Solar Flare Collides With Earth Causing Disruptions
2012-01-25 10:51:51

[ Watch the Video ] A solar flare from Sunday collided with Earth on Tuesday, becoming the largest solar radiation storm since October 2003. NOAA's Space Weather Prediction Center has categorized the storm as "strong," or an S3, storm.  These storms can affect satellite operations and short wave radio propagation, but do not cause any harm to humans on Earth. Some polar flights, including a dozen Delta Air Lines planes, were re-routed to avoid communications lapses and exposing...

Worst Solar Storm Since 2005 To Hit Earth Tuesday
2012-01-23 16:15:09

The National Oceanic and Atmospheric Agency's (NOAA) Space Weather Prediction Center (SWPC) issued a geomagnetic storm watch as experts predicted that the biggest solar storm since 2005 is expected to hit Earth Tuesday morning, various media outlets are reporting. According to Fox News reports, at approximately 11pm Eastern time on Sunday night, the sun released an "immense blast of plasma" that has caused authorities to redirect the flight plans of certain high-altitude aircraft. In...

December 25 Solar Storm Could Knock Out Radio Signals
2011-12-29 04:49:43

Scientists have warned of a major solar storm hitting the Earth that could possibly knock out radio signals. Experts expect radio blackouts for a few days after the radiation from the coronal mass ejection (CME) hits our planet. The flare is part of a larger increase in activity in the Sun, which is expected to peak around 2013. "Category G1 (Minor) geomagnetic storms are expected 28 and 29 December due to multiple coronal mass ejection arrivals," the National Oceanic and Atmospheric...

Solar System Ejected A Giant Planet 600 Million Years Ago
2011-11-11 06:10:42

According to a study published in The Astrophysical Journal Letters, our solar system may have ejected a giant planet from its orbit and spared the Earth. Experts wrote that Jupiter had helped eject another giant planet from our solar system when it was about 600 million years old. "We have all sorts of clues about the early evolution of the solar system," author Dr. David Nesvorny of the Southwest Research Institute said in a press release. "They come from the analysis of the...

SDO Spots Largest Sunspots In Years
2011-11-04 11:20:44

NASA's Solar Dynamics Observatory (SDO) spotted one of the largest new sunspots to have appeared on the surface of the sun in years. The area is nearly 25,000 miles wide, which is over three times larger than the Earth. NASA said the region has already experienced about eight solar flares, including an M-class flare on November 2. The space agency also said that X-class flares are possible, which includes the largest possible solar flares. The sun shot off a flare from this region...

Image 1 - Space Weather Prediction Model Improves NOAA’s Forecast Skill
2011-10-21 03:07:21

[ Watch the Video ] NOAA is now using a sophisticated forecast model that substantially improves predictions of space weather impacts on Earth. Better forecasts offer additional protection for people and the technology-based infrastructure we use daily. Explosions in the sun´s outer atmosphere — tracked and forecast by NOAA scientists — can cause geomagnetic and solar radiation storms at Earth that can impede the operation of electrical power grids, interfere with the...

NASA's Dawn Science Team Presents Early Science Results
2011-10-13 10:19:27

Scientists with NASA's Dawn mission are sharing with other scientists and the public their early information about the southern hemisphere of the giant asteroid Vesta. The findings were presented today at the annual meeting of the Geological Society of America in Minneapolis, Minn. Dawn, which has been orbiting Vesta since mid-July, has found that the asteroid's southern hemisphere boasts one of the largest mountains in the solar system. Other findings show that Vesta's surface, viewed by...

NASA To Perform Student Experiments On International Space Station
2011-10-08 05:17:16

NASA announced it will provide support to Space Adventures, Ltd. of Vienna, Va., to conduct a global competition for students to design experiments that will be performed in space and broadcast around the world. NASA entered into a non-reimbursable Space Act Agreement with Space Adventures for astronauts aboard the International Space Station 250 miles above Earth to conduct the winning experiments on the orbiting outpost. The experiments will be performed on the U.S. portion of the space...

MESSENGER scientists will highlight the latest results on Mercury from MESSENGER observations obtained during the first six months (the first Mercury solar day) in orbit. These findings will be presented October 5 in 30 papers and posters as part of a special session of the joint meeting of the European Planetary Science Congress and the Division for Planetary Sciences of the American Astronomical Society in Nantes, Frances. Scientists will also look ahead to MESSENGER observations still...

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...

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...
