A new study is turning the script around the effects of massive meteorite impacts. While an ancient impact is commonly due to the extinction event that killed the dinosaurs, scientists are now starting to suspect that an earlier impact may have triggered life on Earth in the first place.
Scientists have long suggested that meteorites brought the ingredients necessary for life to Earth, but new research suggests that meteorite impacts have also created ideal conditions for life to emerge. The meteorological network relationships. For this reason, scientists suggest that space agencies should pay particular attention to similar craters when hunting for life on the Moon, Mars or beyond.
Immediately after the impact, the area where a meteor crashed on a planet would be hellish and inhospitable. But after things calmed down, these impact craters may have been filled with sediment, nutrients, and even newly created hydrothermal vents, according to research published last week in the journal. Astrobiology.
“They essentially create an oasis for life,”
Osinski added that after billions of years of erosion and other geological activity, it may be impossible to truly find out how life on Earth began, but missions to Mars could seek out similar oases while hunting past or present life.
“There are other impact craters on Mars that would have been best explored with these ideas in mind,” Osinski said in the statement.
