The search for extraterrestrial intelligence (ETI) has long been a topic of fascination. However, a new study available on the arXiv preprint server introduces a compelling idea about how we might ...

The history of astronomical discovery shows that many of the most detectable phenomena, especially detection firsts, are not ...

If so, why haven’t they said hello? The humble residents of this pale blue dot have been on a quest to find an alien civilisation for more than a century. First, it was the “canals” of Mars. Then ...

Is anybody out there? Probably. Most stars have planets; we've discovered more than 6,000 exoplanets thus far, and the most basic statistics point toward the existence of countless potentially ...

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 ...

The Fermi Paradox, first devised by physicist Enrico Fermi in the 1950s, asks why we haven’t detected alien civilization yet, despite the vast universe teeming with countless potentially habitable ...

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 ...

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 ...

(via Cool Worlds) What is the most realistic way we'll detect an alien civilization? If the history of science and astronomy is any guide, there is a clear answer: The Eschatian Hypothesis.

Renowned astrophysicist Neil deGrasse Tyson continues to dismiss the hypothesis of a Harvard University professor that a massive interstellar object careening toward the sun was sent by alien ...
