Space Weather

Auroras offer a wonderful variety of colors and phantasmagoric shapes. A vertical panorama seems to reveal one of these epic moments, with the incredible shape of a bird flying with a running rabbit.

NASA's Parker Solar Probe is preparing for another close swoop by the sun as it celebrates its first year in space.

More than 4,000 photographers shot for the moon (and beyond) for the Astronomy Photographer of the Year competition in the U.K.

NASA will be launching two identical miniature satellites next week as part of a project designed to help scientists understand how Earth's atmosphere muddies the radio signals we rely on.

A high-altitude version of the northern lights can create a headwind for some orbiting satellites, new research confirms.

The blobs are real, they’re chock full of charged particles and they’re heading our way several times each day.

People on Earth are familiar with the sun's powerful rays — but the moon suffers from sunburn, too.

NASA has selected a space weather experiment to fly to the International Space Station as the agency's heliophysics program seeks to strike a balance between large and small missions.

Are those really baby frogs swimming out from the sun? A NASA spacecraft spotted jets shaped like tadpoles in regions of intense solar magnetic activity.

For the first time, an animated model visualized a realistic solar flare.

Where should you go to get the best look at the dancing, dazzling display known as the aurora borealis?

Call it a cosmic coincidence: Two probes launched four decades apart, traveled in opposite directions — and ended up using similar instruments to gather milestone data on precisely the same day.

The Parker Solar Probe is doing well after its first flyby of the sun, and it will soon begin returning groundbreaking data about how our star behaves.

In an effort to better grasp the sun's past, present and future, Colombian and Spanish researchers made visualizations that meld the last 400 years of recorded solar observations.

We can't count on waning solar activity to help bail us out of our climate-change problem in the near future, a new study suggests.

Santa would not do well here.
