Mercury slammed by gargantuan eruption from the sun’s hidden far side, possibly triggering ‘X-ray auroras’

A gigantic, fiery eruption around 40 times wider than Earth recently exploded from the sun’s hidden far side. The eruption hurled a massive cloud of plasma into space that later smashed into Mercury, scouring the planet’s rocky surface and potentially triggering “X-ray auroras” on the unprotected world.

The eruption was likely triggered by a powerful solar flare, which occurred around 7 p.m. ET on March 9, Spaceweather.com reported. NASA’s Solar Dynamics Observatory (SDO) spotted a large, partially obscured plasma filament exploding outward from behind the sun’s northeast limb. Based on the amount of visible plasma, the eruption likely spanned around 310,000 miles (500,000 kilometers) across.
