The National Science Foundation has signed a five-year, $34.5-million agreement with the University of Wisconsin-Madison to operate a unique telescope--a cubic kilometer in volume--buried in the Antarctic ice sheet between 1,400 meters and 2,400 meters deep. The collaborative agreement covers the cost of operating the IceCube Neutrino Observatory, located in the ice under the U.S. Amundsen-Scott South Pole Station. The observatory records the rare collisions of neutrinos, elusive sub-atomic...

About eight months before the NASA rover Curiosity touches down on Mars in August 2012, the mission's science measurements will begin much closer to Earth. The Mars Science Laboratory mission's Radiation Assessment Detector, or RAD, will monitor naturally occurring radiation that can be unhealthful if absorbed by living organisms. It will do so on the surface of Mars, where there has never before been such an instrument, as well as during the trip between Mars and Earth. RAD's measurements on...

Searching below the surface of Antarctica for the mysterious neutrino There's nothing like temperatures that can reach minus 100 degrees Fahrenheit to keep you on your toes. For engineers Erik Verhagen and Camille Parisel, working in Antarctica on a project appropriately called "IceCube" is both challenging and exciting. While there are ways to get used to the harsh climate, these experts have to be very resourceful to fix technical difficulties so far away from "civilization." "Whatever the...

The Alpha Magnetic Spectrometer-2 (AMS) destined for the International Space Station already is collecting cosmic ray signatures, even as it sits in a work stand at the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, said Prof. Samuel Ting, the principal investigator for the program. It "Ëœs not making any grand discoveries yet, since the particles it is picking up were stripped of some of their qualities when they passed through Earth's atmosphere. But...

Britain has officially opened the first station in a new global radio astronomy antenna network.  Dubbed LOFAR (Low Frequency Array), the European project will employ new digital techniques to simultaneously survey large portions of space. The new station in Britain joins similar installations in Sweden, France, Germany and the Netherlands. Scientists hope the new network will enable them to explore the formation of the very first stars in the universe. "In traditional arrays, you have...

In December 2010, IceCube -- the world's first kilometer-scale neutrino observatory, which is located beneath the Antarctic ice -- will finally be completed after two decades of planning. In an article in the AIP's Review of Scientific Instruments, Francis Halzen, the principal investigator of the IceCube project, and his colleague Spencer Klein of Lawrence Berkeley National Laboratory provide a comprehensive description of the observatory, its instrumentation, and its scientific...

One of the most complex space scientific instruments ever built, the Alpha Magnetic Spectrometer (AMS-02) arrived at the Kennedy Space Center in Florida on Friday, escorted by astronauts who will fly with it on the Space Shuttle in February 2011. The antimatter hunter AMS-02 began the first stage of its voyage to the International Space Station (ISS) from Geneva international airport, in Switzerland. During a ceremony organized by the European Organisation for Nuclear Research (CERN), the...

Though still under construction, the IceCube Neutrino Observatory  at the South Pole is already delivering scientific results "” including an early finding about a phenomenon the telescope was not even designed to study. IceCube captures signals of notoriously elusive but scientifically fascinating subatomic particles called neutrinos. The telescope focuses on high-energy neutrinos that travel through the Earth, providing information about faraway cosmic events such as supernovas...

Scientists leading an underground experiment to discover dark matter may be forced to relocate to a location even deeper below the Earth's surface, according to recent BBC News reports. Cosmic rays are to blame for disrupting the Cryogenic Dark Matter Search II (CDMS II) project, according to BBC Science Reporter Paul Rincon. The CDMS II experiments are currently taking place the Soudan mine in Minnesota, but could be relocated to the SNOLAB facility near Sudbury, Ontario, Canada. As said...

An international team including scientists from Princeton University has detected subatomic particles deep within the Earth's interior. The discovery could help geologists understand how reactions taking place in the planet's interior affect events on the surface such as earthquakes and volcanoes. Someday, scientists may know enough about the sources and flow of heat in the Earth to predict events like the recent volcanic eruption in Iceland. The finding, made by the Borexino Collaboration at...

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...
