Certainly something to consider as we speculate on how life came to Earth.
Scientists analyzing the halo of the 67P/Churyumov-Gerasimenko comet found that it contains glycine and phosphorous, two of the essential materials necessary for life to form. This discovery further supports the theory that it was comets and other celestial objects slamming into the Earth that enabled life to take hold on our planet. Scientists contend that it takes these essential compounds, water, and some energy to create life.
Why is This Discovery Important?
If these key pieces of the puzzle were delivered to the Earth via comets, then it is highly likely that comets delivered those same pieces to other planets and moons in the solar system. That means that those places where water and energy exist have a higher chance of also having life, albeit likely microbial life, on them.
Where Else Could Life Exist?
Europa
The Hubble Space Telescope detected water vapor off the southern pole of this Jupiter moon. It likely…
