Deep look at Mars finds no evidence that suggests life-giving liquid is cause of Martian features

Gullies lacing the surface of the Red Planet look similar to the ones that carved out on our planet by flowing water, but a latest deep look at Mars has found no proof that the life-giving liquid was responsible for the Martian features.

Mars surface seems to light up in pastel shades of green, pink, blue, and purple, in a latest picture captured by NASA's Mars Reconnaissance Orbiter (MRO). The colors have shed light on the chemical composition of an area that includes some gullies streaking around the surface like veins.

In a statement, NASA said that though a few scientists had hypnotized that the gullies are made in a style similar to that of gullies on our planet, typically through a process that includes liquid water, latest composition maps of over 100 gully has shed light on no proof of ‘abundant liquid water or its byproducts’ in the shallow channels.

There are some clues that scientists’ posses, which could be help in their attempt to find out how the formation of the Martian gullies have taken place. They could get some information about the comparatively recent geologic activity on mars. As per the NASA statement, “First, the Martian gullies are a widespread and common feature on Mars, mostly between the 30- and 50-degree latitudes in both hemispheres, and generally occur on slopes that face toward the poles”.

The study’s main author, Jorge Núñez of the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, said earlier observation by MRO's powerful High Resolution Imaging Science Experiment (HiRISE) camera demonstrated seasonal activity in gullies.

Seasonal differences in the features of surface have typically suggested that whatever is behind the features was probably experiencing changes linked to temperature fluctuations, like water melting and freezing.
