(multimedia) During a powerful solar blast on March 7, NASA’s Fermi Gamma-ray Space Telescope detected the highest-energy light ever associated with an eruption on the sun. The discovery heralds Fermi’s new role as a...
(multimedia) NASA has enhanced solar images to make the structures on the sun more visible.
A huge sunspot that dwarfs the Earth is unleashing a series of powerful solar flares as it moves across the surface of the sun, NASA scientists say. The sunspot AR 1476 was detected by...
(multimedia) NASA scientists are watching a group of “monster sunspots,” that may kick up highly charged particles that bombard the Earth. A “monster sunspot” more than 60000 miles wide could send some powerful solar...
Space weather scientists are racing to develop new techniques to predict solar storms that could take down the electricity grid. Good thing, too: the next surge is expected in 2013. The first sign of...
In 2008 in the northern hemisphere of the sun (left) Hinode observed large patches of negative polarity, shown in orange. In 2011, the same area showed much smaller patches and a more even distribution...
(multimedia) A solar flare erupted along the sun’s left side on Monday. The flare was recorded by NASA’s Solar Dynamics Observatory spacecraft, which is part of a 5-year mission focused on the sun. (April...
(multimedia) A key NASA instrument that can directly measure the impact of solar events on the Earth’s upper atmosphere has weighed in on the huge flare that impacted Earth last week. The flare was...
The sun is continuing its active streak this week, firing off another solar flare late Thursday (March 8) from the same region that produced this week’s strong solar storm. An M6.3-class solar flare —...
Britain could be facing another 18 months of potentially disrupted power grids, satellites and flights during a “few rough years of space weather”, according to a leading expert. Space scientist Maggie Aderin-Pocock said there...
