    Reuters) - Underground sensors have detected excessive radiation levels inside a nuclear waste storage site deep below New Mexico's desert, but no workers have been exposed and there was no risk to public health, U.S. Department of Energy officials said on Sunday. An air-monitoring alarm went off at 11:30 p.m. local time Friday indicating unsafe concentrations of radiation inside the Waste Isolation Pilot Plant in what DOE officials said appeared to be the first such mishap since the facility opened in 1999. As of Sunday, the source of the high radiation readings had yet to be determined, and a plan...

    Network of stations with seismometers and air pressure sensors detected the blast waves A network of seismographic stations recorded spectacular signals from the blast waves of the meteor that landed near Chelyabinsk, Russia, as the waves crossed the United States. The National Science Foundation- (NSF) supported stations are used to study earthquakes and the Earth's deep interior. While thousands of earthquakes around the globe are recorded by seismometers in these stations--part of the permanent Global Seismographic Network (GSN) and EarthScope's temporary Transportable Array (TA)--signals from large meteor impacts are far less common. The meteor explosion near Chelyabinsk on Feb. 15,...

    LOS ANGELES – Air pollution regulators in Southern California say they have not detected increased levels of radiation from the damaged Japanese nuclear reactors. The South Coast Air Quality Management District said Friday radiation measured at its three sites are not higher than typical levels.

    A ball of gas more massive than a billion suns is hurtling like an enormous comet through the interior of a distant galaxy cluster. The massive structure is held together by mysterious dark matter, astronomers said today, but it is steadily breaking apart and becoming fuel for new stars. "This is likely a massive building block being delivered to one of the largest assembly of galaxies we know," said study team member Alexis Finoguenov of the University of Maryland, Baltimore County. The finding is detailed in the June 6 issue of Astrophysical Journal. Great ball of fire The gas blob...

    Tremors deep inside the Earth are usually produced by magma flowing beneath volcanoes, but a new study suggests they can also be produced by the shifting and sliding of tectonic plates. Scientists have recorded vibrations from underground tremors at a geologic observatory along the San Andreas Fault, an 800 mile scar in the earth that runs through California. The fault marks the boundary between the Pacific Tectonic Plate and the North American Plate. Tectonic plates are large pieces of the Earth's crust that bump and grind like chunks of sea ice floating atop the ocean. The Earth's surface is made...
  • Glow of alien planets detected for first time

    SAN DIEGO - The glow of planets outside our solar system have been spotted in the first direct detections of light emitted by alien worlds. The two planets were detected in infrared light, an emission of heat that is not visible to the human eye. There are no conventional photographs, but astronomers are ecstatic nonetheless. The gas giant worlds, each around a different star, were discovered previously by noting the gravitational wobbles they induce in their host stars -- an indirect method. Both are roughly Jupiter-sized and hot, orbiting very close to their stars. Each completes a "year" in less...

    Searchers 'may have detected flight recorder' Searchers hunting for the wreckage of a charter jet that crashed into the Red Sea have detected a signal that could be the plane's black box flight data recorder. The signal was detected by a radar on a robotic arm used by searchers in the area where Flash Airlines' Flight FSH604 crashed on Saturday. "It's a positive sign but nothing conclusive," said a French Embassy official, on condition of anonymity. There was no indication of how deep the signal was coming from. Experts had said the deep waters would slow recovery efforts. Most of...

    Sunlight's gentle nudge on asteroids detected 19:00 04 December 03 NewScientist.com news service Astronomers have detected the delicate force of sunlight on an asteroid's orbit for the first time. The long-predicted effect has been blamed for propelling some asteroid fragments from the Solar System's main asteroid belt into the region near Earth, where they can threaten the planet. But its subtle action on asteroid orbits has been difficult to measure with optical telescopes. Instead, Steve Chesley, Steve Ostro and colleagues at NASA's Jet Propulsion Lab in Pasadena, California, used the radar range finder at Arecibo in Puerto Rico. They used...
