After a calm week, the sun erupted again. A powerful M5.1 solar flare burst from an emerging sunspot region, shaking the ...

With the Sun still in an active phase there could be more spectacular Northern light displays in the year ahead.

A sprawling and highly active sunspot complex is turning toward Earth just as a recent solar eruption sends a glancing blow our way, setting up several days of heightened space-weather risk and ...

In the span of two days last week, the sun released two strong solar flares — meaning the solar system experienced its most powerful explosions which can cause some communications blackouts on Earth, ...

The sun unleashed another strong X-class solar flare overnight, stronger than the one that occurred on Tuesday — an X2.7, the strongest so far this year. X-class flares are the strongest and most ...

Surrounding the sun is a vast atmosphere of solar particles, through which magnetic fields swarm, solar flares erupt, and gigantic columns of material rise, fall and jostle each other around. Now, ...

Beautiful yet dangerous solar flares that erupt from the sun could be as hot as 180 million degrees Fahrenheit, researchers say. That's more than six times hotter than solar physicists previously ...

Activity on the sun is not constant; it varies along a cycle of about 11 years. The peak of this solar cycle — called solar maximum — is when sunspots, solar flares and coronal mass ejections (CMEs) ...

A mesmerising side-view video of a massive solar flare goes viral with eerie crackling sounds from real Nasa data.

Plasma astrophysicists at KU Leuven have created the first self-consistent simulation of the physical processes that occur during a solar flare. The researchers used Flemish supercomputers and a new ...
