The ongoing Solar Cycle 25 began in 2019 with a quieter Sun and is predicted to end around 2030. A solar cycle is roughly an 11-year period of the Sun's magnetic activity, from quiet (minimum) to ...

Our sun is about five times less magnetically active than other sunlike stars—effectively a special case. The reason for this could reside in the planets in our solar system, say researchers at the ...

Once-rare displays of Northern Lights at southerly latitudes look set to continue for the foreseeable future as scientists confirmed that August saw the sun at its most active for 23 years. The sun's ...

Interstellar comet 3I/ATLAS, the third object ever confirmed to have originated beyond our solar system, is heading back into deep space on a trajectory that will carry it away from the Sun ...

When the Sun reaches higher levels of activity, junk drifting in low Earth orbit loses altitude at an increased rate — and for the first time, scientists have measured that increase and identified ...

Solar activity as a research area focuses on the study of time-varying phenomena originating from the Sun’s magnetic field, including sunspots, flares, coronal mass ejections, solar wind variability, ...

When you look up at the sky on a sunny day, the Sun might seem like a bright spot, unchanging in the sky. But the Sun is a complex, dynamic celestial body, wrapped in electrical currents and magnetic ...
