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

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 ...

Activity on the sun is not constant; it varies along a cycle of about 11 years. The peak of this solar cycle — called solar ...

Scientists have long studied the sun, our solar system’s life-giving star, trying to understand its behavior, solar flares, ...

There are many things with spots: Dalmatians, leopards, ladybugs, overripe bananas, and guys with bald spots are all great examples. Another thing with spots is the Sun! That's right! The Sun, as it ...

Solar Maximum 2025 is the expected peak of solar activity in Solar Cycle 25, characterized by heightened sunspots, solar flares, and coronal mass ejections. This peak is anticipated around mid to late ...

Most places on Earth have seasons because our planet is on a tilt as it orbits the sun. But our star also has its own version of seasons that affect life on Earth—and new astronomical research is ...

Learn what the first maps of the sun's atmospheric boundary reveal about solar wind and its escape into space.

Using the combined might of spacecraft scattered across the Solar System, scientists have built the most detailed map yet of the boundary where the Sun's magnetic push no longer accelerates the solar ...

The sun typically goes through regular cycles of increased and decreased activity, but in recent years, it hasn't been ...

The Sun’s magnetic field is invisible to our eyes, but it quietly shapes everything from the shimmering auroras over the ...

"Terminator" events appear to mark the end of the Sun's solar cycles—and potentially trigger the next wave of activity on the surface of our star. These discoveries could provide a better ...
