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 ...

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 ...

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

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.

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

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 ...

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 ...

NASA’s Mars Curiosity rover managed to capture fascinating images of charged particles from a solar storm that hit the planet back in May. The recently shared images show white specks entering the ...
