Auroras set off a spectacular light show in the night sky, but they also suggest another reason why the ozone layer is depleting.

Although humans are to blame for most of the depletion of the ozone layer,

Which reveals a reason for ozone depletion coming from space:

The charged particles in the plasma by solar flares and coronal mass ejections also continue to gnaw on the ozone layer.

Before now, the effect of these particles was only vaguely known. now,

An international research team has found that the impact of isolated proton aurorae caused a nearly 250-mile-wide (400-kilometer) hole in the ozone layer,

It was just below having an aurora. Most of the ozone disappeared within about an hour and a half.

He said in a statement that researchers did not expect nearly as much ozone depletion in the wake of this event.

Isolated proton auroras may not be as attractive as the northern lights and their southern counterparts,
