DENVER, Jan. 7, 2013 /PRNewswire/ -- Lockheed Martin (NYSE: LMT) delivered the core structure for the first in a series of the National Oceanic and Atmospheric Administration (NOAA)'s next-generation geostationary weather satellites to the company's Mississippi Space and Technology Center on NASA's Stennis Space Center where it will undergo propulsion system integration. The rigid external structure of the first Geostationary Operational Environmental Satellite-R Series (GOES-R),...

Solar Maximum Is Coming
2012-12-18 19:23:59

Lee Rannals for redOrbit.com — Your Universe Online The sun is revving up and preparing for a new cycle next year, reaching solar maximum during the summer and fall months of 2013. Our star goes through 11-year cycles, roughly. Some cycles can last as long as 14 years or as brief as nine. Despite what the cycle's name suggest, solar storms could be mild during a solar maximum, or severe during a minimum. The sun's cycle is marked from minimum to minimum, making the maximum...

Solar Wind Storms Earth, Enhances Northern Lights
2012-12-17 15:22:33

Lee Rannals for redOrbit.com — Your Universe Online NASA said on Monday that our planet has entered a stream of high-speed solar wind that "escaped" through a coronal hole on the Sun. The solar wind that Earth is passing through has forecasters from the NOAA estimating a slight 20 percent chance of geomagnetic storms, but NASA says that high-latitude residents could benefit from the event. Sky watchers may want to step out into their backyards for the next few nights to...

Combining Planetary Science And Astronomy To Hunt For Exoplanets
2012-11-29 08:41:26

Lawrence LeBlond for redOrbit.com - Your Universe Online Listen to the podcast “How Planets Form” with redOrbit's Dr. John Millis and planet-hunting expert Dr. Eric Mamajek of the University of Rochester. Have you ever looked up at the night sky and wondered just how many of the stars you see might have planets orbiting them, and if so, what those planets might be like? Our galaxy alone contains at least 200 billion stars, and researchers have been searching effortlessly to...

Coronal Mass Ejection Spotted By STEREO
2012-11-21 04:00:32

NASA Image Release: Karen C. Fox, NASA's Goddard Space Flight Center, Greenbelt, Md. On Nov. 20, 2012, at 7:09 a.m. EST, the sun erupted with a 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 can reach Earth one to three days later. When Earth-directed, CMEs can affect electronic systems in satellites and on Earth. Experimental NASA research models, based on observations from the Solar...

Space Weather Week Highlights ESA's Situation Awareness Program
2012-11-09 19:16:44

Lee Rannals for redOrbit.com — Your Universe Online The European Space Agency's (ESA) Space Situational Awareness program was spotlighted this week during the ninth European Space Weather Week. The Space Situational Awareness (SSA) program's recent developments in space weather activities were showcased during the conference. As part of SSA, ESA's space weather specialists are focused on developing warning services to help protect satellites and ground infrastructure. These...

Vesta May Hold The Secret To Youth
2012-10-31 13:50:22

Lee Rannals for redOrbit.com - Your Universe Online NASA's Dawn spacecraft has revealed data that shows protoplanet Vesta is continually stirring its outermost layer. The data shows that a common form of weathering that affects many airless bodies like Vesta in the inner solar system helps to keep them looking younger by not aging the outermost layer. Findings described in an upcoming issue of the journal Nature show that data indicates that carbon-rich asteroids have been...

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...

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...
