Latest Coronal mass ejection Stories

NASA [ Watch The Video ] On Jan. 31, 2013 at 2:09am EST, the sun erupted with an Earth-directed coronal mass ejection or CME. Experimental NASA research models, based on observations from the Solar Terrestrial Relations Observatory (STEREO) and ESA/NASA’s Solar and Heliospheric Observatory, show that the CME left the sun at speeds of around 575 miles per second, which is a fairly typical speed for CMEs. Historically, CMEs at this speed are mild. Not to be confused with a solar...

[ Watch the Video: SOHO Captures CME On January 23, 2013 ] Lee Rannals for redOrbit.com - Your Universe Online The sun showed off its strength on Wednesday with two coronal mass ejections (CME), observed by both NASA and the European Space Agency instruments. NASA's Solar Terrestrial Relations Observatory (STEREO) and both of the space agencies' Solar and Heliospheric Observatory (SOHO) helped to unveil the activity during the solar maximum cycle. The CME seen at 9:55 a.m. EST on...

Karen C. Fox, NASA's Goddard Space Flight Center, Greenbelt, Md. On Jan. 13, 2013, at 2:24 a.m. EST, the sun erupted with an Earth-directed 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 reach Earth one to three days later. Experimental NASA research models, based on observations from the Solar Terrestrial Relations Observatory (STEREO) and the ESA/NASA mission the Solar and Heliospheric...

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 mark...

NASA When the Solar and Heliospheric Observatory (SOHO) launched on Dec. 2, 1995, it provided some of the first high-resolution observations of the sun unobscured by Earth's own atmosphere. A joint ESA/NASA mission, SOHO has helped revolutionize our understanding of the sun's interior and complex atmosphere -- home to a variety of giant explosions, including eruptions of solar material known as coronal mass ejections (CMEs). Indeed, before SOHO there was disagreement over what a CME headed...

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...

Lee Rannals for redOrbit.com - Your Universe Online NASA said that the sun emitted a mid-level solar flare on Tuesday that has the potential of causing some radio blackouts. The solar flare reached a classification of M6, which falls into the weakest flares that are still able to cause some space weather effects near Earth. According to the National Oceanic and Atmospheric Association's Space Weather Scales, this M-class flare can cause a radio blackout categorized as R2, or...

Media representatives are invited to attend a ceremony to announce the renaming of NASA's Radiation Belt Storm Probes (RBSP). The event takes place Nov. 9 from 2 p.m. to 3:30 pm EST, at the Johns Hopkins University Applied Physics Laboratory (APL) in Building 200, 11101 Johns Hopkins Rd., Laurel, Md. Along with the announcement of a new name and presentations highlighting the spacecraft's commissioning activities, there will be a tour of the RBSP mission operation facilities. The...

redOrbit Staff & Wire Reports - Your Universe Online On Thursday, October 25, NASA's twin Solar Terrestrial Relations Observatory (STEREO) program celebrated its sixth anniversary orbiting the sun, the US space agency announced on Friday. The twin orbiting probes were launched on that date in 2006, and ultimately entered into similar but separate orbits around the sun. STEREO-A's orbit is slightly smaller and faster, while STEREO-B's is larger and slower, they said, and those subtle...

[WATCH VIDEO: Active Region On The Sun Emits Another Flare] Lee Rannals for redOrbit.com – Your Universe Online NASA said its Solar Dynamics Observatory (SDO) captured the sun erupting with an X1.8 class solar flare on Monday. The solar flare came from an active region on the left side of the sun known as AR 1598, which has been the source of weaker flares. The "X-class" solar flares are the most intense flares, with the number near the X representing its intensity. An X2 class...
