence of a thin oxygen atmosphere on Jupiter's moon Ganymede, the largest of the Jovian satellites. The same team of scientists previously had found a tenuous veil of oxygen around another Jupiter moon, Europa. The observations also suggest
Those mysterious cosmic gamma rays.
World and I ; Upon scanning the skies for radiation at the highest energy range, astronomers have discovered surprising phenomena that demand the formulation of new concepts about the universe. Gamma rays, as the most energetic form of light, tell us about the most violent, energetic processes and objects in the

Science News ; Cosmic Ray Font: Supernova remnants rev up ions (SN: 10/1/05, p. 213) is unfortunately murky. It's confusing to state that accelerating charged particles to high speeds therefore produces cosmic rays. And what charged particles ? Is the energized gas in fact ionized ? Energized is too general a
Polymer conductor mixed with charged particles in magnets.(POLYMERS/CERAMICS)
Advanced Materials & Processes ; A polymer blend made by combining a polymer that conducts electricity with another that forms charged particles has reportedly been found to have magnetic properties by Dr. Naveed Zaidi and his team of researchers at the University of Durham, Durham, U.K. The electrically conductive polymer is
Radiation may help keep arteries unclogged
The Milwaukee Journal Sentinel ; Radiation may help keep arteries unclogged By LINDA A. JOHNSON Associated Press Monday, January 29, 2001 Zapping arteries with radiation after clearing out blockages dramatically cuts the chances they will clog up again, researchers say. Two new studies suggest that the technology can help
Ganymede may have an aurora of its own. (moon of Jupiter shows evidence that it has a natural polar light display)(Brief Article)
Science News ; Auroras aren't just for planets anymore. Typically generated when a magnetic field sends charged particles crashing into a planet's atmosphere, the shimmering lights of an aurora grace the north and south polar skies of Earth, Jupiter, Saturn, Uranus, and Neptune. It now seems that Jupiter's moon
Hubble images Jupiter's aurora. (Brief Article)
Science News ; Last February, while the Ulysses spacecraft probed the magnetic field surrounding Jupiter (SN: 2/22/92, p.118), the Hubble Space Telescope recroded the first ultraviolet image of an aurora above Jupiter. The image represents the sharpest picture of this Jovian phenomenon ever taken at any
