It is believed that a cosmic storm nearly ended life on Mars for good – information that leads scientists to the conclusion that their previous beliefs were wrong. This new theory has the planet being able to sustain life for a more extended period than previously thought. Newly formed planets and roaming asteroids most probably collided with each other during the early formation of the solar system. Mars, however, seems to have escaped a massive asteroid impact 4.4 billion years ago, and life on Mars started to flourish.
The giant pieces of rock from the interplanetary debris went on to roam space known as asteroids. An example of such an ancient impact is the one between Earth and another planet. Scientists believe that a planet with a size equal to Mars named Theia collided with Earth. This may have resulted in the formation of the Moon.
It is being said that the migration of the gas giant planets towards the Sun’s orbit had severe consequences. This violent move into having a stable orbit may have dislodged a massive amount of rocks towards the planets closer to the Sun.
Mars Escaped Massive Asteroid Impact 4.4 Billion Years Ago, Which Promoted Life On Mars To Flourish
This period in time has been designated as the Late Heavy Bombardment and happened around 3.8 to 4 billion years ago. However, scientists do not agree about the timeframe of these events or even whether it happened at all. If true, this period in time could tell us much about the evolution of the solar system that has led to the current situation we find ourselves in.
That would be able to reveal what lead to some planets favoring life and also the point where they were not able to do so anymore. But once again, there is no agreement.
Some say that the system altering event did not take place after studying the oldest known sample of planetary crust. Mineral grains from meteorites that landed in the Sahara were analyzed. It is believed that these meteorites are of Martian origin and crashed here about 20 million years ago. By studying them, researchers concluded that life on Mars might have flourished about 4.4 billion years ago, as the Red Planet escaped doom, namely, a massive asteroid impact.
