In 1995, a pair of scientists discovered a planet outside our solar system orbiting a solar-type star. Since that finding—which won the scientists a portion of the 2019 Nobel Prize in ...

Advanced alien civilizations may communicate via a series of flashing lights, similar to how fireflies do, a new paper hints. This would potentially make extraterrestrials much harder to spot if we ...

Major airports may be alerting intelligent alien civilizations to our presence, according to new research. Are we being watched? Radar systems at major airports may be doing more than managing air ...

After searching 100,000 galaxies for signs of highly advanced extraterrestrial life, a team of scientists using observations from NASA's WISE orbiting observatory has found no evidence of advanced ...

Complex, intelligent life in the galaxy appears vanishingly rare, with the nearest possible civilization perhaps 33,000 light-years distant. Yet despite the odds, scientists insist that continuing the ...

The Drake Equation helps scientists estimate the odds of finding intelligent alien civilizations. It’s an age-old question: Do aliens exist? And what are the odds we’ll make contact? A famous ...

In 1950, famed astrophysicist Enrico Fermi posed a profound question during a casual lunch with colleagues: Where is everybody? In other words, if there’s an extremely high probability that advanced ...

A new paper posits that advanced alien civilizations may communicate through subtle flashes, like fireflies do on Earth. The thought experiment suggests that we need to avoid human biases in our ...
