Back in 2019, a consortium of scientists predicted August 2025 as the peak of the solar activity cycle. But where are we now?

The sun has become more and more active over the last 16 years, in a turn that surprised scientists and could affect space weather, NASA said.

Geomagnetic disturbances caused by solar activity could be increasing the risk of heart attacks here on Earth, according to a ...

North Central and Northwestern states have the best chance of viewing. The peak of the current solar cycle is ongoing, bringing spectacular views of the northern lights to several U.S. states. A ...

For the study, the researchers modeled the influence of “flux ropes,” which are relatively smaller, tornado-like spirals of ...

The sun is in its most active phase—solar summer—causing auroras and posing real risks to satellites, GPS, and power systems on Earth.

Spirals of solar wind can spin off larger solar eruptions and disrupt Earth's magnetic field, yet they are too difficult to ...

Data may challenge and reshape current models of solar wind evolution. A recent study led by Dr. Michael Starkey of the Southwest Research Institute has delivered the first observational evidence from ...

The sun is powered by the nuclear fusion of hydrogen to helium, deep within its core. Above the sun's surface, however, a different force dominates: electromagnetism. This force is responsible for ...
