Huge eruption on the Sun revisited in spectacular HD

This one may truly knock your socks off. Remember the spectacular filament eruption on the Sun on August 31 that we posted last week? The folks from NASA Goddard's Scientific Visualization Studio now have put out a video ...

Solar storms can destabilize power grids at midlatitudes

The Sun is capable of disrupting electrical systems on Earth in a variety of ways, from solar flares and coronal mass ejections to proton storms. Typically, it is only objects far above the Earth's surface, or systems at ...

ACE, workhorse of NASA's heliophysics fleet, is 15

(Phys.org)—The Advanced Composition Explorer (ACE) is Earth's vanguard. Orbiting around a point 900,000 miles away between the Earth and our sun, this satellite is ever vigilant, recording the combination of radiation—from ...

Sun has "eureka!" moment

(Phys.org)—At the onset of a series of coronal mass ejections (CMEs) on August 20, 2012, this bulbous CME certainly resembled a light bulb. It has the thin outer edge and a bright, glowing core at its center. CMEs are often ...

NASA is tracking electron beams from the Sun

(Phys.org) -- In the quest to understand how the world's weather moves around the globe, scientists have had to tease apart different kinds of atmospheric movement, such as the great jet streams that can move across a whole ...

Solar corona revealed in super-high-definition

Today, astronomers are releasing the highest-resolution images ever taken of the Sun's corona, or million-degree outer atmosphere, in an extreme-ultraviolet wavelength of light. The 16-megapixel images were captured by NASA's ...

NASA sees Sun send out mid-level solar flare

The sun emitted a mid-level solar flare on July 19, 2012, beginning at 1:13 AM EDT and peaking at 1:58 AM. Solar flares are gigantic bursts of radiation that cannot pass through Earth's atmosphere to harm humans on the ground, ...
