What happened 14,300 years ago is barely believable. A paper published this week in Earth and Planetary Science Letters details a study of tree rings in the French Alps that reveals evidence of an ...

At the ragged frontier where the Sun’s influence gives way to the galaxy, a decades‑old spacecraft has stumbled into a ...

At the farthest edge of the Sun’s influence, the Voyager probes have stumbled into something that sounds almost mythic: a ...

New research has pinpointed the exact date when the strongest ever solar particle storm hit the Earth. This identification of the event, which occurred in 12,350 B.C., rewrites what scientists ...

Solar flares are among the most violent explosions in our solar system, but despite their immense energy — equivalent to a hundred billion atomic bombs detonating at once — physicists still haven’t ...

New research uncovers the strongest solar event ever detected — rewriting our understanding of space weather and radiocarbon dating. An international team of scientists has discovered an extreme spike ...

Cosmogenic radionuclides, such as 14C and 10Be, are produced in Earth’s atmosphere by interactions with cosmic rays and offer a unique window into past solar variability. Their deposition in natural ...

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 ...

Solar flares are among the most violent explosions in our solar system, but despite their immense energy — equivalent to a hundred billion atomic bombs detonating at once — physicists still haven’t ...
