No Planetary Influence On Solar Activity
2013-09-05 14:37:53

Lee Rannals for redOrbit.com - Your Universe Online New research in Astronomy & Astrophysics (A&A) is correcting errors in one statistical study published in the same journal last yea,r regarding the isotopic records of solar activity. Last year, astronomers wrote in the journal claiming that there is evidence of planetary influence on solar activity. However, the latest study refutes that claim, saying that they found no evidence of any planetary effect on the Sun. The Sun...

NASA's Goddard Space Flight Center Visitor Center in Greenbelt, Md. will host this month's Sunday Experiment on Sunday, Sept. 15 from 1 to 3 p.m. EDT. The Sunday Experiment is a free afternoon for children of all ages and their families to discover NASA Goddard's exciting missions. The Sept. 15 Sunday Experiment will explore NASA's Solar Dynamics Observatory (SDO) mission. SDO was launched in 2010, and is currently studying solar activity and how it causes space weather. Space weather...

Another Earth-Directed Coronal Mass Ejection
2013-08-22 06:59:09

NASA On August 21, 2013 at 1:24 am EDT, the sun erupted with an Earth-directed coronal mass ejection, or CME, a solar phenomenon that can send billions of tons of particles into space and 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. Experimental NASA research models, based on observations from NASA’s Solar Terrestrial Relations Observatory show...

Solar Flip Soon
2013-08-06 13:41:02

Brett Smith for redOrbit.com - Your Universe Online [ Watch the Video: Preparing For The Solar Max Magnetic Flip ] Solar experts are anticipating a major event that is about to happen within the next three or four months - the sun is going to flip. Every eleven years, the Sun reaches the peak of its cycle and proceeds to switch polarity, making north become south and south become north. NASA scientists said the upcoming change will also mark the halfway point of solar max, a period...

GOES-R Satellite Magnetometer Boom Deployment Test Successful
2013-07-30 10:33:57

NASA [ Watch the Video GOES-R Magnetometer Boom Deployment] The GOES-R Magnetometer Engineering Development Unit made an important development in the construction of the spacecraft recently after completing a successful boom deployment test at an ATK facility in Goleta, Calif. The Geostationary Operational Environmental Satellite -- R Series advanced spacecraft and instrument technology will result in more timely and accurate weather forecasts. It will improve support for the...

Coronal Mass Ejection Witnessed By NASA's STEREO
2013-07-23 08:59:36

NASA On July 22, 2013, at 2:24 a.m. EDT, the sun erupted with a coronal mass ejection or CME, a solar phenomenon that can send billions of tons of solar particles into space that can affect electronic systems in satellites. Experimental NASA research models based on observations from NASA's Solar Terrestrial Relations Observatory, or STEREO, show that the CME was not Earth-directed, but may pass Mars.  It left the sun at around 715 miles per second, which is a fairly fast speed...

SOHO Video Shows Eruptions On Sun
2013-07-22 18:13:12

Lee Rannals for redOrbit.com - Your Universe Online A new video posted by the European Space Agency (ESA) shows two solar eruptions taking place side-by-side. The video, taken by ESA and NASA's Solar and Heliospheric Observatory (SOHO) on July 1 through 2 this year, shows two coronal mass ejections (CMEs) launching plasma into interplanetary space. CMEs are huge clouds of magnetized plasma ejecting from the Sun's atmosphere, which is known as the corona. These ejections comprise...
