This Feb. 4, 2026, image from NASA's Solar Dynamics Observatory (SDO) captures a strong solar flare erupting from the star.

Researchers have proposed that changes in Earth's ionosphere could trigger electrical forces that nudge fragile areas of the ...

Solar physicists and seismologists are testing a provocative idea: that violent outbursts from the Sun could be linked to the timing of some large earthquakes. New statistical work reports ...

The planet is experiencing the most powerful solar event since 2003—and it's bringing spectacular Northern Lights.

The sun is putting on a show. On Sunday the star unleashed several strong and bright solar flares, including one of the most powerful eruptions seen in decades. Far from the steadily glowing orb we ...

A solar storm is a catchall term that describes any disturbance in the sun that involves the violent ejection of solar material into space. This can come in the form of coronal mass ejections, where ...

We could be in for a Northern Light show of epic proportions. A barrage of intense flares erupted from the Sun earlier this week, causing worldwide blackouts and raising the possibility that auroras ...

In a dramatic escalation of solar activity, the sun has unleashed an X8.3 flare — 2026’s strongest yet — causing radio blackouts as scientists monitor Earth-directed CMEs ...

NASA explained that the flares and solar eruptions can impact radio communications, electric power grids, and navigation signals.

New research by Southwest Research Institute (SwRI) and the National Science Foundation's National Center for Atmospheric ...

NASA has reported a X4.2 solar flare, so what does it mean? We break down what a solar flare is and how it connects to the aurora Australis.
