The Sun has just unleashed an M5-class solar flare, a powerful burst of radiation that signals a clear uptick in solar activity as the current cycle heads toward its peak. While this event is not the ...

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.

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 ...

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) ...

The alignment of the Sun and Earth during the spring and autumn equinoxes can slightly increase activity, known as the ...

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 ...

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, ...

The mystery of a stellar flare a trillion times more powerful than the largest of solar flares may have been solved by a team of scientists who believe a massive young planet is burning up in a ...
