In a new finding scientists believe the collisions of comet in our solar system increases the chance of life across it. The astrobiologists from the Imperial College in London suggests the violent impacts from comets as well as from other bodies can pepper planets and moons with the molecular building blocks of life.
The new research suggests the high-speed collisions by the comets and other hurtling bodies in the solar system unleash intense shockwaves, which can result in turning simple organic compounds into amino acids.
It is to take note that the amino acids make proteins, cells and in fact all the living organisms.
Scientists said that instead of the collisions having purely destructive force, it increases the odds of life.
Imperial College’s astrobiologist Zita Martins said, “We know that impacts are very common in the solar system, because we can see the craters left behind on different planetary bodies… If impacts occur then more complex molecules can be made, so these building blocks of life could be widespread throughout our solar system.”
The research has been published in the Nature Geoscience journal.
Earlier the scientists had used computer models to demonstrate how these shockwaves works in turning the icy comets’ carbon dioxide, ammonia and methanol molecules into amino acids.
The study found that seven kilometres per second impact produces scores of amino acids.
“Although there are other chemical paths that can generate amino acids, the one we describe can occur during an impact, where no special conditions, such as UV radiation, are required, if the initial ingredients are present”, quoted from the study co-author, Mark Price.
