Large solar storms 'dodge' detection systems on Earth

According to observations from the Tihany Magnetic Observatory in Hungary, the indices used by scientists to assess the Sun’s geomagnetic perturbations to Earth are unable to detect some of these events, which could put both power supply and communication networks at risk. The Tihany Magnetic Observatory registered a solar storm similar to the largest one ever recorded while other observatories were completely unaware of the event.

A comet's tail may shed light on solar wind heating

We can’t see the wind, but we can learn about it by observing things that are being blown about. And by studying changes in a comet’s bright tail of gas and ions, scientists are on the trail to solving two big mysteries about the solar wind, the supersonic outflow of electrically charged gas from the Sun’s million-degree upper atmosphere or corona.

Unexpected role of electrons in creating pulsating auroras

Thanks to a lucky conjunction of two satellites, a ground-based array of all-sky cameras, and some spectacular aurora borealis, researchers have uncovered evidence for an unexpected role that electrons have in creating the dancing auroras. Though humans have been seeing auroras for thousands of years, we have only recently begun to understand what causes them.
