Human missions to Mars are edging closer to reality, but the physics of deep space is not cooperating. Outside Earth’s magnetic cocoon, astronauts would be bombarded by high‑energy particles that can ...

Solar physicists say they have found a key source of intense gamma rays unleashed when Earth's nearest star produces its most ...

Scientists have identified a new source of energetic particles near the Sun. These definitive observations were made by instruments aboard NASA's Parker Solar Probe, which detected the powerful ...

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 ...

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 ...

Mars has been sold as a bold escape plan, a backup world for a species that keeps testing the limits of its first one. The ...

Solar Orbiter has identified the Sun’s dual “engines” for superfast electrons: explosive flares and sweeping coronal mass ejections. By catching over 300 events close to their origin, the mission has ...

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 ...

Solar Orbiter observed more than 300 bursts of ‘Solar Energetic Electrons’ between November 2020 and December 2022. For the first time, we clearly see the connection between the energetic electrons in ...
