Massive solar storm to hit Earth in 2012 with 'force of 100m bombs' - Yahoo! India News SDO helps measure magnetic fields on the sun's surface (PhysOrg.com) -- Science nuggets are a collection of early science results, new research techniques, and instrument updates that further our attempt to understand the sun and the dynamic space weather system that surrounds Earth. A subset of data that helps map out the sun's magnetic fields was recently released from the Solar Dynamics Observatory (SDO). Observations that measure the strength and direction of magnetic fields on the solar surface -- known as vector magnetograms -- play a crucial role in understanding how those fields change over time and trigger giant eruptions off the surface of the sun such as solar flares and coronal mass ejections (CMEs). Collecting the information needed to make vector magnetograms is one of several tasks performed by SDO's Helioseismic and Magnetic Imager (HMI), an instrument led by a team at Stanford University. HMI relies on interpreting the way light is affected as it travels through the fields in order to measure them from afar.
Southwest Research Institute (SwRI) 2014 News Release - IBEX research shows the influence of the galactic magnetic field extends well beyond our solar system For immediate release San Antonio — Feb. 13, 2014 — In a report published today, new research suggests the enigmatic “ribbon” of energetic particles discovered at the edge of our solar system by NASA’s Interstellar Boundary Explorer (IBEX) may be only a small sign of the vast influence of the galactic magnetic field. IBEX researchers have sought answers about the ribbon since its discovery in 2009. Comprising primarily space physicists, the IBEX team realized that the galactic magnetic field wrapped around our heliosphere — the giant “bubble” that envelops and protects our solar system — appears to determine the orientation of the ribbon and the placement of energetic particles measured in it. The cosmic ray physics team measured super-high-energy particles to study anisotropies, or the unequal distribution of particles as they arrive from various directions. “The teraelectronvolt (TeV) particles measured by the team are incredible,” says Dr.

The strange case of solar flares and radioactive elements (8/25/2010) It's a mystery that presented itself unexpectedly: The radioactive decay of some elements sitting quietly in laboratories on Earth seemed to be influenced by activities inside the sun, 93 million miles away. Is this possible? Researchers from Stanford and Purdue University believe it is. But their explanation of how it happens opens the door to yet another mystery. There is even an outside chance that this unexpected effect is brought about by a previously unknown particle emitted by the sun. "That would be truly remarkable," said Peter Sturrock, Stanford professor emeritus of applied physics and an expert on the inner workings of the sun. The story begins, in a sense, in classrooms around the world, where students are taught that the rate of decay of a specific radioactive material is a constant. Random numbers But that assumption was challenged in an unexpected way by a group of researchers from Purdue University who at the time were more interested in random numbers than nuclear decay.
Russia wants to build Moonbase Alpha The Russian Space Agency (Roscosmos) has suffered a string of embarrassing space-related debacles over the past few months. The most notable failures? The infamous loss of the Phobos-Grunt probe slated to survey a Martian moon, the disintegration of an unmanned ISS-bound space freighter and several satellite crashes. But Roscosmos chief Vladimir Popovkin doesn’t appear to be particularly concerned over the above-mentioned incidents. No, Popovkin is apparently looking towards the future, as Moscow now believes it is ready to build a manned research base on the moon. "We don’t want the man to just step on the Moon," Popovkin told Vesti FM radio station in an interview transcribed by RIA Novosti. "Today, we know enough about [the moon], we know that there is water in its polar areas." According to Popovkin, Roscosmos is currently "discussing how to begin [the Moon’s] exploration with NASA and the European Space Agency."
Black holes do not exist as we thought they did On January 24, the journal Nature published an article entitled "There are no black holes." It doesn't take much to spark controversy in the world of physics... But what does this really mean? In a brief article published on arXiv, a scientific preprint server, Stephen Hawking proposed a theory of black holes that could reconcile the principles of general relativity and quantum physics. To better understand Hawking's remarks, Forum interviewed Robert Lamontagne, an astrophysicist at the Department of Physics, Université de Montréal, and Executive Director of the Observatoire du Mont-Mégantic. What is a black hole? "According to Einstein's theory of general relativity, a black hole is kind of cosmic central vacuum cleaner that swallows everything in its reach and lets nothing escape. Since it is not visible and has no boundaries as such, a black hole is classically defined by an area of space called the "event horizon," where nothing can escape. In search of the Holy Grail

Phylointelligence: Evolution for Everyone Undetectable Extraterrestrials? World-Leading Physicist Says "They Could Exist in Forms We Can't Conceive" (A Weekend Classic) “I suspect there could be life and intelligence out there in forms we can’t conceive. Just as a chimpanzee can’t understand quantum theory, it could be there as aspects of reality that are beyond the capacity of our brains.” During the conference entitled ‘The Detection of Extra-terrestrial Life and the Consequences for Science and Society’, Rees asked whether the discovery of aliens would cause terror or delight on earth, the Telegraph reported. However, Frank Drake, the founder of SETI and Drake's Equation, told the conference that satellite TV and the “digital revolution” was making humanity invisible to aliens by cutting the transmission of TV and radio signals into space. The earth is currently surrounded by a 50 light year-wide “shell” of radiation from analogue TV, radio and radar transmissions. According to Drake, digital TV signals would look like white noise to a race of observing aliens. For proposition “B” to be correct would defy all logic. Casey Kazan via The Telegraph
