The monolithic asteroid that slammed into Earth some 66 million years ago is often — and understandably — considered a vicious killer . But Modern research into the cosmic effects of the impact advise quite the opposite . That deadly asteroidmight have actually blasted sprightliness throughout the solar arrangement .
As a squad of researchersargue in the late issue of Astrobiology , the so - anticipate Chicxulub impact blasted enough debris into space to spread Earth ’s life as far away as Mars and the Moon of Jupiter . That ’s not even the coolest part , though . The idea of sprightliness be adrift from planet to planet on the backs of asteroid is not a fresh one — it ’s called panspermia — but this newfangled analysis traverse 10 million year of history is the most extended subject field yet .
The thought that lifetime hitched a drive to Mars is pretty far - fetched , of path , and is , at the instant , complete meditation ; but uranologist , for one , seem pretty taken aback by the young enquiry . “ I ’d be surprised if life has n’t begin to Mars , ” Rachel Worth , lead writer of the study , told BBC News . “ It ’s beyond the scope of our cogitation . But it seems reasonable that at some point some Earth organism have made it over there . ”
It ’s also all the more reason to consider that we’reoverprotecting Marsby spend million to sterilize our spacecraft before commit them there . Seems like nature did the chore of contaminating the position for us trillion of years ago . Or was it vice versa ? [ AstrobiologyviaBBC ]
