Mid-Level Flare Emitted By The Sun
2013-04-11 14:08:16

NASA The M6.5 flare on the morning of April 11, 2013, was also associated with an Earth-directed coronal mass ejection (CME), another solar phenomenon that can send billions of tons of solar particles into space and can reach Earth one to three days later. CMEs can affect electronic systems in satellites and on the ground. Experimental NASA research models show that the CME began at 3:36 a.m. EDT on April 11, leaving the sun at over 600 miles per second. Earth-directed CMEs can cause a...

Powerful Coronal Mass Ejection Erupts On Sun's Earth-Facing Side
2013-03-15 13:42:58

Lawrence LeBlond for redOrbit.com - Your Universe Online A powerful solar eruption occurred on the surface of the sun at 2:54 a.m. (EDT) this morning. The eruption, called a coronal mass ejection (CME), occurred on the Earth-facing side of the sun and may have released billions of tons of solar particles into space racing their way toward Earth, potentially making impact within three days. Once particles from this CME event hit Earth, electrical systems in orbit, in the sky and on...

Sun Erupts With Two CMEs In One Day
2013-03-14 14:15:10

Brett Smith for redOrbit.com - Your Universe Online Earlier this week the sun twice ejected large amounts of solar material during two coronal mass ejections (CMEs) in a 12-hour period, according to a NASA report. The CMEs are not expected to significantly impact Earth. The first CME began at 8:36 p.m. EDT on March 12, 2013. The solar material was directed toward three NASA spacecraft, Spitzer, Kepler and Epoxi. Two of the crafts, Spitzer and Kepler, are in an Earth-like orbit around...

NASA researchers and other scientists will present scientific results and contributions from current and past Mars and moon missions during the 44th Lunar and Planetary Science Conference March 18-22. The conference will take place at the Woodlands Waterway Marriott Hotel and Convention Center at 1601 Lake Robbins Drive in The Woodlands, Texas, near Houston. Presentations will include recent science findings from the rover Curiosity on Mars, and an update on NASA's Gravity Recovery and...

New Satellite Will Provide Earlier Storm Warnings And Space Weather Predictions
2013-03-03 06:04:44

[ Watch the Video: Talking Tornadoes with Tim Samaras ] Alan McStravick for redOrbit.com - Your Universe Online On December 26, 2004, we learned of the importance that early warning systems can play in preventing loss of life when the great Indonesian tsunami caught locals and vacationers alike by surprise. In contrast, on March 11, 2011, the early warning system, while unable to prevent tens of thousands of human casualties, was effectively responsible for preventing a greater loss of...

Van Allen Probes Discover New Radiation Belt, Possibly Due To Solar Storm
2013-02-28 14:59:50

Lee Rannals for redOrbit.com — Your Universe Online NASA announced that its Van Allen Probes have led to a revision of a 50-year-old theory about the Earth's radiation belts. The Van Allen radiation belts surrounding Earth were thought to be just two giant swaths of radiation, first discovered in 1958. More than a half-century later, NASA launched twin probes (August 30, 2012) to create a detailed map of the region and catalogue a variety of energies and particles in these...

Planetary Resources To Join The Hunt For Asteroids

[ Watch the Video: Asteroid 2012 DA14 To Whiz Past Earth Safely ] Lee Rannals for redOrbit.com - Your Universe Online Planetary Resources, a company aimed at mining asteroids, says that its Arkyd-100 Series of spacecraft will be assisting in the detection and characterization of potentially hazardous asteroids near Earth. About 610,000 asteroids are being tracked in the Solar System currently, which is a number that represents less than one percent of the estimated objects that orbit...

UN Prepares For Stormy Space Weather
2013-02-14 11:00:47

NASA Science Rewind to the late 1950s. The Soviet Union had just launched the first artificial satellite, Sputnik. The United States, caught short, was scrambling to catch up, kick-starting a Cold War space race that would last for decades. Space was up for grabs, and it seemed like anything could happen. Into this void stepped the United Nations. In 1958, the General Assembly "recognizing the common interest of mankind in furthering the peaceful use of outer space ... and desiring to...

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 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...
