"Escaped Life OnThe Planet Mars"

Researchers have found that, much of the red planet "MARS" was might be covered with large oceans. A new study found that  The Red Planet was liveable longer than before scientists has previously discovered it.may be the cosmic impacts might have ended previously on Mars. Scientists have foundthat previously our solar system might have suffered collisions between justborn planets and the revolving pieces of rocks which were left over from the formation of planets later these lumps of planets might had taken form of big stones termed as "Asteroids ".Previously in a research it is suggested that debris from such impact, between our planet Earth and a rock equal in size to that of the Mars named 'Theia' combined and had resulted in the formation of 'Moon'.

Some more works implies thatas the gaint gas planets of solar system had migrated to their current places around the sun, the gravitational pulls of these planets may have launch a bombardment of rocks in the inner solar system world. A late heavy bombardment of such rocks had been further took place in the violent era about 3.8 billion to 4 billion years ago designate the late heavy bombardment.Even scientist from all over the world had deeply debated on this topic not only to discover when that violent epoch might have started or stopped but also whether this happened or not?

Looking on to the knock that planet Earth and Mars have experienced during that time reflects light on the conditions under which life may have developed.Now after having an eye on the oldest know sample of planetary crust in solar system, researchers came out with the fact that heavy bombardment might had not taken place and both the planets The Blue! And The Red! Were adept enough to host life starting earlier than it is previously thought to be.Author Desmond Moser, a Geochronologist at the University of Western Ontario, Canada have even analysed the mineralparticles from meteorites that were crashed in sahara desert and it came up with the result that the impact which blasted these dangerous rocks of Mars likely took place about last 20 million years ago but in previous research it is found that these meteoritesshow the oldest known sample of mars. Even the grains of zircon and other minerals from these meteorites came from the highlands of the planet Mars.

 Moser said that when it is for the age and thickness of the crust then Mars shows wierd differences between its hemispheres this might be due to an impact happened with a large object which could be about 1,000 km in size. Telltale signs took place within rocks due to high pressure and temperature generated by cosmic impact. Study team members said that if giant impacts occur on Mars, they did not occur on planet Earth. "There was No late Large Bombardments sterilizing the earth" and if this is valid, then the habitable pressure and temperatures might have developed 4.2 years ago on both the planets.
