NASA's Marshall Space Flight Center will host a national workshop for the Study on Applications for Large Space Optics (SALSO) Feb. 5-6. The workshop will feature presentations on concepts for the use of two large space telescopes that were transferred to NASA last year. The SALSO workshop will help develop concepts aligned with five principal areas: space technology focused research, validation or demonstration; human exploration and operations; heliophysics; planetary science; and...

Venus Caught Looking Like A Comet
2013-01-30 04:35:17

[ Watch the Video: What is Venus? ] John P. Millis, Ph.D. for redOrbit.com — Your Universe Online At the very edges of the Earth´s atmosphere, where the Earth´s magnetic field begins, solar radiation strips electrons from the tenuous gas that is slowly leaking into space. This region, known as the ionosphere is famously responsible for allowing terrestrial radio transmissions over great distances. During World War II, for example, radio operators would...

Sun Unleashes Two Coronal Mass Ejections On January 23
2013-01-25 05:43:18

[ Watch the Video: SOHO Captures CME On January 23, 2013 ] Lee Rannals for redOrbit.com - Your Universe Online The sun showed off its strength on Wednesday with two coronal mass ejections (CME), observed by both NASA and the European Space Agency instruments. NASA's Solar Terrestrial Relations Observatory (STEREO) and both of the space agencies' Solar and Heliospheric Observatory (SOHO) helped to unveil the activity during the solar maximum cycle. The CME seen at 9:55 a.m. EST on...

Asteroid Mining Company Builds 24-Pound Telescope For Future Space Missions
2013-01-22 06:59:54

[Watch Video: Planetary Resources Tech Update] Lawrence LeBlond for redOrbit.com - Your Universe Online An asteroid mining company this week has unveiled a space telescope it plans to implement in upcoming deep space missions. The telescope, a prototype of its Arkyd-100, is tentatively planned for a 2014 launch with the hopes of aiding in the harvest of precious metals and water from near-Earth asteroids (NEAs) by 2020. Planetary Resources is the company behind this lucrative...

Auroras Exist Elsewhere Besides Earth, Say Planetary Scientists
2013-01-21 15:01:22

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online Every year, eager sky watchers travel to the northern reaches of the Earth to catch a glimpse of the northern lights. This spectacle of color in the atmosphere — the Aurora Borealis and its companion to the south, the Aurora Australis — arises as the solar wind interacts with our atmosphere. When charged particles from our Sun hit our atmosphere, oxygen and nitrogen atoms become excited. As the atoms relax,...

New Sunspots Producing Space Weather
2013-01-15 05:07:09

Karen C. Fox, NASA's Goddard Space Flight Center, Greenbelt, Md. On Jan. 13, 2013, at 2:24 a.m. EST, the sun erupted with an Earth-directed coronal mass ejection or CME. Not to be confused with a solar flare, a CME is a solar phenomenon that can send solar particles into space and reach Earth one to three days later. Experimental NASA research models, based on observations from the Solar Terrestrial Relations Observatory (STEREO) and the ESA/NASA mission the Solar and Heliospheric...

Stellar Astrophysics
2014-01-12 00:00:00

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...

Planetary and Space Science
2012-05-28 10:21:45

Planetary and Space Science is a peer-reviewed scientific journal established in 1959 and published by Elsevier 15 times per year. As of May 2012, the editor-in-chief is Rita Schulz (The Netherlands). The journal publishes original research articles and short communications. The main focus is on solar system processes which encompass multiple areas of the natural sciences. Research that involves planetary and space sciences involves many disciplines. Celestial mechanics is part of these...

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...
