solar flares

A new time-lapse image shows two major sunspot groups moving across the surface of the sun in December 2022, when the number of solar splotches also skyrocketed to an eight-year high.

The flare was accompanied by a coronal mass ejection that missed Earth

One of the events was 80 times more powerful than the strongest solar flare ever recorded.

High-energy eruptions of radiation from the sun's atmosphere can sometimes launch blobs of plasma toward Earth.

NOAA reported that a "moderate" solar storm struck Earth over the weekend, and another once could hit today.

A mixed-up region of sunspots pointed almost directly at Earth just emitted a major solar flare, which could cause havoc with power grids and communication networks.

A powerful solar flare just erupted from the surface of the sun — and NASA captured stunning footage of it.

A restless sunspot sent off a double solar flare on Monday (April 25), temporarily disrupting some radio communications in Asia and Australia.

For the second time in days, the sun hurled a large, X-class flare at Earth, causing radio blackouts and the potential for auroras.

Two immense swarms of sunspots have popped into view on the surface of the sun, hinting at the increased possibilities of vivid auroras and potentially damaging solar flares over the months to come.
