A newly published study says the moon may have been able to sustain life man years ago.
We may not need to travel far from our home planet to find a spot in our solar system that could once have supported life.
Long ago, Earth’s moon may have had conditions in which life could arise, according to a study published Monday in the journal Astrobiology.
In fact, such conditions could have arisen on the moon during two different periods, each tens of millions of years long, the study suggests. The authors are not saying that life ever existed on the moon — just that the conditions that make life as we know it possible seem to have been in place billions of years ago.
When we look for signs of life on other planets and moons, clues that can indicate a climate supportive to life include liquid water, an atmosphere that would help keep water stable on the surface, a magnetic field offering protection from solar and cosmic radiation, and organic compounds that could make up life’s building blocks.
