Supernova Recreation Reveals How Interstellar Magnetic Fields May Have Formed
2014-06-02 10:03:18

Using a laser beam 60,000 billion times more powerful than a typical laser pointer, researchers have recreated a small scale supernova and revealed that cosmic turbulence may have boosted magnetic fields to the power seen in interstellar space.

A coronal mass ejection, or CME, surged off the side of the sun on May 9, 2014, and NASA's newest solar observatory caught it in extraordinary detail.

Saturn's auroras are caused by the same phenomenon which leads to dramatic auroral displays on Earth, University of Leicester research shows.

MMS To Study Secrets Of Magnetic Reconnection
2014-05-16 03:36:18

In March 2015, NASA will launch four identical spacecraft to study how magnetic fields around Earth connect and disconnect, explosively releasing energy – a process known as magnetic reconnection.

Lightning Strikes May Be More Intense Due To Solar Wind Activity
2014-05-16 12:40:11

Previous research has found that the electrical bolts are caused by cosmic radiation and a new study has found that streams of high-energy particles from the Sun accelerated by the solar wind also play a role.

Mars' Atmosphere Loss To Be Measured By NASA's MAVEN Orbiter
2014-05-15 10:47:48

When NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) mission arrives at its destination later this year, an instrument on board could help to determine why Mars has slowly lost much of its atmosphere and become the barren planet we see today.

Cluster Helps To Model The Mysterious Magnetosphere Of Earth
2014-05-09 03:10:38

For many years, scientists have been striving to understand the constantly changing structure and behaviour of the huge magnetic bubble that surrounds our planet. One approach – pioneered by Russian scientist Nikolai Tsyganenko - has been to develop models based on data sent back by spacecraft, such as ESA's Cluster quartet.

Mid-level Solar Flare 050814
2014-05-08 12:01:48

The sun emitted a mid-level solar flare, peaking at 6:07 a.m. EDT on May 8, 2014, and NASA's Solar Dynamics Observatory, or SDO, captured images of it.

Understanding How Sprites Form
2014-05-08 03:55:14

Atmospheric sprites have been known for nearly a century, but their origins were a mystery. Now, a team of researchers has evidence that sprites form at plasma irregularities and may be useful in remote sensing of the lower ionosphere.

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...
