Testing Einstein's Theory Of Relativity Through Cosmic Microwave Measurements
2014-05-14 08:27:34

April Flowers for redOrbit.com - Your Universe Online What do you get when you combine polarized radiation with Einstein's theory of general relativity? According to a group of astrophysicists at UC San Diego, you just might get more accurate estimates for the mass of ghostly subatomic particles known as neutrinos. The study, published in Physical Review Letters, measures the distortions in polarized radiation from the early universe and demonstrates that these ancient microwaves can...

Syracuse University Plays Key Role In Search For Elusive Dark Matter
2014-04-11 13:31:00

By Rob Enslin, Syracuse University Physicist Richard Schnee hopes to find traces of dark matter by studying particles with low masses and interaction rates, some of which have never been probed before. The ongoing search for invisible dark matter is the subject of a recent article involving physicists from Syracuse University's College of Arts and Sciences. Research by Richard Schnee, assistant professor of physics, is referenced in Symmetry magazine, a joint publication of the...

Reconstructing The Death Of Supernovae In 3D Offers New Insights
2014-03-18 13:29:42

Lee Rannals for redOrbit.com - Your Universe Online An astrophysicist has created a new three-dimensional model that provides new insight into the death throes of supernovae. The model, created by W. David Arnett, Regents Professor of Astrophysics at the University of Arizona, is the first to represent the start of a supernova collapse in 3D. It shows how the turbulent mixing of elements inside the dying stars causes them to expand, contract and spit out matter before exploding....

Turbulent Mixing Inside Stars Causes them to Expand, Contract, Eject and Explode, According to 3-D Model Described in the Journal "AIP Advances" WASHINGTON, March 18, 2014 /PRNewswire-USNewswire/ -- A powerful, new three-dimensional model provides fresh insight into the turbulent death throes of supernovas, whose final explosions outshine entire galaxies and populate the universe with elements that make life on Earth possible....

Massive Neutrinos Help Solve A Cosmological Conundrum
2014-02-10 09:36:04

University of Manchester Scientists have solved a major problem with the current standard model of cosmology identified by combining results from the Planck spacecraft and measurements of gravitational lensing in order to deduce the mass of ghostly sub-atomic particles called neutrinos. The team, from the universities of Manchester and Nottingham, used observations of the Big Bang and the curvature of space-time to accurately measure the mass of these elementary particles for the first...

High-energy Neutrinos Recorded By IceCube Particle Detector In Antarctica
2013-12-02 09:48:39

SPIE Achievement heralds 'the dawn of a new age of astronomy' Scientists at a massive underground particle detector in Antarctica called the IceCube South Pole Neutrino Observatory have detected high-energy neutrinos, ideal for the future of "extreme astronomy" because they can be used to detect the sources of cosmic rays and provide information about our universe's most violent and least-understood phenomena. "This is the first indication of very high-energy neutrinos coming from...

Neutron Star Mystery Heats Up
2013-12-02 04:34:10

redOrbit Staff & Wire Reports - Your Universe Online New research appearing in the latest edition of the journal Nature is casting doubts on currently accepted theories has to how the surface of a neutron star heats itself up. Neutron stars are super-dense stars that form once a large star explodes, causing the core to collapse upon itself. Scientists had long believed that nuclear reactions within the crust contributed to the heating of the star’s surface, but Michigan State...

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....

Experiment Looks For Dark Matter Particle
2013-10-29 08:16:46

John P. Millis, PhD for redOrbit.com - Your Universe Online As we peer into the darkness of space we find stars, planets, nebulae, and gas clouds. These objects are all made of normal matter – protons, neutrons, electrons, and other elementary particles. But it is the matter that we don’t see that has confounded astronomers for decades. An estimated 80 percent of the stuff that makes up the Universe does not interact electromagnetically. This aptly named dark matter is...

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...

WIMP -- In astronomy, WIMPs, or weakly interacting massive particles, figure into one explanation of the dark matter problem. The particles are called "weakly interacting" because they seem not to have much interaction with normal matter (electrons, protons, and neutrons) other than gravitational attraction (thus "massive"). Assuming that there are Weakly Interacting Massive Particles, these particles would then fall out of equilibrium with the universe when they are non-relativistic....

Solar Radiation -- Solar radiation is radiant energy emitted by the sun due to nuclear fusion reactions. Fusion is the process whereby stars produce huge quantities of energy from the fusion of hydrogen or helium, in one of the most efficient processes of energy generation. The radiation referred to is usually electromagnetic energy, particularly infrared radiation, visible light, and ultraviolet. Some stars are known to emit radiation of other wavelengths. Solar neutrinos are a...

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...
