That complexity could mean bigger fireworks ahead. With the sunspot now rotating to face Earth, it could pose a threat for ...

The most powerful solar flare unleashed from the sun in nearly five years was triggered by interactions between dark regions on the solar surface that rotate and twist the sun's magnetic field, a ...

Anew sunspot is putting on a spectacular show in our solar system, capturing the attention of astronomers and ...

A new, rapidly growing sunspot is slowly rotating towards Earth, and it could become a hotspot for solar activity in the coming days. On Friday, solar astronomy website Spaceweather.com reported ...

The group of sunspots that created very strong solar flares and intense northern lights has moved around the sun. The sunspot group is now ready to rotate to facing Earth. This could lead to ...

The sun’s magnetic activity causes auroras, and the relationship between solar flares and auroras reveals an 11-year cycle; we’re experiencing a particularly busy one right now.

If they're still safe to use, you can wear them to watch the sunspot groups grow, decay, and rotate into and out of view. "The Sun rotates approximately 13 degrees a day—so enjoy the wonder that ...

A record number of sunspots on the sun as seen on Aug. 8, ... This is due to what is called differential rotation, where the solar equator is rotating much faster than the poles.

Even though the sun's current solar cycle hasn't reached its peak yet, scientists have seen signs that the next 11-year solar cycle is already getting ready for its time to shine.

What makes these two new sunspots so intriguing, though, is that they’re not only massive sunspots, but they’re so large, that they’re changing the way that the Sun vibrates.

It's coming back. In mid-May, the brilliant Northern Lights, or aurora, were visible in places that rarely see them, due to powerful ejections from the sun colliding with Earth. These bursts of ...
