Life On Mars...Or Not Essay

1351 words - 5 pages

The Heavens. Once an object of superstition, awe and fear. Now a vast region for growing knowledge. The distance of Venus, the atmosphere of Mars, the size of Jupiter, and the speed of Mercury. All this and more we know. But their greatest mystery the heavens have kept a secret. What sort of life, if any, inhabits these other planets? Human life, like ours? Or life extremely lower in the scale. Or dangerously higher ().

There have been numerous counts of scientific evidence that there is life on Mars. But also there has been scientific evidence that goes against this very ideal. The scientific evidence that support that there has been life and it is still there extinct today on this planet has stood the test of time even against other evidence that goes against this ideal.

Last is that the planet must have an atmosphere that is suitable for living organisms. Mars’s atmosphere is weak and it is being blown away by the solar winds form the host star.

Even with the bad temperature, weak atmosphere and said frozen water there still prove that there is life on Mars because there evidence saying that Mars’s living organisms could be sub surface ("'Strongest evidence yet to there being life on Mars'"). The living organisms that are sub surface have the ingredients of life that they need to live. The organisms would be protected from the solar winds, cold temperature and they would have water that the organisms need because the additional pressure would allow water to exist in liquid form and the planet’s interior heat is able to create conditions suitable for Earth-like organisms ("Under the soil on Mars may develop life").
Mars has been sending many tiny meteorites to Earth for thousands of years or may be longer. Also there has been a big debate that Earth has been sending meteorites back to Mars. In one of the meteorite there has been a discovery of tiny carbon -rich balls and tunnels in it. These markings resemble microorganisms leave when they eat through rocks.
