Many coronal loops — ropey strands of plasma that scientists have long thought existed in the Sun’s atmosphere — may actually be optical illusions, according to a new paper that challenges prevailing ...

From afar, the Sun appears blank and featureless in visible light. But through a solar telescope in different wavelength, it is revealed to be much, much more. In extreme ultraviolet light, the Sun ...

The highest-resolution images of a solar flare captured at the H-alpha wavelength (656.28 nm) ever captured may reshape how we understand the sun's magnetic architecture—and improve space weather ...

It rains on the Sun, the gigantic thermonuclear orb that burns with the multi-million-degree 'fires' of fusion. This rain is made of superheated plasma, and researchers might have discovered its ...

Flickering coronal loops in the Sun's outer atmosphere could act as an early warning system for solar flares, according to new research. Reading time 2 minutes Intense solar flares—sudden bursts of ...

During a close approach to the Sun, the European Space Agency’s Solar Orbiter watched that tipping point unfold in unusually ...

For decades, scientists have tried in vain to accurately predict solar flares—intense bursts of light on the sun that can send a flurry of charged particles into the solar system. Now, using NASA's ...

The Solar Orbiter spacecraft captured outbursts, jets and rivers of plasma beneath the arch of a glowing coronal loop. When you purchase through links on our site, we may earn an affiliate commission.

A record-breakingly sharp image of a solar flare allowed astronomers to get a closer look into the Sun's mysterious coronal loops. Reading time 2 minutes It took astronomers a little over a year to ...

The NSF inouye solar telescope observes its first x-class solar flare and reveals the smallest coronal loops ever imaged MAUI, HI - AUGUST 25, 2025 — The highest-resolution images of a solar flare ...
