Scientists Discovered the Previous lake on Mars, Which Might be Preserving Ancient Life

A group of three scientists says they've establish the best place to look for indication of very old life on Mars — one of the youngest lake-bearing basin ever revealed.  However Mars has no liquid water today, the planet was flooded with massive oceans billions of years ago. And as we all know where there's water, there's the possible for life. Researchers think that after the oceans misplaced, that wasn’t just the end for water but for life also. But a new research paper issued in the journal Geology says that's not the case.  Mars had a second reservoir of outside water nearly 3.6 billion years ago — 200 million years after researchers thought Mars had hosted the previous of its liquid water. This water, the scientists report, was found in a lake within a basin near the Martian equator, almost 100 miles from where NASA's Opportunity rover lies today.
It is considered as one of the youngest lakes and thus probably one of the last liquid water sources to still occur on Mars, the scientists report. 
Scientists Discovered the Previous lake on Mars, Which Might be Preserving Ancient Life
The finding is thrilling for the vision of ancient Martian life, clarifies main author Brian Hynek who is a research connect at the Laboratory for Atmospheric and Space Physics at Colorado University-Boulder: Hynek said "Having a later stage of water on Mars is probably a high-quality thing for the potential for life on that planet since it gave life more time to be conceived. There was life on Earth when this lake was active so by that analogy, we can say there's possible that Mars had microbial life and this was a great place where it could have resided." The scientists are studying the age and source of hundreds of salt deposits across Mars to map how a great deal water was present on the surface of Mars.
Using imageries taken by NASA's Mars Reconnaissance Orbiter, which has been circling Mars since-2006, the group deliberate the land and geography around the basin. They found evidence to propose that at one point, the lake developed large enough to fall over the rim of the basin, creating channels in its wake.
The scientists outline these channels to adjacent volcanic plains hundreds of miles absent that are nearly 3.6 billion years old. As the water channels shaped by the lake over-cut the volcanic plains, they have to be younger. That points towards the fact that the lake have to also be younger than 3.6 billion years. Thus far, this lone lake is the only proof of water on Mars about 3.6 billion years- ago. Hynek plans to carry on studying these salt deposit to learn if there's more indication of water on a younger -Mars.
