“The images are screenshots from Google Earth. They are glitches that occur when the 2d satellite imagery and 3d terrain don’t line up quite right, or structures such as bridges get projected down onto the terrain below, creating fabulous and unintentional distortions”- Clement Valla

The Physics of Extraterrestrial Civilizations
The late Carl Sagan once asked this question, “What does it mean for a civilization to be a million years old? We have had radio telescopes and spaceships for a few decades; our technical civilization is a few hundred years old… an advanced civilization millions of years old is as much beyond us as we are beyond a bush baby or a macaque.”
Although any conjecture about such advanced civilizations is a matter of sheer speculation, one can still use the laws of physics to place upper and lower limits on these civilizations. In particular, now that the laws of quantum field theory, general relativity, thermodynamics, etc. are fairly well-established, physics can impose broad physical bounds which constrain the parameters of these civilizations.
This question is no longer a matter of idle speculation. Soon, humanity may face an existential shock as the current list of a dozen Jupiter-sized extra-solar planets swells to hundreds of earth-sized planets, almost identical twins of our celestial homeland. This may usher in a new era in our relationship with the universe: we will never see the night sky in the same way ever again, realizing that scientists may eventually compile an encyclopedia identifying the precise co-ordinates of perhaps hundreds of earth-like planets.

Saturn’s hexagon is a persisting six sided cloud pattern around the north pole of the planet. It is created by a band of upper-atmospheric winds, and the sides of it are about 13,800 km (8,600 mi) long, which is longer than the Earth’s diameter. There’s a hurricane swirling within the hexagon.
