More evidence of life on Mars but still no life

Scientists are excited Latest geological evidence For the existence of life on Mars. But as we have seen several times in the past, the red planets closely guard our secrets with the possibility of non-life explanation for structures.

As geologist Joel Hurovitz said to us Recent conversation But Quirks and Quarks, The rock firmness in the question was found by the rover which is finding out that once a river delta which was drought in an ancient Martian lake.

Two chemicals found in delta, Vivianite and GreguitMicrobial activity in the soil is often formed on earth – so enthusiasm. But under certain conditions, they can also be formed by chemical reactions. In other words, we have possible evidence for life on Mars, but no decisive evidence.

Mangal has tastylizing us with the possibility of life on our surface as American astronomer Percover Lowell saw through his telescopes in 1894 and thought he saw straight lines to the planet’s criscus.

They called them canals, who are artificial, not naturally formed channels. Lowell believed that these huge characteristics were engineered like the Panama or Suez Canals, but on a very large scale. It was suggested to him that there was a civilization on Mars with amazing technical skills.

Lowell’s claims were fuel for science fiction writers and filmmakers, who were pioneers for stories like HG Wells’ war of the Worlds, Where Earth is attacked by philanthropic martians.

It was not until the 1970s that the Robotic spacecraft debunted the theory of Lowell sent to Mars, revealing a landscape with a landscape, which looked more like the moon than a living planet.

But further robotic exploration discovered drought to the river beds, or channels, which proved that the water was washed away once on the surface billions of years ago.

Where there is water on earth, there is life, so perhaps there was life on Mars. This is not just as a network of cities and canals.

Further compelling evidence came in 1976, when two Viking Landers experimented to search for life in Martian soil. When the soil was heated and fed a drop of thin nutrient solution, it left a gas as if germs were present. But no more experiment finding the organics finding, so it was assumed that the response was chemical, not biological.

Then there was a big fanfare in 1996 about a Martian meteorite found in Antarctica, with a small fossil worm. Finally, the real evidence of Martian life. But again, the geo-ziochemist stepped and declared that the size could also be formed by non-geological procedures.

This debate continues, especially since NASA’s curiosity Rover Recently revealed The largest organic molecule found on Mars till date, which can be pieces of a common component of life seen here on Earth.

Despite the discovery of more than a century, no certain life has been found on the surface of Mars – at least not yet. But what about the possibility of life within the Martian crust?

As Microbial Biochemist Karen Lloyd spoke in his new book, Mutual functional, There is a crowd of life forms that thrive deep underground on earth. The bottom of the surface, the microbial life remains independent of sunlight, remains in the water which leaks through the cracks in the rock.

Mars also contains a permafrost layer that depths the possibility of liquid water where microbial life can grow. This can be a promising place to see.

Recurring over 6,000 verified planets, orbiting other stars beyond Mars, and thousands of candidates are identified as more candidates, many appear hostile surfaces. But this does not mean that life cannot happen. The universe can work with the team with life with life.

NASA recently introduced a new class of astronaut candidates, which will be among those to return to the moon and possibly enter Mars. As they learn to fly the spacecraft and survive on the other world, perhaps they should also get a lesson about how to dig deep holes, so when they land on Mars, they will not only have a flag to apply in the ground, but a drill.
