Space Weather
The Sun often produces solar flares and coronal mass ejections, but a rare solar radiation storm made the 2026's first great auroral show.
Launched in March, the PUNCH mission has viewed two incredible coronal mass ejections, tracking them farther from the Sun than ever before.
Sure, there's less daylight during winter than summer, as your hemisphere is tilted away from the Sun. But darkness goes deeper than that.
Northern lights in the American South, clusters of huge geomagnetic storms—the Sun is throwing a tantrum right on schedule.
To know how to protect its astronauts, NASA needs to first understand the threat.
The most iconic, longest-lived space telescope of all, NASA's Hubble, is experiencing orbital decay as the solar cycle peaks. Here's why.
The midwest is particularly filled with them.
Space weather poses a tremendous threat to all satellites, knocking all computer systems offline. Is that a recipe for Kessler syndrome?
Recasting the iconic Carrington Event as just one of many superstorms in Earth’s past, scientists reveal the potential for even more massive eruptions from the sun.
Here on Earth, the Sun is our primary source of light, heat, and energy. But it also poses a grave threat to human civilization.
A Carrington-magnitude event would kill millions, and cause trillions of dollars in damage. Sadly, it isn't even the worst-case scenario.
The largest hazardous asteroid found in the last 8 years showcases a little-known class of planet-killers. And we're woefully unprepared.
1859's Carrington event gave us a preview of how catastrophic the Sun could be for humanity. But it could get even worse than we imagined.
Forty Starlink satellites were destroyed earlier this year in a geomagnetic storm.
And after years of mystery, we finally know where they come from. Here on Earth, thunderstorms and accompanying lightning strikes represent tremendous releases of energy. It was way back in 2011 […]
In 774/775, tree rings show a spike in carbon-14 unlike anything else. At last, scientists think they know why. Every once in a while, science gives us a mystery that comes […]
The NSF’s new, cutting-edge solar observatory shows us the Sun as never before. Here’s why we need to know. On December 12, 2019, the world’s most powerful solar observatory — the National Science […]
Although the great Martian dust storm of 2018 may have ended its life, its accomplishments will live on forever. Note: This article was originally published on January 25, 2019 on Forbes. […]
