Spider spiders on Mars, striking optical effect

Spatial probes working in the solar system sometimes provide images to the Earth that, at first glance, seem to represent life forms. The latest is what you see in this news, and was captured on May 13, 2018 by Mars Reconnaissance Orbiter of NASA, orbiting Mars. Shooting, as the space agency explains, frames a detail of the carbon dioxide layer that covers the South Pole region at the end of the Martian winter

at first sight, a group of spiders seems to be coming out, which is why the NASA post was titled " Jamming with the" Spiders "of Mars ". Very suggestive, also because he mentions the name of the group that accompanied him in the 70s David Bowie / Ziggy Stardust (set of the authors of the album The rise and fall of Ziggy Stardust and spiders of Mars ). The black spots in question, however, are not true "spiders", simply a type of ground called "arachneiform", which is formed by heating the carbon dioxide present beneath the surface of Mars. Over time, this trapped gas increases pressure to escape in a jet that burst the dust. The gas is released into the atmosphere and the dust (which is darker than the ground surface) can settle around the vent or be carried by the winds.
