Hi there! I'm sure that if you are interested in space and cosmos you would also like to know about the alein life in the cosmos so I'm here with this blog.
By the title you would have already guessed that I'm going to tell you about Mars. Mars is a "red planet" present in the inner asteroid belt . Till now no conclusive evidence has been found which tell us about past or present life on Mars.Cumulative evidence shows that during the ancient Noachian time period, there would have been surface water on Mars which could contain microebic life. Do you know? if the microebic life on Mars would have survived than Mars would have had hosted intelligent life, just like Earth. So,what led to the extinction of this life? You must not be knowing that like our Earth, Mars also has a tilt but unlikely of earth the tilt is very large, it is of 60°s (approx) which led to unstable rotation of the planet .This large tilt led to disastrous and major change in its seasonal cycle . Due to this large tilt the planet Mars bith orbital and axial rotaions became dramatically unstable, Mars literally had its axis of rotation "rolling" and "twisting"which led to very frequent changes in its seasons and climate which making it extremely difficult even for microscopic life to survive . In this event the majority of microscopic life were gifted to death. But still the bacterias which survived these extreme seasonal condition beneath their protective sheath were finished by fall of a huge asteroid 10.75 million years ago. This asteroid was extremely huge and the strike was so impactful that it deshaped the north pole of mars. The molten magma was spread all over its surface and rised the planet's temperature to no ends .The hit by that large asteroid slowed down the rotational speed of mars and without high rotational speed the molten iron core couldn't generate magnetic field powerful enough (like of our earth's ) to act as a defence system against the very dangerous solar winds and protect the atmosphere . The loss of its magnetic field and then its atmosphere,crushed the hope of a new microscopic life on Mars.
