• Life exists in the stratosphere in the form of some biological bacteria.
• It occupies the central region of the atmosphere, and is the second layer of the atmosphere from the ground surface; tropopause separates stratosphere from the troposphere.
• Spy jets fly in the lower layer as the weather conditions there are conducive to flying. In bad weather conditions, or when the fuel is running out, airplanes move up from the troposphere to this layer because the air density is not very dense, and the planes can fly at top speeds without encountering any turbulence.
• Some birds also reach the heights of stratosphere (in the lower part though) and can fly there.
• Daredevil Felix Baumgartner has broken the record for highest-ever sky dive, and also became the first man to intentionally break the sound barrier after jumping from a capsule positioned in the stratosphere – nearly 39 kilometers in the air.

This photographs goes well with a beautiful IDM (intelligent dance music) track from Boards of Canada. Enjoy the Visual Drone 12.
