Scientists from the University of Graz (Austria), Skoltech and their colleagues from the US and Germany have developed a new neural network that can reliably detect coronal holes from space-based observations. This application paves the way for more reliable space weather predictions and provides valuable information for the study of the solar activity cycle. The paper was published in the journal Astronomy & Astrophysics.

The aurora borealis, or northern lights, could easily be described as Earth's greatest light show. A phenomenon that's exclusive to the higher latitudes, has had scientists in awe and wonder for centuries. The theory of how the aurora is created has been speculated but never proven, until now.

Tiny magnetometers have turned your phone into a compass, and new research shows they are sensitive to geomagnetic storms.
