The powerful NSF Inouye Solar Telescope has just delivered absolutely mind-blowing observations of its first X-class solar flare.

Coronal loops often appear before solar flares erupt. Flares occur when magnetic fields twist, snap, and reconnect. Until now, telescopes only resolved loop bundles, not individual strands.

Two more of NASA's space telescopes got another look at comet 3I/ATLAS, an interstellar interloper that captured the world's ...

The narrowest magnetic loops ever seen in the sun's corona have been imaged by the most powerful solar telescope on Earth.

Coronal loops are giant arches of superheated plasma guided by the Sun’s magnetic field. These loops can precede solar flares ...
