Is that a spaceship or a cloud?
Although it may seem like an alien mothership, it's actually a impressive thunderstorm cloud called a supercell. Such colossal storm systems
center on mesocyclones -- rotating updrafts that can span several kilometers and deliver torrential rain and high winds including tornadoes. Jagged
sculptured clouds adorn the supercell's edge, while wind swept dust and rain dominate the center.
A tree waits patiently in the foreground.
The above supercell cloud was photographed in July 2010 west of Glasgow, Montana, USA, caused minor damage, and lasted several hours before moving on.

Supercells can produce large hail, damaging winds, deadly tornadoes, flooding, dangerous cloud-to-ground lightning, and heavy rain.
