The Sun is a complex physical body. It generates incredible amounts of heat and a strong, often tangled, magnetic field.

The sun has become more and more active over the last 16 years, in a turn that surprised scientists and could affect space weather and technology on Earth, NASA announced this week. A new research, ...

Scientists studied how space junk moved in orbit over a 36-year span, finding that increased solar activity caused it to fall to Earth faster.

Stunning imagery from outer space shows the power of the Sun, with a massive solar flare and coronal mass ejection erupting from the giant star’s surface, but space experts say there is no need to ...

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 ...

Has the Sun’s activity increased or decreased in the last few years? This is what a recent study published in The Astrophysical Journal Letters hopes to address as a team of scientists investigated ...

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 ...

When solar activity reached an all-time low in 2008, astronomers reasonably figured the Sun was entering into a period of historically low activity. They were wrong. New research published September 8 ...
