NASA’s Parker Solar Probe combined efforts with other spacecraft to create the first 2D maps of the Sun’s outer surface, ...

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

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 ...

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, ...

Our sun continues to make news headlines as we’re still in a strong solar cycle that has generated numerous solar flares and coronal mass ejections (CMEs). CMEs are a large release of plasma and ...

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 ...

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

Far above the Sun’s bright surface, a steady stream of charged particles accelerates into space. This outflow, known as the ...

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 ...

"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 ...

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