The Sun

Three rockets ferrying science instruments will be launched into the eclipse's shadow on April 8. Here's what scientists hope to learn.

On March 28, Earth was hit by an X-class solar flare that was strong enough to ionize part of the planet's atmosphere.

From observing how the sun works to how animals react to darkness in the daytime, here are 4 simple, NASA-funded science projects you can contribute to during the April 8 total solar eclipse.

Though everyone is hoping for clear skies, here's what might happen if an eclipse-chaser's worst enemy — clouds — decides to make an appearance.

For millennia, solar eclipses like the upcoming one on April 8 have inspired awe, wonder and fear. Here are some of the most intriguing accounts of solar eclipses from ancient Greece to the Mayan empire.

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.
