Some exoplanets in their stars' habitable zones may be distinctly uninhabitable due to solar flaring. Red dwarfs are known for powerful flaring, and since they're dim and their habitable zones are ...

An unexpectedly strong solar storm rocked our planet on April 23, 2023, sparking auroras as far south as southern Texas in ...

A pair of European satellites have created the first artificial solar eclipses through precise and fancy formation flying. The result is hours of on-demand totality for scientists. The European ...

This colourized image shared by the Solar and Heliospheric Observatory, a joint ESA and NASA project, shows a massive solar eruption that occurred on Nov. 4, 2003, which sent a coronal mass ...

CCOR-1, the world’s first operational, space-based coronagraph, began observing the sun’s corona, the faint outermost layer of the solar atmosphere, on Sept. 19. NOAA/NASA/GOES-19/CCOR-1 ...

The SOHO spacecraft captured amazing imagery of Comet C/2023 A3 (Tsuchinshan-ATLAS) zooming near the sun as the star unleashed a powerful X flare.

One of them was an X flare — the most powerful type of solar flare — and accompanying CME that erupted on Wednesday (Oct. 9) and were recorded by SOHO.

This flare, ranked as X7.1-class, originated from a fast-growing sunspot named AR3842. The X7.1-class solar flare from October 1, 2024, captured by NASA's Solar Dynamics Observatory (SDO).

On that day, an X2.3 flare went off, and the associated coronal mass ejection (CME) rapidly developed into a full halo event, heading for Earth. (NASA/SOHO/AFP via Getty Images) ...
