(PhysOrg.com) -- A thin rain of charged particles continually bombards our atmosphere from outer space. The mysterious particles were first detected 100 years ago but until 10 years ago when a new type of telescope began to come online physicists weren't sure where the "cosmic rays" came from or how they were generated. They suspected the particles were accelerated by supernova shockwaves, but suspicions aren't proof. http://www.physorg.com/news179427195.html Space & Earth Mon, 07 Dec 2009 18:30:01 EST news179427195 (PhysOrg.com) -- An international collaboration that includes scientists from the University of Delaware's Bartol Research Institute in the Department of Physics and Astronomy has discovered very-high-energy gamma rays in the Cigar Galaxy (M82), a bright galaxy filled with exploding stars 12 million light years from Earth. http://www.physorg.com/news176391501.html Space & Earth Mon, 02 Nov 2009 13:50:01 EST news176391501 New research suggests that there is plenty of oxygen available in the subsurface ocean of Europa to support oxygen-based metabolic processes for life similar to that on Earth. In fact, there may be enough oxygen to support complex, animal-like organisms with greater oxygen demands than microorganisms. http://www.physorg.com/news174918239.html Space & Earth Fri, 16 Oct 2009 13:24:45 EST news174918239 From 10 to 17 October 2009, in France, Italy, Spain and many other countries, astroparticle physicists will meet the public to reveal some of the most exciting mysteries of the Universe. Within the first European Week of Astroparticle Physics, they will organise about 50 events all over Europe: open days, talks for the general public, exhibitions… http://www.physorg.com/news173713862.html Space & Earth Fri, 02 Oct 2009 15:30:01 EST news173713862 (PhysOrg.com) -- Planning a trip to Mars?

And now it's possible that PAMELA might have already spotted dark matter. http://www.physorg.com/news170436249.html Physics Tue, 25 Aug 2009 16:24:43 EST news170436249 NASA's space shuttle program is winding down. With only about half a dozen more flights, shuttle crews will put the finishing touches on the International Space Station (ISS), bringing to an end twelve years of unprecedented orbital construction. The icon and workhorse of the American space program will have finished its Great Task. http://www.physorg.com/news169739995.html Physics Mon, 17 Aug 2009 15:30:01 EST news169739995 Billions of tonnes of water droplets vanish from the atmosphere, as if by magic, in events that reveal in detail how the Sun and the stars control our everyday clouds. Researchers of the National Space Institute in the Technical University of Denmark (DTU) have traced the consequences of eruptions on the Sun that screen the Earth from some of the cosmic rays - the energetic particles raining down on our planet from exploded stars. http://www.physorg.com/news168353215.html Space & Earth Sat, 01 Aug 2009 14:10:01 EST news168353215 (PhysOrg.com) -- NASA's Fermi Gamma-ray Space Telescope is making some exciting discoveries about cosmic rays and the Large Area Telescope aboard Fermi is the tool in this investigation.

They show in a paper published today on Science Express that cosmic rays from our galaxy are very efficiently accelerated in the remnants of exploded stars. http://www.physorg.com/news165159142.html Space & Earth Thu, 25 Jun 2009 14:32:53 EST news165159142 (AP) -- Far below the Black Hills of South Dakota, crews are building the world's deepest underground science lab at a depth equivalent to more than six Empire State buildings - a place uniquely suited to scientists' quest for mysterious particles known as dark matter. http://www.physorg.com/news164915655.html Physics Mon, 22 Jun 2009 18:54:55 EST news164915655 The Phantom Torso is back, and he has quite a story to tell. He's an armless, legless, human-shaped torso, a mannequin that looks like he's wrapped in a mummy's bandages. Scientists at the European Space Agency call him Matroshka, and like his NASA counterpart Fred, this mannequin is an intrepid space traveler. Now that he's spent four months on the International Space Station, scientists are learning about the space radiation that Matroshka endured. http://www.physorg.com/news162746684.html Space & Earth Thu, 28 May 2009 16:25:53 EST news162746684 (PhysOrg.com) -- University of Delaware researchers in Sweden have launched a giant balloon taller than a football field that is now flying at the edge of space to collect data on cosmic rays -- the most super-charged particles in the universe. http://www.physorg.com/news162143391.html Space & Earth Thu, 21 May 2009 19:35:59 EST news162143391 With the U.S. Congress beginning to consider regulations on greenhouse gases, a troubling hypothesis about how the sun may impact global warming is finally laid to rest. http://www.physorg.com/news161268877.html Space & Earth Mon, 11 May 2009 13:54:56 EST news161268877 (Physorg.com) -- Since its launch last June, NASA's Fermi Gamma-ray Space Telescope has discovered a new class of pulsars, probed gamma-ray bursts and watched flaring jets in galaxies billions of light-years away. Today at the American Physical Society meeting in Denver, Colo., Fermi scientists revealed new details about high-energy particles implicated in a nearby cosmic mystery. http://www.physorg.com/news160659605.html Space & Earth Mon, 04 May 2009 12:41:03 EST news160659605 (PhysOrg.com) -- Researchers at North Carolina State University have used a mathematical model that allows them to get a clearer picture of the galaxy's youngest supernova remnant by correcting for the distortions caused by cosmic dust. Their new data provides evidence that this remnant is from a type Ia supernova - the explosion of a white dwarf star - and raises questions about the ways in which magnetic fields affect the generation of the remnant's cosmic ray particles. http://www.physorg.com/news159639776.html Space & Earth Wed, 22 Apr 2009 17:23:25 EST news159639776 (PhysOrg.com) -- Space seems exotic, forbidding, and remote, but imagine trying to survive winter without a heated shelter or warm clothing. Our ancestors developed these technologies because they needed room to grow; without them, we would still be confined to narrow areas along the equator, but with them, we could live anywhere in the world. With the right technology, space is just another place for people to live. http://www.physorg.com/news159195930.html Space & Earth Fri, 17 Apr 2009 14:06:14 EST news159195930 (PhysOrg.com) -- Twin NASA spacecraft have provided scientists with their first view of the speed, trajectory, and three-dimensional shape of powerful explosions from the sun known as coronal mass ejections, or CMEs. This new capability will dramatically enhance scientists' ability to predict if and how these solar tsunamis could affect Earth. http://www.physorg.com/news158940323.html Space & Earth Tue, 14 Apr 2009 15:06:02 EST news158940323 European astronomers said on Wednesday that an anomalous energy signal detected by an orbiting satellite could be a telltale of the enigmatic substance known as dark matter. http://www.physorg.com/news157814632.html Physics Wed, 01 Apr 2009 14:24:17 EST news157814632 (PhysOrg.com) -- 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. http://www.physorg.com/news151775496.html Space & Earth Wed, 21 Jan 2009 15:52:16 EST news151775496 (PhysOrg.com) -- A new study supports earlier findings by stating that changes in cosmic rays most likely do not contribute to climate change. http://www.physorg.com/news148751093.html Space & Earth Wed, 17 Dec 2008 15:44:53 EST news148751093 A Los Alamos National Laboratory cosmic-ray observatory has seen for the first time two distinct hot spots that appear to be bombarding Earth with an excess of cosmic rays.

This current state of the Sun could reduce the natural shielding that envelops our Solar System. http://www.physorg.com/news141397124.html Space & Earth Tue, 23 Sep 2008 13:58:44 EST news141397124 (PhysOrg.com) -- 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 next 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. http://www.physorg.com/news139810863.html Physics Fri, 05 Sep 2008 05:21:03 EST news139810863
