Our Sun may appear calm from Earth’s vantage point, but the space surrounding it is a tumultuous environment. Recent studies, such as one led by the team at theLeibniz Institute for Astrophysics ...

Are the Sun’s most dangerous particles split into just two families? New evidence from the European Space Agency’s Solar Orbiter mission suggests just that and the implications for forecasting space ...

A single gold nanoparticle tends to absorb within a narrow band. Much of its strongest response sits in visible wavelengths.

Close to the sun, the solar wind, a steady stream of charged particles, accelerates until it cannot turn back. During a record pass about 3.8 million miles above the surface, Parker Solar Probe ...

Close-up observations of the Sun explain how solar flares start, grow, and send high-energy particles racing through space.

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 ...

The Sun released a strong solar flare on Tuesday, Feb. 3, following several eruptions in the preceding days, prompting ...

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 ...

Please join the Lowell Center for Space Science and Technology on Thursday, March 27, at 11am for a virtual seminar by Jamie S. Rankin, "Survey of Energetic Particles Viewed by Parker Solar Probe." ...

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 ...

In a dramatic escalation of solar activity, the sun has unleashed an X8.3 flare — 2026’s strongest yet — causing radio ...

Crimson auroras, typically unseen so far south, illuminated the skies of Ladakh's Hanle Dark Sky Reserve on January 19-20.
