From the time humans have started looking for lives on another planet, our quest and hunger have increased to an extreme level. Every day there exists a new theory and a new prospect of life on the uninhabited planets. Venus, Mars, Europa, Enceladus etc., and many more planets and moons of individual plants show the potential of a possibility of life on them.
By far, the fascinating discoveries for the possibility of life were on Mars – the red plant. Although it is now small, cold and distant from the earth, hope exists that it had a wet past, with a potential of water on their surface for billions of years. Some circumstances prove the possibility of life on Mars, even today.
In this article, we’ve jotted down five such possibilities of life on marks that has changed our scientists’ minds for good.
- The first possibility of life which was discovered from the NASA’s Mars Viking landers, which landed on Mars’ surface in 1976. As a part of the mission, three experiments were performed – a gas release experiment, labeled release experiment and a pyrolytic experiment which was also followed by two other significant experiments – gas chromatography and mass spectrometer experiments. Of all the experiments, only one came out positive, while the others were negative.
- The second was with the use of a par of the Martian Meteorite named Allan Hills 84001. This Meteorite was recovered in 1984, on December 27th. It is said that nearly all the Meteorites that hit the earth are from Mars, and this one was formed billions of years ago and touched the earth’s surface 13,000 years ago. When researched, it showed evidence of the formation of fossils from the carbon remains.
- Third important evidence was from the recent experiment conducted including the Mars rover, that emitted bursts of methane into the air, from unspecified underground locations. Although this was an unambiguous signal, it sure did say something about the support of life.
- Mars’ geography, which contains the Martian landscape, puts earth to shame as it consists of significant hills and valleys that are three times taller than even the Mount Everest. This can also be an inspiration for the research as the life of Marks could be thriving or centuries in the mountain ranges.
- The atmosphere of mars is incredibly thin- if we were to pour a bottle of water on the surface, then it would boil right away, even before it reaches the ground. Even at freezing temperatures on the surface, the air pressure is so low that it cannot hold the water molecules together. However, the scripts’ have discovered that water exists only in one form on the surface – in the form of ice. The location of which is found only in the opposite poles of the planet. However, some shreds of evidence have also stated the possibility of water on the surface. These sceptical studies have made it all the harder to study the existences of life support on the red planet.
