WASHINGTON, Aug. 29, 2014 /PRNewswire-USNewswire/ -- NASA's twin Van Allen Probes will celebrate on Saturday two years of studying the sun's influence on our planet and near-Earth space. The probes, shortly after launch in August 2012, discovered a third radiation belt around Earth when only two had previously been detected. http://photos.prnewswire.com/prnvar/20081007/38461LOGO The radiation belts are layers of energetic charged particles held in place by the magnetic field surrounding...

Karen C. Fox, NASA's Goddard Space Flight Center On Aug. 24, 2014, the sun emitted a mid-level solar flare, peaking at 8:16 a.m. EDT. NASA's Solar Dynamics Observatory captured images of the flare, which erupted on the left side of the sun. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and...

aurora dances in the atmosphere
2014-08-21 10:07:12

Karen C. Fox, NASA's Goddard Space Flight Center On the evening of Aug. 20, 2014, the International Space Station was flying past North America when it flew over the dazzling, green blue lights of an aurora. On board, astronaut Reid Wiseman captured this image of the aurora, seen from above. This auroral display was due to a giant cloud of gas from the sun – a coronal mass ejection or CME – that collided with Earth's magnetic fields on Aug. 19, 2014, at 1:57 a.m. EDT. This event set...

April Flowers for redOrbit.com - Your Universe Online University of Bristol’s professor of Aerospace Engineering Ashley Dale cautions that “solar super-storms” are going to cause “catastrophic” and “long-lasting” impacts if we continue to ignore the threat of such storms. Dale is a member of the international task force SolarMAX, which was designed to identify the risks of a solar storm and how humanity could minimize the risks. He believes that a particularly violent...

Stuart Wolpert, University of California - Los Angeles Earth and Mercury are both rocky planets with iron cores, but Mercury's interior differs from Earth's in a way that explains why the planet has such a bizarre magnetic field, UCLA planetary physicists and colleagues report. Measurements from NASA's Messenger spacecraft have revealed that Mercury's magnetic field is approximately three times stronger at its northern hemisphere than its southern one. In the current research,...

Dr. Tony Phillips, Science@NASA If an asteroid big enough to knock modern civilization back to the 18th century appeared out of deep space and buzzed the Earth-Moon system, the near-miss would be instant worldwide headline news. Two years ago, Earth experienced a close shave just as perilous, but most newspapers didn't mention it. The "impactor" was an extreme solar storm, the most powerful in as much as 150+ years.

Brett Smith for redOrbit.com - Your Universe Online An investigation of Vesta, a massive asteroid that orbits the Sun between Mars and Jupiter, has revealed that the planet-like body has a thicker crust than previously thought, which calls into question the internal structures of other planets in the Solar System. The investigation, which is published in the journal Nature, is based on data from the Dawn spacecraft that NASA sent into Vesta's orbit between July 2011 and July 2012. Using...

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...

Ring Current

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...

Planetary Ring -- A planetary ring is a ring of dust and other small particles orbiting around a planet in a flat disc-shaped region. The most spectacular and famous planetary rings are those around Saturn, but all four of the solar system's gas giant planets (Jupiter, Saturn, Uranus, Neptune) possess ring systems of their own. The origin of planetary rings is not precisely known, but they are thought to be unstable and dissipate over the course of tens or hundreds of millions of...
