The Sun

A recent X-class flare, which was split into two simultaneous explosions, launched a coronal mass ejection that smashed into Earth, triggering the most powerful disruption to our planet's magnetic field for more than six years.

Cumulus clouds rapidly dissipate as the land surface cools. This isn't just good news for eclipse chasers on April 8, but also has implications for sun-obscuring geoengineering efforts.

Don't have a pair of eclipse glasses to view the April 8 total solar eclipse? No sweat; you can make a safe and simple DIY eclipse viewer with a box, some tinfoil, and a few household craft supplies.

The Spring equinox (March 19, 2024) signals the start of spring in the Northern Hemisphere, the beginning of autumn in the Southern Hemisphere, and a rare moment of "equal night" across the world.

The total solar eclipse on April 8 will offer an incredible view of the fully obscured sun — but some places along the path of totality may see cloudy weather. Here's how to plan for the best view possible.

On April 8, a total solar eclipse will cross North America for the second time in less than seven years. That's not typical; here’s how often solar eclipses occur, and when the next total solar eclipse will be visible.

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.

Bits of glass called Hiroshimaites may have formed by processes similar to those that formed the sun and the planets.

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

Humans aren't the only ones who get spooked during a solar eclipse; animals may change their behavior too, research shows. Here's what to expect on April 8, 2024.
