Reull Vallis on Mars: Evidence of an Ancient River |
ESA’s Mars Express imaged the striking upper part of the Reull Vallis region of Mars with its high-resolution stereo camera last year.
Reull Vallis, the river-like structure in these images, is believed to have formed when running water flowed in the distant martian past, cutting a steep-sided channel through the Promethei Terra Highlands before running on towards the floor of the vast Hellas basin.
This sinuous structure, which stretches for almost 1500 km across the martian landscape, is flanked by numerous tributaries, one of which can be clearly seen cutting in to the main valley towards the upper (north) side.
The new Mars Express images show a region of Reull Vallis at a point where the channel is almost 7 km wide and 300 m deep.
The sides of Reull Vallis are particularly sharp and steep in these images, with parallel longitudinal features covering the floor of the channel itself. These structures are believed to be caused by the passage of loose debris and ice during the ‘Amazonian’ period (which continues to this day) due to glacial flow along the channel.
The structures were formed long after it was originally carved by liquid water during the Hesperian period, which is believed to have ended between 3.5 billion and 1.8 billion years ago.

The human body is home to trillions of microorganisms, from bacteria to fungi. Some of these perform useful functions for us, like the flora living in our gut that aid gut development and help train the immune system. Even those that have no effect aid us just by being there - they compete for resources with harmful microorganisms like C. difficile, limiting their growth.The yellow column in this photo is a hair, and the green objects are tails. This is a photo of the face mites that live in your eyelashes, eyebrows and hairs in your ears.Demodex folliculorum and Demodex brevis measure around 0.03-0.04mm and live for about two weeks. They are more commonly found on older people than children, as older people produce more sebum (an oily substance produced by the skin to lubricate and waterproof it), which they feed on. They assume a head-in tail-out position in the follicle, but remain able to move between follicles. Though a minority of people can get reactions such as inflammations, most people live in unknowing harmony with these guests. Sources: 1 & 2


That’s really cool. Lol those things are in our eyes
