[ Watch the Video ] Lee Rannals for redOrbit.com The sun is a ferocious, hot mess, and this week it showed off through a coronal mass ejection just how messy it can get. An active region on the sun fired off two M-class flares and two coronal mass ejections (CMEs) this week. NASA said the first flare lasted for three hours, and peaked on June 13 at 9:17 a.m. EDT.  The CME associated with the flare traveled up at approximately 375 miles per second. The second flare peaked...

Using data collected by NASA's STEREO spacecraft, researchers at Southwest Research Institute and the National Solar Observatory have developed the first detailed images of solar wind structures as plasma and other particles from a coronal mass ejection (CME) traveled 93 million miles and impacted Earth. The images from a December 2008 CME event reveal an array of dynamic interactions as the solar wind, traveling at speeds up to a million miles per hour, shifts and changes on its three-day...

The largest disturbances to the Earth's geomagnetic environment occur when it is buffeted by solar material hurled in our direction by explosive changes in the Sun's atmosphere. These Coronal Mass Ejections or CMEs contain approximately a billion tons of ionized gas or plasma and can have a dramatic and damaging impact on everything from satellites to power grids. Now a team of scientists have used two spacecraft to study these events in unprecedented detail. Graduate student Anthony Williams...

An international group of solar and space scientists have built the most complete picture yet of the full impact of a large solar eruption, using instruments on the ground and in space to trace its journey from the Sun to the Earth. Dr Mario Bisi of Aberystwyth University will present the team's results, which include detailed images and a movie, on Tuesday April 13th at the RAS National Astronomy Meeting in Glasgow. Coronal mass ejections (CMEs) are giant eruptions of the Sun's atmosphere...

BOULDER -- New research from the National Center for Atmospheric Research (NCAR) links a particular magnetic structure on the Sun with the genesis of powerful solar storms that can buffet Earth's atmosphere. The research may enable scientists to create more accurate computer models of the solar storms, known as coronal mass ejections (CMEs), and could eventually point the way to forecasting the storms days before they occur. Sarah Gibson, a scientist at NCAR's High Altitude Observatory (HAO),...


Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
