An X1.4 Solar Flare and a CME

A third and fourth flare have erupted from sunspot 1283. The third came on September 7 at 6:36 PM ET, and was categorized as an X1.8 by the GOES spacecraft, making it the second X-class flare within 24 hours.

At 9:35 PM ET on September 5, 2011, the sun emitted an Earth-directed M5.3 class flare as measured by the GOES satellite. The flare erupted from a region of the sun that appears close to dead center from Earth's ...

(PhysOrg.com) -- Late in the evening on June 20 the sun emitted a long lasting C7.7 small class flare that peaked around 11:25p.m. EDT. A C-class flare is a relatively small flare.

The sun let loose with at least six coronal mass ejections (CMEs) -- solar phenomena that can send solar particles into space and affect electronic systems in satellites -- from 7 PM ET on September 18, 2011 ...

Just as sunspot 1105 was turning away from Earth on Sept. 8, the active region erupted, producing a C3-class solar flare (peak @ 2330 UT) and a fantastic prominence.

The Sun unleashed an M-2 (medium-sized) solar flare, an S1-class (minor) radiation storm and a spectacular coronal mass ejection (CME) on June 7, 2011 from sunspot complex 1226-1227. The large cloud of particles ...

It's 1.7 miles long. Its surface is covered in a sticky black substance similar to the gunk at the bottom of a barbecue. If it impacted Earth it would probably result in global extinction. Good thing it is ...

Astronomers from the University of Antioquia have discovered a graveyard of comets. These once-dormant comets, dubbed by astronomers as "The Lazarus comets," are now rejuvenated.

The International Space Station is one of the most complicated machines ever built and the largest object ever assembled in space.

(Phys.org) —Three NASA-built instruments that are integral components of the next in a series of U.S./European ocean altimetry satellites have arrived in France for integration with their spacecraft in ...

Leonardo DiCaprio is going to get closer to stars of a different kind as he heads into space aboard the Virgin Galactic, and a well-heeled bidder at the Cannes Film Festival has paid 1.2 million euros (1.5 million) to be ...

Surrounded by engineers, NASA chief Charles Bolden inspected a prototype spacecraft engine that could power an audacious mission to lasso an asteroid and tow it closer to Earth for astronauts to explore.
