A new study by researchers at Embry-Riddle Aeronautical University, funded by the National Science Foundation, has identified for the first time a process by which the solar wind is heated along extended regions of the Earth's magnetic shield as it penetrates through this barrier.

A solar storm that jammed radar and radio communications at the height of the Cold War could have led to a disastrous military conflict if not for the U.S. Air Force's budding efforts to monitor the Sun's activity, a new study finds.

New findings based on a year's worth of observations from NASA's Van Allen Probes have revealed that the ring current an electrical current carried by energetic ions that encircles our planet behaves in a much different way than previously understood.

The Impact of the Solar Wind

From our vantage point on the ground, the sun seems like a still ball of light, but in reality, it teems with activity.

The New Horizons spacecraft sent back over three years worth of measurements of the solar wind the constant flow of solar particles that the sun flings out into space from a region that has been visited by only a few spacecraft.

Space weather scientist Liz MacDonald has seen auroras more than five times in her life, but it was the aurora she didn't see that affected her the most.

On March 9, 1989, a huge cloud of solar material exploded from the sun, twisting toward Earth.

The geomagnetic storming watch for 30 December has been upgraded to a G3 (Strong), with a G1 (Minor) storming watch still in effect for 31 December.

A Mechanism That halts Solar Eruptions

Among the most feared events in space physics are solar eruptions, massive explosions that hurl millions of tons of plasma gas and radiation into space.

Video: Simulating Space Weather at Pluto

This video shows a simulation of the space environment all the way out to Pluto in the months surrounding New Horizons' July 2015 flyby.

For scientists studying the impacts of space weather, one of the central mysteries of solar flares.

The Sun demonstrates the potential to superflare, new research into stellar flaring suggests.

This winter, two sounding rockets will launch through the aurora borealis over Norway to study how particles move in a region near the North Pole where Earth's magnetic field is directly connected to the solar wind.

New research led by physicists at the University of Warwick has used tools designed to study social networks to gain significant new insights into the Northern Lights, and space weather particularly the interaction of events in the sun's atmosphere with Earth's ionosphere.

Images of a Mid-level Solar Flare Today

The sun emitted a mid-level solar flare, peaking at 3:33 a.m EDT on Aug. 24, 2015.

The universe overflows with repeating patterns. From the smallest cells to the largest galaxies, scientists are often rewarded by observing similar patterns in vastly different places.

NuSTAR Views The X-ray Sun

X-rays light up the surface of our Sun in a bouquet of colors in this new image containing data from NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR.

Sun Unleashes Mid-level Flare

The sun emitted a mid-level solar flare, peaking at 2:23 p.m. EDT on June 22, 2015. NASA's Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event. Solar flares are powerful bursts of radiation.

What began as a chat between husband and wife has evolved into an intriguing scientific discovery.

Our sun is a volatile star: explosions of light, energy and solar materials regularly dot its surface.
