Jul 14, 2014 · Many scientists believe we are not alone in the universe. It’s probable, they say, that life could have arisen on at least some of the billions of planets thought to exist in our galaxy alone — just as it did here on planet Earth.

Apr 22, 2024 · Observing signs of possible microbial life in exoplanet atmospheres is currently just out of reach. No convincing evidence of advanced technology – artificial signals by radio or other means, or the telltale sign of, say, massive extraterrestrial engineering projects – has yet crossed our formidable arrays of telescopes in space or on the ground.
6 days ago · It would look like a slam dunk, but Titan would still be toxic to life as we know it. But Titan might have some presence of exotic life, which is another conclusion to this study. While the authors show that the presence of DMS or similar molecules wouldn't prove life exists on a world, they argue that it would indicate a strong potential for life.
May 18, 2020 · Columbia astronomer uses Bayesian statistics to shed light on how extraterrestrial life might evolve in alien worlds. Humans have been wondering whether we are alone in the universe since antiquity. We know from the geological record that life started relatively quickly, as soon our planet's environment was stable enough to support it.
Whether life exists beyond Earth is one of the most profound questions of all time. The answer will change us forever — whether it reveals a universe rich with life, one in which life is rare and fragile, or even a universe in which we can find no other life at all.
Life probably exists beyond Earth. So how do we find it? With next-generation telescopes, tiny space probes, and more, scientists aim to search for life beyond our solar system—and make contact.
The search for life beyond Earth is really just getting started, but science has an encouraging early answer: there are plenty of planets in the galaxy, many with similarities to our own. But what we don’t know fills volumes.
