NASA's BARREL Returns From Antarctica
2014-04-25 03:07:10

Karen C. Fox, NASA Three months, 20 balloons, and one very successful campaign: The team for NASA's BARREL – short for Balloon Array for Radiation belt Relativistic Electron Losses -- mission returned from Antarctica in March 2014. In a new NASA Flickr gallery, the team shared their images from weeks of work in the constant sun of the South Pole summer. BARREL's job is to improve our understanding of the mysterious Van Allen belts, two gigantic doughnuts of radiation that surround...

Karen C. Fox, NASA's Goddard Space Flight Center The sun emitted a significant solar flare, peaking at 8:27 p.m. EDT on April 24, 2014. Images of the flare were captured by NASA's Solar Dynamics Observatory. 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 communications signals travel....

Space Weather Tracking From The Ground

April Flowers for redOrbit.com - Your Universe Online How do you measure the effects of space weather on Earth-bound electronics? According to NASA heliophysicist Antti Pulkkinen, with high-voltage power transmission lines and iPads. Pulkkinen, of NASA's Goddard Flight Center, is launching a one-to-two year pilot project this summer by installing scientific substations beneath high-voltage power transmission lines operated by Virginia's Dominion Virginia Power. These substations will...

Saturn's Hexagon: An amazing Phenomenon
2014-04-15 10:10:02

Universidad del País Vasco Researchers of the University of the Basque Country reveal some of the secrets of Saturn's mysterious hexagonal wave, including its rotation period, which could be that of the planet itself In 1980 and 1981 NASA's Voyager 1 and 2 space probes passed for the first time over the planet Saturn, located 1,500 million km from the Sun. Among their numerous discoveries they observed a strange, hexagon-shaped structure in the planet's uppermost clouds surrounding its...

M-class Solar Flare

Karen C. Fox, NASA's Goddard Space Flight Center On April 2, 2014, the sun emitted a mid-level solar flare, peaking at 10:05 a.m. EDT, and NASA's Solar Dynamics Observatory captured imagery of the event. 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 communications signals travel.

redOrbit Staff & Wire Reports - Your Universe Online Using a new method for estimating the moon’s age, an international team of planetary scientists has determined that the satellite formed nearly 100 million years after the formation of the solar system, according to research published Thursday in the journal Nature. The study authors came to that conclusion based on measurements from the Earth’s interior, as well as computer simulations of the protoplanetary disk from which...

Stellar Astrophysics

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...

Image Caption: Artistic concept of a planetary system. Credit: Wikipedia/NASA/JPL-Caltech The term Astronomy encompasses a broad range of topics, including the study of stars, galaxies, and planets. In order to focus on the different areas of study, many subfields of astronomy emerge. One such area is the study of planets known, appropriately, as Planetary Astronomy. Observational Planetary Astronomy Even within the field of Planetary Astronomy, there are several divisions to...

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...

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...
