Aurora alert! A pair of coronal mass ejections will reach Earth September 1-2, 2021. Though not dangerous to satellites or the grid, they might cause auroras.

Stunning photos of the June 10, 2021 'ring of fire' solar eclipse photos.

The sun's atmosphere, or corona - the wispy part we see during solar eclipses - is hundreds of times hotter than the sun's visible surface, or photosphere. Why?

The moon will sweep in front of the sun June 10 to stage 2021's first solar eclipse. A bright ring, the sun's outer rim, will surround the moon at mid-eclipse.

Researchers uncovering eyewitness accounts of powerful solar storms of the past say we should expect at least one super-storm from the sun per century.

The US Postal Service announced that they'll be releasing a series of stamps highlighting images of the sun captured by NASA's Solar Dynamics Observatory.

NASA's Solar Dynamics Observatory has been continuously observing the sun since its launch in 2010. From its vantage point above Earth, it sees the moon pass in front of the sun 2 to 5 times a year.

A study of oppositely charged magnetic field bands, moving in the sun's northern and southern hemispheres, suggests the coming sunspot cycle - Cycle 25 - will be a particularly strong one. This result contradicts an earlier expert forecast, suggesting a weak Cycle 25.

This video, merging more than 2 decades of footage from SOHO cameras, captures thousands of sunspots, flares, and coronal mass ejections breaking out from the sun.
