Satellite debris watched closely

Satellite debris watched closely Marcia Dunn ASSOCIATED PRESS Thursday, February 12, 2009 CAPE CANAVERAL, Fla. (AP) — Scientists are keeping a close eye on orbital debris created when two communications satellites — one American, the other Russian — smashed into each other hundreds of miles above the Earth. NASA said it will take weeks to determine the full magnitude of the unprecedented crash and whether any other satellites or even the Hubble Space Telescope are threatened. The collision, which occurred nearly 500 miles over Siberia

Odd Planet Reaches Searing 1,200 Degrees

Odd Planet Reaches Searing 1,200 Degrees Seth Borenstein, Associated Press Astronomers have found a planet with a galactic case of hot flashes. In just six hours, this planet four times the size of Jupiter heats up by more than 1,200 degrees, according to a study published in Thursday’s issue of the journal Nature. “It’s the first observation of changing weather” on a planet outside our solar system, said study author Gregory Laughlin, an astronomy professor at the University of California at Santa Cruz. He used

Scientists Not So Sure ‘Doomsday Machine’ Won’t Destroy World Wednesday, January 28, 2009 By Paul Wagenseil Still worried that the Large Hadron Collider will create a black hole that will destroy the Earth when it’s finally switched on this summer? Three physicists have reexamined the math surrounding the creation of microscopic black holes in the Switzerland-based LHC, the world’s largest particle collider, and determined that they won’t simply evaporate in a millisecond as had previously been predicted.

Earth’s Magnetic Field Changes Climate

Earth’s Magnetic Field Changes Climate Jan. 13, 2009 The Earth’s climate has been significantly affected by the planet’s magnetic field, according to a Danish study published Monday that is unlikely to challenge the notion that human emissions are largely responsible for global warming. “Our results show a strong correlation between the strength of the Earth’s magnetic field and the amount of precipitation in the tropics,” one of the two Danish geophysicists behind the study, Mads Faurschou Knudsen of the geology department at Aarhus University in

Mars Methane Found, Raising Possibility of Life

• February, 2009

Mars Methane Found, Raising Possibility of Life Irene Klotz, Discovery News Scientists have discovered rich plumes of methane on Mars that not only disappear quickly, but are replenished by unknown sources that could be biological or geochemical in origin. “Either way, it’s very interesting,” planetary scientist Michael Mumma, with NASA’s Goddard Space Flight Center in Greenbelt, Md., told Discovery News. “Mars is not a dead planet.” Mumma and colleagues used infrared spectrometers on three ground-based telescopes to monitor concentrations of methane in Mars’ atmosphere over

Do we live in a holographic universe?

Do we live in a holographic universe? by Marcus Chown 15 January 2009 DRIVING through the countryside south of Hanover, it would be easy to miss the GEO600 experiment. From the outside, it doesn’t look much: in the corner of a field stands an assortment of boxy temporary buildings, from which two long trenches emerge, at a right angle to each other, covered with corrugated iron. Underneath the metal sheets, however, lies a detector that stretches for 600 metres. For the past seven years, this
