What Parker Solar Probe Heard Around the Sun.

Explore the fascinating phenomenon of solar flares and their impact on Earth. These flares can affect space weather near Earth, produce harmful radiation, and even cause disruptions to communication systems and power grids.

Describe solar flares and their behavior. What makes the sun throb rhythmically? Describe what will happen when the sun dies. The Powerhouse Sun, Part 3

This was the version submitted to the 2013 Science and Engineering Visualization Challenge. For the original version, with a narration by Liam Neeson, go here:

Like sending sensors up into a hurricane, NASA has flown four spacecraft through an invisible maelstrom in space, called magnetic reconnection. Magnetic reconnection is one of the prime drivers of space radiation and so it is a key...

The sun’s activity will increase significantly over the next four years and will include ‘cannibal’ solar storms that risk knocking out global internet provision.

NASA's STEREO spacecraft and new data processing techniques have succeeded in tracking space weather events from their origin in the Sun's ultrahot corona to impact with the Earth 96 million miles away, resolving a 40-year...

This video features two model runs. One looks at a moderate coronal mass ejection (CME) from 2006. The second run examines the consequences of a large coronal mass ejection, such as The Carrington-Class CME of 1859. These...

On July 23, 2012, a massive cloud of solar material erupted off the sun's right side, zooming out into space. It soon passed one of NASA's Solar Terrestrial Relations Observatory, or STEREO, spacecraft, which clocked the CME as...

Our sun's adolescence was stormy—and new evidence shows that these tempests may have been just the key to seeding life as we know it on Earth.

Our sun's adolescence was cooler than today, but stormy—and new evidence shows that these tempests may have been just the key to seeding life as we know it on Earth.

Learn about the features of the ionosphere! This little-explored region exists between space and Earth. It is home to the aurora, the international space station, a variety of satellites, and radio communication waves. We...

Launched ten years ago, on Oct. 25, 2006, the twin spacecraft of NASA’s STEREO mission – short for Solar and Terrestrial Relations Observatory – have given us unprecedented views of the sun, including the first-ever...

Should we be concerned about solar storms in 2012? Heliophysicist Alex Young from NASA Goddard Space Flight Center sorts out truth from fiction. <b<b<br/>r/>r/>

On August 9, 2011 beginning at 3:48 AM EDT, the sun emitted an Earth-directed X6.9 flare, as measured by the NOAA GOES satellite. These gigantic bursts of radiation cannot pass through Earth's atmosphere to harm humans...

An Earth-directed coronal mass ejection (CME) on Jan. 31, 2013 was accompanied by a large prominence eruption best visible in light with a wavelength of 304 angstroms. NASA's Solar Dynamics Observatory captured this footage from...

Coronal mass ejections (CMEs) and flares are both solar events, but they are not the same. This video shows the differences between the two by highlighting specific features of each. <b<b<br/>r/>r/>

This movie from the Solar Terrestrial Relations Observatory (STEREO) shows comet PanSTARRS as it moved around the sun from March 10-15,2013 (repeated three times). The images were captured by the Heliospheric Imager (HI), an...
