The world was on edge earlier this month when North Korea detonated an underground nuclear explosion meant to showcase to the world community the abilities of this beleaguered nation.

Flare, Ejection And Rain All Caught In Spectacular Solar Show
2013-02-20 15:40:05

An eruption on the sun can be a beautiful, monstrous event, and NASA's Solar Dynamics Observatory has helped to bring these dangerous coronal mass ejections right to our computer screens.

Fast-Growing Sunspot Observed By NASA's SDO
2013-02-20 14:28:12

As magnetic fields on the sun rearrange and realign, dark spots known as sunspots can appear on its surface. Over the course of Feb. 19-20, 2013, scientists watched a giant sunspot form in under 48 hours.

Cassini Catches Solar Wind, Helps NASA Study Particle Acceleration
2013-02-20 14:23:12

As it floats around the planet Saturn, the Cassini spacecraft recently got a front row seat to what NASA astronomers are calling an “unusual strong blast of solar wind.” Shortly after this “wind” blew by, Cassini began detecting particles which had been accelerated to ultra-high energies.

Alpha Centauri B May Shed Light On Our Own Sun’s Anomalies
2013-02-20 12:52:10

ESA scientists have recently discovered that neighbor star Alpha Centauri A displays some of the same bizarre temperature phenomena as our Sun and may help to solve a long-standing solar mystery.

Understanding The Magnetosphere Better Than Ever With Help From THEMIS
2013-02-20 10:47:18

On Earth, scientists can observe weather patterns, and more importantly can predict them, through the use of tens of thousands of weather observatories scattered around the globe.

Highlights For NASA's Solar Dynamics Observatory Third Year
2013-02-11 14:54:31

On Feb. 11, 2010, NASA launched an unprecedented solar observatory into space.

Earth-Directed CME Released Associated With A Long Duration Solar Flare
2013-02-11 08:01:42

On Feb. 9, 2013 at 2:30 a.m. EST, the sun erupted with an Earth-directed coronal mass ejection or CME, associated with a long duration C2.4-class flare.

NASA Constructs Lobster Eye Imager
2013-02-08 10:59:10

To study a poorly understood phenomenon known as charge exchange, NASA scientists teamed up to build NASA's first wide-field-of-view soft X-ray camera using "lobster eye" technology.

Experts Say Solar Superstorm May Be Imminent: Readiness Is Key
2013-02-08 09:29:17

A solar superstorm may be brewing and there is little we can do to prevent it from disrupting our communications and electrical systems here on Earth.

The prominent feature that allows for the existence of life on Earth is the Sun. Radiation from our closest star provides heat and energy to our planet, driving biological processes and providing the necessary conditions for liquid water to naturally exist. But our Sun is only but one star in this vast Universe. And as it turns out, most stars are quite different than the one that illuminates our day. For this reason, scientists have, for hundreds of years, attempted to study the other...

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...

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...

postliminy
  • In Roman antiquity, the return of a person who had been banished, or taken prisoner by an enemy, to his old condition and former privileges.
  • In international law, that right by virtue of which persons and things taken by an enemy in war are restored to their former status when coming again under the power of the nation to which they belonged.
The word 'postliminy' comes from a Latin word meaning 'threshold'.
