A 'hole' in the sun's upper atmosphere may soon generate another geomagnetic storm here on Earth, creating auroras in places farther from the poles than usual.

A new NASA eclipse map shows where and when the annular solar eclipse on October 14, 2023, and the total solar eclipse on April 8, 2024, will be visible.

Raise a cold one for the spacecraft as it makes its 15th perihelion today braving blisteringly hot temperatures.

An explosion on the the sun spewed 'dark plasma' into space that resulted in a moderate G2-class geomagnetic storm on Wednesday (March 15).

Astronomers spotted a massive coronal mass ejection (CME) expanding its ethereal wings as it barrelled out of the sun and toward Mercury.

For the next few weeks in March, the sky to the west is illuminated by a pyramid of ethereal glow after twilight known as the zodiacal light.

NASA's Interstellar Boundary Explorer (IBEX) is back to normal operations after controllers successfully reset its computer March 2, NASA said.

The sun blasted out a superpowerful X2-class flare on Friday afternoon (March 3), and a NASA spacecraft captured footage of the dramatic event.

NASA's Interstellar Boundary Explorer (IBEX) reset its flight computer Feb. 18 and has been unresponsive to commands ever since, agency officials said Friday (Feb. 24).

The sun recently spat out an X-class solar flare, one of the most powerful it can emit, which triggered a rare shockwave across the sun's surface and caused radio blackouts on Earth.

Watch Mercury cross in front of the sun's disk in this video captured by the European Solar Orbiter spacecraft.

NASA's NuSTAR telescope has spotted patches of high-energy X-rays radiation across the sun's surface that could explain why the star's atmosphere is mysteriously hot.

One of the instruments on NASA's Parker Solar Probe powered down unexpectedly last weekend, but the mission team expects it to come back online soon.

A massive solar flare erupted from the sun on Friday (Feb. 17) as the Earth was under a geomagnetic storm watch from flares earlier in the week.

The acoustically generated force will help astronomers better understand the sun's photosphere and the causes of space weather.

Minor or G1-class aurora storms may happen overnight in high-latitude areas due to a swarm of particles associated with a big solar outburst on Saturday (Feb. 11).

2023 will have two very special solar eclipses. While the first solar eclipse is incredibly rare, the second is easily accessible to millions of North Americans.

A major solar flare erupted from the erupted from the sun on Saturday (Feb. 11) and a NASA spacecraft caught it on video.

The sun is growing more active in its regular 11-year-cycle and has a huge sunspot serving as a hotbed of flares and other activity.

A huge filament of solar plasma has broken off the sun's surface and is circling its north pole like a vortex of powerful winds, but scientists have no clue what caused it.
