Eye on energy.(LETTERS)(Letter to the Editor)

"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 word. Finally, why are high-speed particles more easily compressed than slower-moving material?

FREDRIC BLUM, MERION, PA.

"Energized" means that the ...

Turning a fly's eye on energetic cosmic rays. (Fly's Eye detectors pick up high-energy cosmic rays)
Science News ; The origin of high-energy cosmic rays has long puzzled astrophysicists. Were these electrically charged particles accelerated to extremely high velocities outside the Milky Way or in turbulent, supernova-disturbed regions within our galaxy? Using two ground-based Fly's Eye detectors to pick up the

Science News ; When it comes to revving up subatomic particles, the heavens leave the biggest particle accelerator on Earth in the dust. Our galaxy abounds with charged particles carrying energies that are thousands to millions of times as high as those that the most powerful atom smashers can muster. Known as

Science News ; Of all the particles that bombard Earth, only cosmic rays provide a direct sample of matter from beyond the solar system. Moreover, these charged particles--electrons and ions that travel at nearly the speed of light--rank as the most energetic known in the universe. For decades, astronomers have

Electromagnetic News Report ; For the last couple of months I've been getting up at zero-dark-thirty, putting on my bedroom slippers and war surplus greatcoat over my pajama and sloshing through the dew on the grass in my back yard till I'm clear of the tree line and can see the crest of the mountains to the north.
