Chris Impey receives funding from the National Science Foundation and the Howard Hughes Medical Institute. We have only one example of biology forming in the universe – life on Earth. But what if life ...
For decades, many scientists have relied on the "hard steps" model to suggest that intelligent life is rare — the improbable result of a series of unlikely evolutionary leaps. But new research by ...
A Fascinating Theory About a Ring of Asteroids Around Earth Has Some Wild Implications for Evolution
Like many of us, Earth bears old pockmarks. Our planet’s crust has a band of ancient craters that formed around 465 million years ago. The divots were created at a time when animals in the seas were ...
The Cambrian Explosion in which life on Earth underwent massive diversification was likely triggered by eccentricities in Earth’s orbit around our Sun. Or so say the authors of a new paper just ...
