Space Weather

Bright, blue flashes stretch from the tops of powerful thunderstorms toward the edge of space, providing a fascinating celestial show for astronauts on the International Space Station.

A strong solar storm recently sparked a whole-planet aurora on Mars more than 25 times brighter than any seen before on the Red Planet, researchers say.

Aurora on Proxima Centauri b may help researchers characterize the planet's atmosphere.

The sun fired off yet another powerful solar flare yesterday (Sept. 10), its seventh in seven days.

A blaze of solar plasma emerges from the surface of the sun in this photo taken of the International Space Station (ISS) as it transited the sun's disk on June 14, 2017.

Solar storms in 2016 may have scrambled the magnetic field sperm whales use to navigate.

Active Region 2673 blasted out yet another solar flare early this morning (Sept. 8), its sixth intense burst of high-energy radiation since Monday (Sept. 4).

An active, sun-spotted region of the sun that unleashed powerful solar flares earlier this week fired two more significant solar flares this morning.

The sunspot that is likely responsible for a monster solar flare that exploded into space yesterday is visible to skywatchers with a pair of solar-viewing glasses.

A solar flare and potential coronal mass ejection could black out some communications.

Early this morning (Sept. 6) the sun released two powerful solar flares — the second was the most powerful in more than a decade.

What's powering the powerful auroras at Jupiter's poles? New results suggest it's not the same mechanism powering the most energetic auroras on Earth, contrary to scientists' expectations.

People as far south as Ohio and Indiana may be able to see the northern lights Wednesday night (Sept. 6), thanks to a powerful sun storm.

Shots of the solar eclipse reveal an active sun.

On Oct. 14, 2014 the Sun blew off a coronal mass ejection (CME) and was detected by the Solar and Heliospheric Observatory (SOHO) and other NASA/ESA probes.
