Several Key Discoveries During Van Allen Probes’ First Year
2013-09-01 07:49:38

redOrbit Staff & Wire Reports – Your Universe Online NASA’s twin Van Allen Probes entered their second year of service Friday having already provided a wealth of new information about the layers of energetic charged particles located above our planet. According to the US space agency, data collected by the probes since their August 30, 2012 launch has already led to “several significant discoveries” about the Van Allen radiation belts -- some of which came within the first...

Scientists Observe Magnetic Flow On The Sun
2013-08-28 19:43:38

Lee Rannals for redOrbit.com – Your Universe Online NASA's Solar Dynamics Observatory has helped scientists figure out a little more about what is going on inside the sun. The SDO has an instrument onboard known as the Helioseismic and Magnetic Imager (HMI). This instrument has allowed scientists to observe a two-level system of circulation within the sun. Understanding this circulation will be especially important in the coming months as the sun's magnetic poles flip. The sun is...

Twin Star Insights Into Sun's Future
2013-08-28 13:47:51

[ Watch the Video: The Life Cycle of a Sun-Like Star ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers have identified what they are calling the Sun's oldest twin, HIP 102152, sitting 250 light-years away from us. A team of astronomers using the European Southern Observatory's (ESO) Very Large Telescope (VLT) found that HIP 102152 is older but otherwise nearly identical to our Sun, giving astronomers a chance to see how our local star will look as it ages. Our Sun is...

Another Earth-Directed Coronal Mass Ejection
2013-08-22 06:59:09

NASA On August 21, 2013 at 1:24 am EDT, the sun erupted with an Earth-directed coronal mass ejection, or CME, a solar phenomenon that can send billions of tons of particles into space and reach Earth one to three days later. These particles cannot travel through the atmosphere to harm humans on Earth, but they can affect electronic systems in satellites and on the ground. Experimental NASA research models, based on observations from NASA’s Solar Terrestrial Relations Observatory show...

Auroras Recreated In The Lab
2013-08-22 05:08:58

April Flowers for redOrbit.com - Your Universe Online One of the most beautiful sights in North America is the Aurora Borealis, the famous Northern Lights. A team of scientists have discovered the tools necessary to recreate the colorful light show, and have brought the Northern Lights to a lab at NASA’s Langley Research Center. A device called the Planeterrella combines all the necessary ingredients - a magnetic field, charged particles, and a sphere – to create the simulation of...

Air Force Scientists Share Insights About Lab-Created Ball Lightning
2013-08-20 13:15:52

Lee Rannals for redOrbit.com - Your Universe Online Ball lightning is a phenomenon that has puzzled some of the best minds for generations, including Aristotle and Nikola Tesla. Now, scientists from the US Air Force Academy say they have some new insights into reproducing the rare form of lightning in the laboratory. The phenomenon consists of a floating, glowing ball that drifts eerily through the sky and then explodes violently. It sometimes can injure people and damage buildings....

NASA’s dramatic video of a black-topped sun on the verge of flipping its magnetic polarity has captivated people. Friends of Science say the current low solar sunspot activity, not seen in 200 years, is a pattern that historically preceded global cooling and that the sun is the main driver of climate change, not carbon dioxide. Calgary, Alberta, Canada (PRWEB) August 15, 2013 Climate change on earth is significantly affected by the changing 11 year solar magnetic cycles, according to...

Has Voyager 1 Finally Left The Solar System? New Analysis Reveals Compelling Evidence
2013-08-15 13:47:59

Brett Smith for redOrbit.com - Your Universe Online According to a new analysis from scientists at the University of Maryland, NASA's Voyager 1 has finally left the Solar System – marking the first time a man-made object has entered the Milky Way outside of the Sun’s influence. "It's a somewhat controversial view, but we think Voyager has finally left the Solar System, and is truly beginning its travels through the Milky Way," said study author Marc Swisdak, a UMD plasma physicist....

Stunning Solar Images From Big Bear
2013-08-07 08:51:48

April Flowers for redOrbit.com - Your Universe Online New and remarkably detailed photos of the Sun have been obtained by researchers at the New Jersey Institute of Technology's (NJIT) Big Bear Solar Observatory (BBSO) in Big Bear, California, with the New Solar Telescope (NST). Never-before-seen details of solar magnetism revealed in photospheric and chromospheric features are observed in these new photographs. "With our new generation visible imaging spectrometer (VIS), the solar...

How Solar Cycles Impact Our Weather Here On Earth
2013-01-13 09:10:34

Solar cycles: what are they and why should we care about them? Solar cycles are made up of what are known as solar minimums (min) and solar maximums (max). We refer to a solar min at the time when the sun is not active with many sunspots, while a solar max is just the opposite when we see a large increase in sunspot activity. So how long do solar cycles last? Typically they run on what is known as an 11 year cycle from the max to the min and then start over again anew. As of 2012 we...

Solar Physics
2012-05-02 19:16:53

Solar Physics is a journal for solar and solar-stellar research and the study of solar terrestrial physics. Founded in 1967 by solar physicist Cornelis de Jager and publisher D. Reidel, the journal treats all aspects of solar physics, ranging from the internal structure of the Sun and its evolution, to outer corona and solar wind in interplanetary space. Solar Physics has four more than forty years been the principal journal for publications of fundamental research on the Sun. It is...

A Radio Atmospheric signal (sometimes referred to as Sferic or Spheric), is a broadband electromagnetic impulse that occurs during atmospheric lightning discharges. Sferics spread out from the lightning source and can be received thousands of miles away. A sferic, depending on atmospheric conditions, may extend anywhere from a few kHz to several tens of kHz. Sferics from far reaching storms, over 1500 miles away, are generally offset in frequency range and may be picked up as tweeks. A...

Hannes Olof Gösta Alfvén (May 30, 1908 - April 2, 1995) was a Swedish plasma physicist born in Norrköping, Sweden. Alfvén received his PhD from the University of Uppsala in 1934. His thesis was titled "Investigations of the Ultra-short Electromagnetic Waves." He was originally trained as an electrical power engineer and later moved on to research and teaching in the fields of plasma physics. Alfvén made many contributions to plasma physics, including theories describing the...

Ring Current
2004-10-19 04:45:44

Ring Current -- A ring current is an electric current carried by charged particles trapped in a planet's magnetosphere. It is caused by the longitudinal drift of energetic (10-200 keV) particles. Earth's Ring Current Earth's ring current is responsible for geomagnetic storms. The ring current system consists of a band, at a distance of 3-5 RE(1), which lies in the equatorial plane and circulates clockwise around the Earth (when viewed from the north). The particles of this region...
