On March 17, 2015, an interplanetary shock – a shockwave created by the driving force of a coronal mass ejection, or CME, from the sun – struck the outermost radiation belt, triggering the greatest geomagnetic storm of...

On September 30, 2014, multiple NASA observatories watched what appeared to be the beginnings of a solar eruption. A filament -- a serpentine structure consisting of dense solar material and often associated with solar eruptions...

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.

In addition to monitoring weather on Earth, the GOES-R satellites will monitor weather in space caused by electromagnetic radiation and charged particles released from solar storms on the Sun. Many people rely on space weather data,...

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...

A team of scientists led by Laura Hayes –a solar physicist who splits her time between NASA's Goddard Space Flight Center and Trinity College in Dublin, Ireland – investigated a connection between solar flares and Earth's...

Our planet is nestled in the center of two doughnut-shaped regions of powerful, dynamic radiation: the Van Allen belts, where high-energy particles are trapped by Earth’s magnetic field. Depending on incoming radiation from the...

A few months before New Horizons was due to reach Pluto, a community of scientists came together to determine just what kind of a environment the mission would experience during its historic flyby. While the simulations aren't 100%...

On Aug. 24, 2014, the sun emitted a mid-level solar flare, peaking at 8:16 a.m. EDT. NASA's Solar Dynamics Observatory and STEREO captured images of the flare, which erupted on the left side of the sun. Solar flares are powerful...

The sun emitted a trio of mid-level solar flares on April 2-3, 2017. NASA’s Solar Dynamics Observatory, which watches the sun constantly, captured images of the three events.

On May 12-13 the sun erupted with an X1.7-class and an X2.8-class flare as well as two coronal mass ejections, or CMEs, off the upper left side of the sun. Solar material also danced and blew off the sun in what's called a...

Watching a particularly beautiful movie of the sun helps show how the lines between science and art can sometimes blur. But there is more to the connection between the two disciplines: science and art techniques are often quite...
