Scientists Find Microbes Can Survive Traveling from Planet to Planet While Clinging to Asteroids

In an effort to explain how life started on Earth billions of years ago, some scientists have suggested that microbes — or perhaps the organic building blocks of life — may have hitched a ride while clinging to space dust, asteroids, comets, or planetoids. The hypothesis, dubbed panspermia, raises the possibility that the earliest forms of life may have originated on other planets, including perhaps Mars, which scientists believe may have once b…

Martian organisms might have hitched a ride to primordial Earth

A new study has determined that certain life forms are capable of surviving a trip through space on an asteroid. Panspermia is the name given to the h...
