Sun Emits Another X-Class Solar Flare
2013-11-19 11:53:37

NASA Adding on to a series of solar flares throughout October and November, the sun emitted another significant solar flare on Nov. 19, 2013, peaking at 5:26 a.m. EST. 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. To see how this event may impact Earth,...

WASHINGTON, Nov. 5, 2013 /PRNewswire-USNewswire/ -- NASA has selected nine research teams from seven states for a new institute that will bring researchers together in a collaborative virtual setting to focus on questions concerning space science and human space exploration. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The teams participating in the Solar System Exploration Research Virtual Institute (SSERVI) will address scientific questions about the moon, near-Earth...

Sun Produces Fourth X-class Flare In A Week
2013-10-30 11:04:01

NASA The sun emitted a significant solar flare – its fourth X-class flare since Oct. 23, 2013 -- peaking at 5:54 p.m. on Oct. 29, 2013. 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. This disrupts the radio signals for as long as the flare is ongoing,...

Recalling The 2003 Nightmare Halloween Magnetic Storm

[ Watch the Video: Is There Space Weather In Store For Trick-Or-Treaters? ] Lawrence LeBlond for redOrbit.com - Your Universe Online As Halloween approaches, most people are thinking about costume parties, tricks and treats, haunted hayrides and perhaps a rogue werewolf running amok. But for scientists, this October 31 may provide a scare much different from what most kids get when they go Trick-or-Treating this All Hallow's Eve. The NOAA/NWS Space Weather Prediction Center on...

Sun Continues To Produce Solar Flares
2013-10-28 11:08:45

NASA After emitting its first significant solar flares since June 2013 earlier in the week, the sun continued to produce mid-level and significant solar flares on Oct. 27 and Oct. 28, 2013. 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. To see how...

Is The Solar Maximum Peak Upon Us? Increase In Sun's Activity May Tell
2013-10-26 08:22:09

[ Watch the Video: Our Sun Is Flaring Up ] Lawrence LeBlond for redOrbit.com - Your Universe Online Our sun, the bright yellow disk that sits at the center of the Solar System providing us with light, energy and warmth, has a much darker side that also has the potential to disrupt, rather than preserve, life on Earth. Experts know that the sun goes through a natural solar cycle about every 11 years, marked by an increase and decrease of sunspots – visible blemishes that appear on...

Third Solar Flare Emitted By The Sun In Two Days
2013-10-25 12:12:19

NASA [ Watch The Video: Experimental NASA Research Model of Path for Oct. 22-23 CMEs ] The M9.4 flare on Oct. 23, 2013, was associated with a coronal mass ejection or CME, a solar phenomenon that can send billions of tons of particles into space that can reach Earth one to three days later. These particles cannot travel through the atmosphere to harm humans on Earth, but they can affect electronic systems in satellites and on the ground. Another solar flare erupted from the same area...

NASA's SDO Captures Image Of Mid-level Solar Flare
2013-10-24 12:46:59

NASA The sun emitted a mid-level solar flare that peaked at 8:30 pm EDT on Oct. 23, 2013. 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. Such radiation can disrupt radio signals for as long as the flare is ongoing, anywhere from minutes to hours. To see...

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...
