northern lights

Space weather experts warn that a "strong" geomagnetic storm will rock Earth on Sept. 1-2, potentially lighting the skies with vibrant auroras across large parts of North America. The disturbance is being triggered by a rare, cannibalistic ejection from the sun.

A geomagnetic storm could hit Earth Aug. 8 or 9, possibly bringing the dazzling northern lights with it.

A coronal hole in the sun could result in visible auroras over about 15 U.S. states tonight (June 25), with the Space Weather Prediction Center expecting a moderate geomagnetic storm.

NASA's Perseverance rover recently captured a photo of green auroras shining in the Martian sky for the first time. The alien light show, previously assumed to be impossible, could be visible to future astronauts.

Solar eruptions created a northern lights display in North America and Europe overnight, with more auroras expected through Thursday.

The James Webb Space Telescope has successfully detected auroras on Neptune for the first time ever, finishing a job that NASA's Voyager 2 probe began decades ago.

Auroras are possible over the U.S. tonight (March 25) as a "moderate" geomagnetic storm hits Earth.

Expect an uptick in aurora sightings near the spring equinox on March 20, as celestial geometry swings in favor of geomagnetic disturbances.

We know very little about some parts of Earth's atmosphere.
