British scientists say they've detected cosmic rays reaching an underground detector that reflect major weather events occurring in the Earth's stratosphere. The researchers said the cosmic-rays detected half a mile underground in a unused U.S. iron mine can be used to determine major weather events occurring 20 miles above the Earth. The researchers from the United Kingdom's National Center for Atmospheric Science and the Science and Technology Facilities Council said the study shows how the...

Cosmic-rays detected half a mile underground in a disused U.S. iron-mine can be used to detect major weather events occurring 20 miles up in the Earth's upper atmosphere, a new study has revealed. Published in the journal Geophysical Research Letters and led by scientists from the UK's National Centre for Atmospheric Science (NCAS) and the Science and Technology Facilities Council (STFC), this remarkable study shows how the number of high-energy cosmic-rays reaching a detector deep...

NASA and the National Science Foundation have successfully launched and demonstrated a newly designed super pressure balloon prototype that may enable a new era of high-altitude scientific research. The super-pressure balloon ultimately will carry large scientific experiments to the brink of space for 100 days or more. This seven-million-cubic-foot super-pressure balloon is the largest single-cell, super-pressure, fully-sealed balloon ever flown. When development ends, NASA will have a 22...

An international team of scientists is working under Antarctica's snow-covered surface to build the world's largest neutrino telescope. The telescope -- called IceCube -- will occupy a cubic kilometer of Antarctica when it is completed in 2011, said University of Delaware Professor Thomas Gaisser, one of the project's lead scientists. IceCube will provide new information about some of the most violent and far-away astrophysical events in the cosmos, said Gaisser, who is managing the...

It's 40 degrees F below zero (with the wind chill) at the South Pole today. Yet a research team from the University of Delaware is taking it all in stride. The physicists, engineers and technicians from the University of Delaware's Bartol Research Institute are part of an international team working to build the world's largest neutrino telescope in the Antarctic ice, far beneath the continent's snow-covered surface. Dubbed "IceCube," the telescope will occupy a cubic kilometer of Antarctica...

Take a gold sample the size of the head of a push pin, shoot a laser through it, and suddenly more than 100 billion particles of anti-matter appear. The anti-matter, also known as positrons, shoots out of the target in a cone-shaped plasma "jet." This new ability to create a large number of positrons in a small laboratory opens the door to several fresh avenues of anti-matter research, including an understanding of the physics underlying various astrophysical phenomena such as black holes and...

A team of researchers in Canada have made a bold stride in the struggle to detect dark matter. The PICASSO collaboration has documented the discovery of a significant difference between the acoustic signals induced by neutrons and alpha particles in a detector based on superheated liquids. Since neutron induced signals are very similar to dark matter induced signals, this new discovery, published today, Thursday, 16 October, in the New Journal of Physics, could lead to improved background...

Data from the Ulysses spacecraft, a joint NASA-European Space Agency mission, show the sun has reduced its output of solar wind to the lowest levels since accurate readings became available. The sun's current state could reduce the natural shielding that envelops our solar system. "The sun's million mile-per-hour solar wind inflates a protective bubble, or heliosphere, around the solar system. It influences how things work here on Earth and even out at the boundary of our solar system where...

A new report published on Friday, 5 September, provides the most comprehensive evidence available to confirm that the Large Hadron Collider (LHC)'s switch-on, due on Wednesday this week, poses no threat to mankind. Nature's own cosmic rays regularly produce more powerful particle collisions than those planned within the LHC, which will enable nature's laws to be studied in controlled experiments. The LHC Safety Assessment Group have reviewed and updated a study first completed in 2003, which...

WASHINGTON -- NASA's newest observatory, the Gamma-Ray Large Area Space Telescope, or GLAST, has begun its mission of exploring the universe in high-energy gamma rays. The spacecraft and its revolutionary instruments passed their orbital checkout with flying colors. NASA announced today that GLAST has been renamed the Fermi Gamma-ray Space Telescope. The new name honors Prof. Enrico Fermi (1901 - 1954), a pioneer in high-energy physics. "Enrico Fermi was the first person to suggest how...

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...
