Intelligent life might be rare
How hard is it for evolution to produce intelligent life like humans? We don't really know, but some computational modelers tried to answer…
The shape of the continents is not a coincidence
Biological processes might have led to greater continental crust coverage than would be expected on a planet without life.
Could impact from asteroids eventually create life?
Astrobiologists have discovered a possible new pathway for the prebiotic self-assembly of biologically important molecules by replicating…

How stars can limit life in the universe
For the past few decades, scientists have been looking at planets outside of our solar system to see if they could host life. Now,…
Could “Fools’ Gold” have helped build the first proteins?
How and why humans exist are questions that have challenged different cultures ever since the dawn of civilization. Many scientists have…
If there was oxygen on a far away planet, how would we know?
Scientists use computer models to simulate what oxygen would look like on far away planets and found a chemical signature that helps us tell…
