That is because intelligent life is likely to form if certain planetary conditions are met, a new study suggests. This idea ...

A popular model of evolution concludes that it was incredibly unlikely for humanity to evolve on Earth, and that extraterrestrial intelligence is vanishingly rare. But as experts on the entangled ...

Intelligent life may develop on planets as a rule, not an exception — increasing the odds of humanity existing beyond Earth, according to a new study.

In one, intelligent life like humans generally arises very quickly on planets, geologically speaking—in perhaps millions of years. In another, it typically arises in about the time it took on Earth.

The path toward intelligent life, they argue, may be more of a predictable process, unfolding as global conditions allow in a manner that should not be considered unique to Earth.

Scientists propose a new idea about why intelligent life hasn't contacted humanity. A planet would need continents, oceans, and plate tectonics for a civilization to emerge in a galaxy.

Intelligent life may be extremely rare in our universe, according to Princeton University Astrophysical Sciences Professor Ed Turner. This view is not surprising, since intelligence is also rare ...

At the same time, the search for intelligent life has turned in a novel direction. In 2018, Frank attended a meeting in Houston whose focus was technosignatures.
