Total solar eclipses, like the upcoming one on April 8, occur on reliable schedules that we can calculate far into the past. This information helps researchers date mysterious events from ancient history.

A gigantic plasma eruption from the sun's hidden far side recently launched a sizable coronal mass ejection that slammed into Mercury, potentially triggering invisible X-ray auroras around the planet's rocky surface.

In 2021, a solar storm was recorded by multiple different spacecraft and the results tell quite the story.

Total solar eclipses make animals behave in strange ways. To see for yourself, stop by one of these zoos located on the path of totality on April 8, 2024.

A solar physicist who accurately predicted that the sun's explosive peak would arrive sooner — and be more powerful — than originally forecast tells Live Science that it may have already begun. However, we won't know for sure until long after it has finished.

Passing stars may have altered Earth's orbit, and its climate, many times throughout cosmic history. New research digs into what that means when it comes to understanding our planet's past.

Sunspot AR3590, which recently spit out three X-class solar flares in under 24 hours, has grown even larger and is now pointed almost directly at Earth, putting us in the crosshairs of more potential eruptions.

A hyperactive sunspot recently unleashed its third X-class flare in under 24 hours. The X6 flare is the most powerful since 2017 and could be followed by equally massive explosions.

Two X-class solar flares arrived at Earth last night and early this morning. The radiation bursts coincided with massive cellphone service outages across the U.S., but experts urge that the events may not be related.

A recent solar flare unleashed a massive plasma plume from the sun's south pole, where these stellar eruptions rarely happen. The unusual phenomenon is a sign of the impending solar maximum.
