Cosmic Turbulence Black Hole Formation
2013-08-16 09:31:01

John P. Millis, PhD for redOrbit.com - Your Universe Online The mechanism by which stars and black holes are formed in extreme cases of high mass density has puzzled astronomers since Johannes Kepler first laid out his laws of planetary motion some 400 years ago. In the most basic sense, a large cloud of gas condenses into a rotating disk. Mass is then directed towards the center of the cloud where, due to the increasing density, a stellar body is eventually formed. One challenge to...

Odd Magnetar Has A Very Strong Magnetic Field
2013-08-15 04:36:30

redOrbit Staff & Wire Reports - Your Universe Online An odd type of neutron star located approximately 6,500 light years from Earth has one of the strongest magnetic fields in the universe – despite previous suggestions it possessed an unusually low magnetic field. Using the European Space Agency’s (ESA) XMM-Newton space telescope, a team of astronomers studied the object, a magnetar known as SGR 0418+5729 (SGR 0418). This dense and compact object, which is the dead core of a...

Theoretical Possibility Of Large, Hollow Magnetic Cage Molecules Discovered By VCU Physicists
2013-07-31 13:32:46

Virginia Commonwealth University New molecules could be larger than the original Buckminster fullerene with potential applications in technology and health care Virginia Commonwealth University researchers have discovered, in theory, the possibility of creating large, hollow magnetic cage molecules that could one day be used in medicine as a drug delivery system to non-invasively treat tumors, and in other emerging technologies. Approximately 25 years ago, scientists first made the...

Magnetic Pen For Smartphones: KAIST
2013-07-25 04:31:57

[ Watch the Video: MagPen Enhances Pen Interaction On Smartphones ] Lee Rannals for redOrbit.com - Your Universe Online Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have developed a new pen to extend existing features on smartphones. The MagPen is a magnetically driven pen interface that works both on and around tablets and smartphones that have magnetometers embedded in them. The team came up with a technology that enabled an input tool for mobile...

Magnetic Waves Responsible For Keeping Sun's Corona Heated
2013-07-09 15:10:08

Lee Rannals for redOrbit.com - Your Universe Online Astronomers at the 44th meeting of the Solar Physics Division (SPD) of the American Astronomical Society are shedding light on the Sun's coronal heating mystery. The team found evidence magnetic waves in a polar coronal hole contain enough energy to heat the corona and deposit most of their energy at sufficiently low heights for the heat to spread throughout the corona. Their observations help answer a 60-year-old solar physics mystery...

Curious Flips Observed In Tau Boo's Magnetic Cycle
2013-07-04 03:58:06

Lee Rannals for redOrbit.com - Your Universe Online One star sitting 51 light years away in the constellation of Bootes has a magnetic cycle that is puzzling astronomers. Dr Rim Fares presented the first observations of the complete magnetic cycle of Tau Bootis, or Tau Boo, at the Royal Astronomical Society's National Astronomy Meeting in St Andrews this week. These are the first observations of the complete magnetic cycle of a star other than our Sun. According to the findings, in...

Scientists Study Coronal Loops To Gain Insight Into Solar Dynamics
2013-07-02 18:21:44

John P. Mills, Ph.D. for redOrbit.com -- Your Universe Online Solar flares and the even more violent Coronal Mass Ejections (CMEs) are spectacular events, driving enormous amounts of energy and streams of charged particles into space. While researchers have had the opportunity to study these events for decades, we are still learning about what initiates these explosions. Previous studies have revealed that twisted magnetic field lines within the solar structure will pierce the surface...

The new Model 121 current source provides a reliable and affordable alternative to more expensive multi-function current sources. Columbus, OH (PRWEB) June 05, 2013 Lake Shore announced today the introduction of its Model 121 programmable DC current source to its family of products to support precision test and measurement. The Model 121 will replace the existing Model 100, 101, 102, 110 and 120 current sources, offering a singular, easy-to-use instrument with expanded capabilities and...

NASA X-Ray Observatory Reveals Magnetars More Common Than Thought
2013-05-24 14:42:15

Lee Rannals for redOrbit.com — Your Universe Online NASA's Chandra X-ray Observatory has revealed that some of the most extreme objects in the universe may be more common than previously thought. Magnetars are the dense remains of dead stars that erupt sporadically with bursts of high-energy radiation. When a massive star runs out of fuel its core collapses to form a neutron star. Most neutron stars spin rapidly, but a small fraction have a relatively low spin rate while also...

Magnetic Field Model Of Sun Explains Solar Activity Cycles
2013-05-23 08:32:58

April Flowers for redOrbit.com - Your Universe Online Since the 18th Century, scientists have been aware that the Sun oscillates between periods of high and low solar activity in an 11-year cycle. So far, though, they have been unable to fully explain how this cycle is generated. Understanding the Sun´s magnetic activity has become increasingly important as we rely more on our electronic devices. Changes in the magnetic field are responsible for “space weather”...
