The Earth's magnetic field extends from pole to pole and is strongly affected by solar wind from the sun. This "wind" is a stream of charged particles constantly ejected from the sun's surface. Occasional sudden flashes of ...

Shortly after 4 a.m. on a crisp, cloudless September morning in 1859, the sky above what is currently Colorado erupted in bright red and green colors. Fooled by the brightness into thinking it was an early dawn, gold-rush ...

The Earth's magnetic field, generated some 3,000km below our feet in the liquid iron core, threads through the whole planet and far into space – protecting life and satellites from harmful radiation from the sun. But this ...

Auroras are light shows that typically occur at high latitudes such as the Arctic and Antarctic; however, they can expand toward the equator during severe magnetic storms. Past observations of such unusual auroras can therefore ...

A series of sperm whale strandings saw 29 of the animals beached across the North Sea in early 2016. As these whales are not normally found in the North Sea, the strandings were a bit of a mystery. But a study is now proposing ...

Our ever-changing sun continuously shoots solar material into space. The grandest such events are massive clouds that erupt from the sun, called coronal mass ejections, or CMEs. These solar storms often come first with some ...

New research on solar storms finds that they not only can cause regions of excessive electrical charge in the upper atmosphere above Earth's poles, they also can do the exact opposite: cause regions that are nearly depleted ...
