Dark Matter Results From LUX Confirmed After Recalibration - WIMPs Still Not Detected
2014-02-21 08:47:17

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Dark matter research, like all experiments involving particle and astrophysical detections, relies on sorting out the desired events (the source events) from the noise (the background events). Since the interactions occur at a quantum level, the statistical process of sorting through the data is laborious, but also, more importantly, relies on your ability to calibrate and understand the instrument. Back in October the Large...

Pamela Fleming, Executive Secretary of the Institute for Basic Research, Florida, announces the apparent detection of antimatter galaxies, antimatter asteroids and antimatter cosmic rays by the Italian-American scientists R. M. Santilli via a new refractive telescope with concave lenses (http://www.santilli-foundation.org/Detect-Ant-Galaxies.php). Palm Harbor, Florida, (PRWEB) February 18, 2014 Pamela Fleming, Executive Secretary of the Institute for Basic Research, Florida, announces the...

Lead Ingots From Shipwrecks Being Used To Hunt For Dark Matter
2013-12-02 08:18:12

Gerard LeBlond for redorbit.com - Your Universe Online A Roman vessel carrying ingots of lead, which was removed from the Sierra of Cartagena, sank more than two thousand years ago off the coast of Sardinia. Now, more than a hundred of these lead bricks have been used to build the ‘Cryogenic Underground Observatory for Rare Events’ (CUORE), an advanced detector of almost weightless subatomic particles (neutrinos) and is located at the Gran Sasso National Laboratory in Italy....

Axion Search For Dark Matter
2013-11-07 08:36:41

April Flowers for redOrbit.com - Your Universe Online A research team at the University of Washington, led by Professor Leslie Rosenberg, is hunting for a theorized but never-before-seen elementary particle called an axion. The researchers will use the recently retooled, extremely sensitive detector that is currently in a testing and shakeout phase at UW's Center for Experimental Nuclear Physics Astrophysics. Physicists in the late 1970s first hypothesized the axion as a solution to a...

LUX Dark Matter Detector Finds Nothing Yet
2013-10-30 13:49:42

Brett Smith for redOrbit.com - Your Universe Online Just three months into its operation the Large Underground Xenon (LUX) experiment is already the most sensitive dark matter detector in the world, according to scientists from Brown University. “LUX is blazing the path to illuminating the nature of dark matter,” said Rick Gaitskell, professor of physics at Brown University and project spokesperson. The detector sits over a mile below the Sanford Underground Research Facility in...

Experiment Looks For Dark Matter Particle

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...

Space Weather Impacts Pilots And Airline Passengers
2013-10-27 06:19:50

[ Watch the Video: Pilots And Passengers Absorb Cosmic Rays And Radiation ] redOrbit Staff & Wire Reports - Your Universe Online Thanks to space weather, airline pilots absorb approximately as much radiation over the course of a year as a nuclear power plant employee, NASA officials revealed on Friday. In fact, according to the US space agency, pilots are classified as “occupational radiation workers” by the Federal Aviation Administration (FAA) because they fly at heights...

Carbon Capture Monitoring With Cosmic Rays
2013-09-15 04:27:27

redOrbit Staff & Wire Reports - Your Universe Online Researchers from Durham University in the UK are looking towards the stars for a method to reduce costs associated with carbon capture and storage (CCS) – a process that could potentially mitigate contribution of fossil fuel emissions to global warming and ocean acidification. According to BBC News science reporter Simon Redfern, CCS involves capturing carbon dioxide (CO2) from fuel as it is burned at a power station. That CO2...

Cosmic Rays Influence Cloud Formation

John P. Millis, PhD for redOrbit.com - Your Universe Online Little more than a century ago Austrian-American physicist Victor Hess established that out in the Universe charged particles are accelerated to very high energies, some eventually making their way to Earth. While much of the research into the curiously named cosmic rays – they, in fact, are not rays at all – has focused on determining their origins, scientists have also devoted considerable effort to studying their effects on...

Cosmic Rays Origins

[ Listen To The redOrbit.com Podcast: The Mystery Of The Origins Of Cosmic Rays ] John P. Millis, PhD for redOrbit.com - Your Universe Online Streaming across the Universe are high-energy charged particles, known as cosmic rays. They move through space, interacting with our galactic magnetic field, deflecting in every possible direction. Eventually these fast-moving particles may impact the Earth’s atmosphere. For more than 100 years astronomers have been aware of their existence,...

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....

Massive Compact Halo Object (MACHO) -- Massive compact halo objects, or MACHOs, are a type of astronomical body proposed as one possible explanation for the presence of dark matter in galactic halos. A MACHO is a small chunk of normal baryonic matter, far smaller than a star, which drifts through interstellar space unassociated with any solar system. Since MACHOs would not emit any light of their own, they would be very hard to detect. Recent work has suggested that MACHOs are not...

Cosmic Rays -- Cosmic Rays. Cosmic rays are energetic particles that are found in space and filter through our atmosphere. Cosmic rays have interested scientists for many different reasons. They come from all directions in space, and the origination of many of these cosmic rays is unknown. Cosmic rays were originally discovered because of the ionozation they produce in our atmosphere. Cosmic rays also have an extreme energy range of incident particles, which have allowed physicists to...
