By Mark Vierthaler, Journal-World, Lawrence, Kan. Jul. 7--Members of Kansas University's physics department now have a new tool to help them determine what effect cosmic rays may have on mass extinction. While working with a group of other researchers, Alexander Krejci, Lawrence senior, developed a set of calculations that would allow researchers to study the effect a large number of rays could have on the Earth's atmosphere. Adrian Mellott, professor of astrobiophysics and cosmology,...

Mtron Storage Technology, a manufacturer of solid state drive products, has announced that their SSD will be used as the main 1Tb data storage for Antarctic Impulsive Transient Antenna, a project funded by NASA to research on high-energy cosmic ray from the South Pole, during the second experiment in December 2008. Antarctic Impulsive Transient Antenna (ANITA) is a radio telescope attached to NASA's stratospheric balloon to detect radio 'cherenkov', a frequency created by collision between...

Scientists in the U.K. have reported evidence that further refutes one theory of global climate change.In the heated debate over global warming, there is an opposing idea, called the cosmic ray theory, which contends that climate change is simply caused by cosmic rays coming from the sun.However, researchers at Lancaster University reported in the Institute of Physics journal that there has been no correlation between solar activity and the Earth's climate.Pioneered by Dr. Henrik Svensmark at...

Physicists revive bubble chamber technology to search for WIMPs Scientists working on the COUPP experiment at the Department of Energy's Fermi National Accelerator Laboratory today (February 14) announced a new development in the quest to observe dark matter. The Chicagoland Observatory for Underground Particle Physics experiment tightened constraints on the "spin-dependent" properties of WIMPS, weakly interacting massive particles that are candidates for dark matter. Their results, combined...

By working in synergy with a ground-based telescope array, the joint Japanese Aerospace Exploration Agency (JAXA)/NASA Suzaku X-ray observatory is shedding new light on some of the most energetic objects in our galaxy, but objects that remain shrouded in mystery. These cosmic powerhouses pour out vast amounts of energy, and they accelerate particles to almost the speed of light. But very little is known about these sources because they were discovered only recently. "Understanding these...

SAN FRANCISCO--New observations from the edge of our solar system show what scientists have suspected for several years: The solar system is squashed. The edge of the solar system is roughly where the solar wind runs up against thin gas found between the stars in the rest of the Milky Way. This "wind," actually a thin gas of electrically charged particles, blows outward in all directions from the sun at between 1 million and 2 million mph, forming a bubble called the...

GREENBELT, Md. - NASA's Gamma-ray Large Area Space Telescope (GLAST) has arrived at the Naval Research Laboratory (NRL) in Washington for its final round of testing. The GLAST spacecraft has successfully completed two of its three environmental tests at the prime contractor, General Dynamics Advanced Information Systems in Gilbert, Ariz. These tests included exposure to extreme vibrations and electromagnetic fields. "We've completed two of the big three tests, and now we're going to the NRL...

GREENBELT, Md. -- Recent observations from NASA and Japanese X-ray observatories have helped clarify one of the long-standing mysteries in astronomy -- the origin of cosmic rays. Outer space is a vast shooting gallery of cosmic rays. Discovered in 1912, cosmic rays are not actually rays at all; they are subatomic particles and ions (such as protons and electrons) that zip through space in all directions at near-light speed, with energies tens of thousands of times greater than particles...

Ancient explorers set sail expecting to encounter dragons on the world's unknown oceans. NASA's twin Voyager spacecraft are searching for dragons of a different sort as they enter the boundary of our solar system "“ cosmic "dragons" that breathe a strange fire of high-speed atomic fragments called cosmic rays. Just as mythical dragons were expected to inhabit stormy seas, these cosmic dragons could be found among turbulent magnetic fields powered by the colliding winds of stars,...

In the last year space agencies in the United States, Europe, China, Japan and India have announced their intention to resume human exploration of the Solar system, beginning with the Moon and perhaps ultimately moving on to Mars. But travel beyond the immediate vicinity of the Earth carries significant risks for astronauts, not the least of which is the exposure to sometimes high levels of radiation. Now a team of scientists at the Rutherford Appleton Laboratory are set to construct an...

The IceCube Neutrino Observatory is a neutrino telescope that is currently being built at the Amundsen-Scott South Pole Station. IceCube is being constructed in deep Antarctic ice by deploying thousands of PMTs (photomultiplier tubes) at depths of 4750 to 8000 feet. These spherical optical sensors are deployed on strings of sixty modules each, into holes melted by hot water drilling. Since 2005, 59 strings have been deployed and installation is expected to be complete by 2011. The strings are...

Gamma-Ray Astronomy -- Gamma-ray astronomy is the astronomical study of gamma rays. Long before experiments could detect gamma rays emitted by cosmic sources, scientists had known that the universe should be producing these photons. Work by Feenberg and Primakoff in 1948, Hayakawa and Hutchinson in 1952, and, especially, Morrison in 1958 had led scientists to believe that a number of different processes which were occurring in the universe would result in gamma-ray emission. These...
