The study of cosmic rays and heliospheric physics bridges our understanding of high‐energy particles from distant astrophysical sources and the dynamic environment shaped by the solar wind and ...

The sun's magnetic poles are about to disappear as they swap polarities, which may lead to a number of geomagnetic storms hitting Earth in their wake. The sun's magnetic poles swap positions every 11 ...

Solar flares accelerate energetic electrons that escape into interplanetary space, guided by the Parker spiral magnetic field, and are responsible for the generation of the interplanetary Type III ...

In this historical photo from the U.S. space agency, fully assembled, checked out and fueled for flight, the Solar and Heliospheric Observatory (SOHO) is ready for encapsulation in its protective ...

A strange object flying close to the sun looks unnervingly like a huge, metallic 'mothership' familiar from Hollywood blockbusters. The picture was released by Nasa's sun-watching Solar and ...

An SwRI-led study identified particles accelerated to extremely high energies by magnetic reconnection near the Sun. As NASA’s Parker Solar Probe (trajectory shown in green) crossed the heliospheric ...

"It's not a boring white disk," says solar physicist Bernhard Fleck. Certainly not as seen by SOHO, the Solar and Heliospheric Observatory launched by the European Space Agency and NASA in 1995. SOHO ...
