Latest Geomagnetism Stories

41,000 years ago, a complete and rapid reversal of the geomagnetic field occured. Magnetic studies of the GFZ German Research Centre for Geosciences on sediment cores from the Black Sea show that during this period, during the last ice age, a compass at the Black Sea would have pointed to the south instead of north. Moreover, data obtained by the research team formed around GFZ researchers Dr. Norbert Nowaczyk and Prof. Helge Arz, together with additional data from other studies in the North...

[Watch The Video] [Listen to EarthSong] Lawrence LeBlond for redOrbit.com - Your Universe Online Earth is filled with many sounds and no matter where you go it is inescapable. From the roar of the city streets, to the ever-pleasing sounds of nature, and the endless commotion of human chatter. But there is one sound that most of us have never heard: the sound of the Earth itself. The sound (or song) is called “chorus,” explains Craig Kletzing of the University of Iowa. This...

[ Watch the Video: STEREO Captures Fastest CME to Date ] Lee Rannals for redOrbit.com - Your Universe Online NASA's STEREO spacecraft has observed the fastest coronal mass ejection (CME) ever seen on the Sun. The Solar TErrestrial RElations Observatory (STEREO) clocked the massive eruption traveling between 1,800 and 2,000 miles per second as it ejected from the sun. NASA said this was the fastest CME ever observed by STEREO, which launched back in 2006. "Between 1,800 and...

On a time scale of tens to hundreds of millions of years, the geomagnetic field may be influenced by currents in the mantle. The frequent polarity reversals of Earth's magnetic field can also be connected with processes in the mantle. These are the research results presented by a group of geoscientists in the new advance edition of "Nature Geoscience" on Sunday, July 29th. The results show how the rapid processes in the outer core, which flows at rates of up to about one millimeter per...

SAN DIEGO, May 29, 2012 /PRNewswire/ -- Mountain systems characterized by folding, such as the Teton Range of the Rocky Mountains, have been intensively studied and debated since the 19th Century. The age-old problem of fold-mountain formation reduces to this question: How can one account for the "extra" surface area, contained within the continental boundaries, that observations reveal folded atop other layers? For decades, in the plate tectonic view, mountain-building has been...

[ Watch the Video ] Last month, when the sun unleashed the most intense radiation storm since 2003, peppering satellites with charged particles and igniting strong auroras around both poles, a group of high school students in Bishop, California, knew just what to do. They launched a rubber chicken. The students inflated a helium balloon and used it to send the fowl, named "Camilla," to an altitude of 120,000 ft where she was exposed to high-energy solar protons at point blank range....

Massive solar flares could bring down the national electrical grid and affect power in the U.S. “for a period of years,” according to a 2009 NASA report. On March 27th Jack Jobe, Emmy-nominated journalist and survival teacher, shows how to prepare yourself and your family on National Geographic’s “Doomsday Preppers.” Aurora, Colorado (PRWEB) March 24, 2012 National Geographic takes viewers inside the world of Jack Jobe, a “Common Sense Survival Teacher.” Jack, founder of...

TRUCKEE, Calif., Jan. 30, 2012 /PRNewswire/ -- Solar flares are all over the news as we head towards the next "solar maximum" in 2012/2013. With recent brilliant displays of northern lights, scientists are concerned that this next solar maximum could deal a devastating blow to our electronic power grid and communications systems. Periods of intense solar activity occur once every eleven years when our sun's magnetic poles flip and the sun sends powerful waves of charged particles...

Improved Forecasting to Coincide with Peak in Solar Activity After years of relative somnolence, the sun is beginning to stir. By the time it's fully awake in about 20 months, the team at NASA’s Goddard Space Flight Center in Greenbelt, Md., charged with researching and tracking solar activity, will have at their dispoal a greatly enhanced forecasting capability. Goddard's Space Weather Laboratory recently received support under NASA's Space Technology Program Game Changing Program to...

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...
