The heliosphere actually looks like a giant cooked shrimp.
The magnetic field of the sun plays a crucial role in shaping the heliosphere—the domain of the sun—by accelerating the solar wind into a pair of jets College
On Oct. 8, 2013, an explosion on the sun’s surface sent a supersonic blast wave of solar wind out into space. This shockwave tore past Mercury and Venus, blitzing by the moon before streaming toward Earth. The shockwave struck a massive blow to the Earth’s magnetic field, setting off a magnetized sound pulse around the planet.
Two solar PV industry leaders unite under the Coronal-Panasonic Eco Solutions platform GLENDALE, Calif. and CHARLOTTESVILLE, Va., Feb.
NASA’s Solar Dynamics Observatory (SDO) took the 100 millionth image of the sun on Monday, and it's glorious.
Over the next few weeks, NASA will be launching rockets into the famed Northern Lights in Alaska. We've never wanted to watch something more in our lives.
The British Geological Society issued a geomagnetic alert regarding incoming atmospheric disturbances resulting from recent Coronal Mass Ejections from the sun, projected to arrive at Earth on
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 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 GÃ¶sta AlfvÃ©n (May 30, 1908 - April 2, 1995) was a Swedish plasma physicist born in NorrkÃ¶ping, Sweden. AlfvÃ©n 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. AlfvÃ©n made many contributions to plasma physics, including theories describing the...
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...
