Using cell phones as space weather vanes

Your smartphone may be able to sense space weather and even get a little disoriented by it, according to researchers, who tested how geomagnetic storms affect the magnetic sensors in cell phones. The new research suggests ...

Solar cycle 25: The sun wakes up

The sun has entered its 25th solar cycle and is about to wake up. For the last few years our star has been pretty sleepy, with few sunspots, bright flares or massive ejections of magnetized plasma emanating from its surface. ...

Breakthrough method for predicting solar storms

Extensive power outages and satellite blackouts that affect air travel and the internet are some of the potential consequences of massive solar storms. These storms are believed to be caused by the release of enormous amounts ...

Magnetic storms: A window to the past

Audrey Schillings recently defended her doctoral thesis about atmospheric loss from Earth and how it varies with solar wind conditions. Audrey was employed at the Swedish Institute of Space Physics and enrolled at Luleå ...

Solar weather has real, material effects on Earth

On Sep. 1, 1859, solar astronomer Richard Carrington witnessed sunspots that suddenly and briefly flashed brightly before they disappeared. Just before dawn the next day, auroras erupted over most of the Earth, reaching as ...

Geomagnetic jerks finally reproduced and explained

The Earth's magnetic field experiences unpredictable, rapid, and intense anomalies that are known as geomagnetic jerks. The mechanisms behind this phenomenon had remained a mystery until the recent discovery of a CNRS researcher. ...
