The source of potentially hazardous solar particles, released from the Sun at high speed during storms in its outer atmosphere, has been located for the first time by researchers at UCL and George ...

Solar energetic particle (SEP) events and coronal mass ejections (CMEs) are central features of solar activity that significantly influence space weather. SEPs are high‐energy particles expelled ...

The Sun, which provides us with light and heat, is also the site of immense phenomena. In 2017, a powerful solar flare emitted gamma rays whose origin left astronomers puzzled. These emissions seemed ...

Air pollution cut solar electricity generation by 5.8% in 2023, with coal-related aerosols responsible for huge losses in solar power output.

During the Artemis II mission launched Wednesday, NASA will test out a pair of new solar radiation forecasts, developed at University of Michigan Engineering, designed to protect astronauts venturing ...

The star at the center of the solar system does more than provide light and warmth. It also acts as the most powerful particle accelerator in the neighborhood, whipping electrons to near-light speed ...

Southwest Research Institute (SwRI) scientists observed the first close-ups of a source of energetic particles expelled from the Sun, viewing them from just half an astronomical unit (AU), or about 46 ...

New research led by a Southwest Research Institute scientist identified a new source of energetic particles near the sun. These definitive observations were made by instruments aboard NASA's Parker ...

Commonly seen velocity dispersion feature is marked with blue circles in lower energy range observed by Solar Orbiter, while the onset of inverse velocity particles is indicated with orange triangles ...
