Discovery Of Cosmic Neutrinos Signals New Era Of Astronomy

[ Watch the Video: Cosmic Neutrinos Observed By IceCube Observatory ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers working with the IceCube Neutrino Observatory in Antarctica have announced that they have, for the first time, observed 28 very high-energy particle events, leading them to conclude that "the era of neutrino astronomy has begun.” Cosmic neutrinos are nearly massless particles that stream to Earth at the speed of light from outside our solar system....

Flavor Changing Neutrinos

John P. Millis, PhD for redOrbit.com - Your Universe Online Protons, neutrons, and electrons – it is these tiny particles that make up most of the normal matter (that is, non-dark matter) in the Universe. Yet it is another, nearly massless particle that may turn out to be the most revealing about the nature of the cosmos. The neutrino plays a crucial role in nuclear processes such as fusion. But because of its small mass and neutral charge, it is very difficult to measure and study...

The behavior of some of the most elusive particles in the known universe can be simulated using three atoms in a lab, researchers at the Centre for Quantum Technologies (CQT) at the National University of Singapore have found. Principal Investigator Dimitris G. Angelakis and his group members Changsuk Noh and Blas Rodriguez-Lara have devised a scheme that uses the quantum states of three charged ions to simulate the 'oscillations' of neutrinos. The proposal is published in the March issue...

Relativity Corrections Could Explain Faster Than Light Neutrinos

When researchers at the European Center for Nuclear Research (CERN) observed what they believed to be sub-atomic particles moving faster than the speed of light, some believed that the discovery could challenge the very fundamental laws of the universe. It appears that those concerns were unfounded, as new research from scientists has shed light on exactly why CERN officials believe they witnessed beams of tiny particles of neutrinos traveling 60 nanoseconds (or 60 billionths of a second)...

Using one of the most sensitive neutrino detectors on the planet, an international team including physicists Laura Cadonati and Andrea Pocar at the University of Massachusetts Amherst are now measuring the flow of solar neutrinos reaching earth more precisely than ever before. The detector probes matter at the most fundamental level and provides a powerful tool for directly observing the sun´s composition. Pocar, Cadonati and colleagues report in the current issue of Physical Review...

On Monday, scientists in Europe said they have solved the case of the missing neutrinos, one of the enduring mysteries in the subatomic universe of particle physics. The researchers said the findings challenge core precepts of the so-called Standard Model of physics, and could have major implications for our understanding of matter in the universe. Neutrinos are electrically neutral particles that travel close to the speed of light. Physicists had observed for years that fewer neutrinos...

Oxford -- Astrophysicists from the Universities of Oxford and Rome have for the first time found evidence of ripples in the Universe's primordial sea of neutrinos, confirming the predictions of both Big Bang theory and the Standard Model of particle physics. Neutrinos are elementary particles with no charge and very little mass, which are extremely difficult to study due to their very weak interaction with matter. Yet pinning down the physical properties of neutrinos is of paramount...

Supernova 1987a -- Supernova 1987a was a supernova in the Large Magellanic Cloud, a nearby dwarf galaxy. It occurred approximately 50 kiloparsecs from Earth, the closest supernova since Supernova 1604, which occurred in the Milky Way itself. The light from the supernova reached Earth on February 23, 1987. Its brightness peaked in May with a magnitude of about 3 and slowly declined in the following months. It was modern astronomers' first opportunity to see a supernova up close....

Sudbury Neutrino Observatory -- The Sudbury Neutrino Observatory (SNO) is taking data that has provided revolutionary insight into the properties of neutrinos and the core of the sun. The detector, shown in the artist's conception below, was built 6800 feet under ground, in INCO's Creighton mine near Sudbury, Ontario. SNO is a heavy-water Cherenkov detector that is designed to detect neutrinos produced by fusion reactions in the sun. It uses 1000 tonnes of heavy water, on loan from...
