Impact craters may have been a toasty home for early life
Heat from a cosmic crash could have nurtured ancient organisms

Meteorites smacking into the early Earth could have created warm, watery environments favorable to primordial life. A new study of an impact crater in Finland suggests that such hydrothermal activity could have lasted up to 1.6 million years — at least 10 times longer than theory suggested, providing plenty of time for life to emerge and spread.
Ancient impact craters on Mars were probably also home to hydrothermal activity, making them good places to search for signs of life, the team repo...
