Magnetic disturbances caused by phenomena like the northern lights can be tracked by a 'social network' of ground-based instruments, according to a new study.

New research shows that the sun could experience a massive burst of energy called a superflare sometime in the next several thousand years.

The celestial phenomenon known as STEVE is likely caused by a combination of heating of charged particles in the atmosphere and energetic electrons like those that power the aurora, according to new research. In a new study, scientists found STEVE's source region in space and identified two mechanisms that cause it.

A new, first-of-its-kind space weather model reliably predicts space storms of high-energy particles that are harmful to many satellites and spacecraft orbiting in the Earth's outer radiation belt.

Solar storms can be far more powerful than previously thought. A new study has found evidence for the third known case of a massive solar storm in historical times. The researchers believe that society might not be sufficiently prepared if a similar event were to happen now.

The Earth's magnetic shield booms like a drum when it is hit by strong impulses, according to new research.

New research shows that the sun's magnetic waves behave differently than currently believed.

On Jan. 4, 2019, at 4:37 a.m. EST the CAPER-2 mission launched from Norway. The rocket flew through active aurora borealis, or northern lights, to study the waves that accelerate electrons into our atmosphere.

Scientists have developed a new technique for looking at historic solar data to distinguish trustworthy observations from those that should be used with care. This work is critical to understanding the sun's past and future as well as whether solar activity plays a role in climate change.

New research describes striking similarity of laboratory research findings with observations of the four-satellite Magnetospheric Multiscale Mission that studies magnetic reconnection in space.

Scientists have demonstrated for the first time that heat from the sun and coldness from outer space can be collected simultaneously with a single device. Their research suggests that devices for harvesting solar and space energy will not compete for land space and can actually help each other function more efficiently.

The solar wind is not a calm summer breeze. Instead, it is a roiling, chaotic mess of turbulence and waves. There is a lot of energy stored in this turbulence, so scientists have long thought that it heats the solar wind. However, the heating expected from turbulence is not the heating observed. Scientists now have a new idea about what heats the solar wind, a theory called magnetic pumping.

School students have successfully identified sounds caused by a solar storm in the Earth's magnetic shield. The group of students identified a series of waves whose pitch decreased over the course of several days. They found that this event occurred after a Coronal Mass Ejection or 'solar storm' caused a great disturbance to Earth's space environment.

Satellites are more likely to be at risk from high-speed solar wind than a major geomagnetic storm according to a new study.
