Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving “magnetic reconnection” – the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion – in the Earth’s magnetotail, the magnetic environment that trails behind the planet.

Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can have – sparking auroras and possibly wreaking havoc on power grids in the case of extremely large events – but they haven’t completely understood the details...
