About 14.6 million years ago , a meteorite over half a mile wide blast into the Earth , create a monolithic volcanic crater of melted rock music . Although temperatures there were as high as 36,000 degrees Fahrenheit , investigator have found that life sentence look at storage area there shortly after .
The uncovering — made at the Nördlinger Ries crater , located in Bavaria , Germany — has significant implication for the hunt for life elsewhere in our solar system , since impingement Crater on other planets could serve as worthful fossil situation — the extraterrestrial equivalents of the Burgess Shale Formation .
Until the sixties , scientists were unaware that Nördlinger Ries was in reality a crater . They had previously assumed that the 15 - Swedish mile - full clinical depression had been formed by volcanic activity . Even from blank , the crater is difficult to discern .
That ’s because the abstruse volcanic crater only exist for a few minute . After the initial thaw occurred , the stone cooled quickly to form impact glass , or impactite , which contain various microscopic structures and crystals . The crystalline level of the crater rose up at the middle and collapsed , forming an elevated inner pack . Then , big blocks of rock and roll slid down the volcanic crater bulwark , take in the muddle even further .
Scientists at the Centre for Planetary Science and Exploration at Western University in Canada recentlystudiedthe Ries web site and found enigmatic tubular lineament — approximately one - millionth to three - millionths of a meter in diam — implant within the crystalline rocks . They trust the tubes to be ichnofossils , which are geological record of biologic activity . The researchers surmise that life crept into the crater after the impingement heated groundwater , produce a viable ecosystem .
concord to Gordon Osinski , one of the research worker , meteor wallop craters could serve as unique time capsules , since they once provided an environment for lifeforms to thrive while also keeping records of their existence : “ The saving of biological activity in impact glass has pregnant astrobiological implications for life on early Earth , as well as for the search for life on other planets . ”
