Space Weather

It's always sunny for heliophysicists, but especially so now.

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

The spectacular solar storms that paint the polar skies in beautiful greens and pinks have a darker side

South Africa's space agency has existed for just eight years, but the country wants to tackle a crucial challenge in satellite technology: understanding space weather.

Another long-lived NASA mission has come to an end, this one after more than seven years of dancing through the perilous belts of radiation around Earth.

NASA's long-awaited space weather mission is making scientists wait again — ironically, due to terrestrial weather.

NASA hopes that the long-delayed launch of a space weather mission called ICON will finally occur tonight (Oct. 9) — but terrestrial weather concerns may scrub the flight.

An Earth-observing satellite called DSCOVR has been stuck in safe mode for three months, and its operators finally have a plan to reboot it — but not for another few months.

NASA is considering two proposals that would study space weather from the sun, which poses a radiation threat to astronauts cruising across the solar system.

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.
