A pair of NASA probes has discovered a previously unknown ring of radiation blanketing the Earth, upending a long-standing scientific theory about how charged particles coalesce around the planet, scientists reported Thursday. Just four days after the twin Radiation Belt Storm Probes were launched in August, NASA scientists looked on in amazement as instruments revealed a third belt of high-energy particles between the planet's inner and outer radiation belts, known as the Van Allen belts.

Mike T. Chou of Caltech is one of 20 college juniors to receive the Time College Achievement Award sponsored by Time magazine. Chou of Torrance, who will receive $3,000, wrote a software program that enabled him to study the acceleration process of solar flares. His subsequent discoveries have "given astrophysicists new information in their struggle to understand how the sun actually works," Time officials said.

Hundreds of West German homing pigeons are flying aimlessly around, and pigeon fanciers here suspect gigantic gas eruptions on the surface of the sun may be to blame. The West Germany Homing Pigeon Federation in this city said that 40% of 4,000 birds that were released last weekend in Denmark have failed to make it home to their various lofts in West Germany. The mystery could be explained by solar flares reported to have erupted Sunday and Monday, bombarding the Earth with unusual radiation.

After five launch attempts were scrubbed because of high winds, a Navy satellite built to take precise wind speed measurements blasted into space at 6:19 a.m. Monday from Vandenberg Air Force Base. The satellite successfully separated from its launch vehicle, an Air Force Titan II missile, about an hour later while flying over Kenya. The Navy's Windsat instrument will measure wind speeds near the surface of the ocean to improve weather forecasts.

Solar flares emitted by the sun in its youth may have helped newly developed planets survive by pushing them away from the sun's powerful gravity well, researchers said Wednesday. Looking through the Chandra X-ray Observatory, which NASA launched into orbit in 1999, the astronomers focused on a cluster of young stars in the Orion Nebula, 1,500 light-years from Earth.

Caltech astronomers have detected the first sunspot of a new sunspot cycle, marking the end of the sun's quiescent period and the beginning of a new surge of activity. The spot was observed Aug. 12 by Hal Zirin and his colleagues at Big Bear Solar Observatory. Sunspots--dark areas on the sun's surface associated with strong magnetic fields, solar flares and disruptions of radio communications on Earth--have an 11-year cycle marked by increasing activity followed by a slow decline into quiescence.

One of the strongest geomagnetic storms since 1976 disrupted communications across much of the northern United States on Saturday, a spokesman at the National Oceanic and Atmospheric Administration said. The disruption of the Earth's normal magnetic field meant problems for satellites, radios and aircraft, but also meant a "northern lights" display much farther south than usual, a spokesman at NOAA's Space Environment Services Center said.

The orbit of Solar Max, a 5,000-pound satellite that collected information on solar flares for nine years, has deteriorated to the point that the spacecraft should crash back to Earth late this week, NASA said today. Most of the craft will burn up in the atmosphere, but about a dozen pieces weighing 3 to 5 pounds each, plus one piece weighing about 100 pounds, are expected to come back down to Earth. The debris could hit anywhere on Earth from 28 degrees north to 28 degrees south of the Equator.

There's a rare hybrid solar eclipse coming on Sunday, and no matter where you are in the world, you will be able to see it - thanks to the Internet. If you live on the Eastern Seaboard of the United States, in parts of southern Europe or anywhere in Africa, then you can enjoy this eclipse firsthand with a little planning and the proper viewing glasses , of course. If you live in Los Angeles or somewhere that is not any of the places mentioned above, then you will have to turn to your computer if you want to watch the eclipse live. Luckily, Paul Cox, an astronomer at the online observatory Slooh.com, is shepherding a telescope and other equipment to a remote spot in Kenya, where he plans to live-stream the total eclipse to viewers across the world.
