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 ...

Tezpur University study shows how high-energy electrons alter solar oscillations and energy transport, aiding understanding ...

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

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

In a dramatic escalation of solar activity, the sun has unleashed an X8.3 flare — 2026’s strongest yet — causing radio blackouts as scientists monitor Earth-directed CMEs ...

Scientists have long relied on tree rings to learn about ancient solar storms—rare bursts of high-energy particles from the sun that can disrupt satellites, power grids, and communication systems ...

Greetings stargazers. The current sunspot cycle maximum continues to amaze. Several times during the past year, the Aurora ...

The path of 14C from cosmic rays to cellulose. Green arrows denote newer pools of 14C and brown arrows denote older pools. The size of the arrow reflects best estimates of size of the carbon pool.

Space weather has seen a flurry of activity this week. An explosive solar flare that erupted Tuesday, just two days after the ...

After years of work building an exquisitely sensitive instrument, University of Chicago scientists stood and watched as it flew up and out of sight into the fiercely blue Antarctic sky. Launched on ...
