Accounting for the buildup of toxic gases predicted to occur in the atmospheres of most planets narrows the habitable zone for complex life by half and, in some cases, rules it out altogether, the study concludes.
A team of scientists has re-created some of the first steps of life in the lab, testing whether life could emerge on other ocean worlds.
Research funded by NASA has led to the creation of an entirely new flavor of the DNA double helix, one that has an additional four nucleotide bases. It's being called hachimoji DNA.
Technosignatures are what we humans would recognize as signs of technologically-advanced activity of an extraterrestrial intelligence.
Trillion Planet Survey is an ambitious experiment, run almost entirely by US students. It uses a suite of telescopes aimed at Andromeda and other galaxies including our own in search for extraterrestrial life.
Technosignatures are signs or signals, which if observed, would allow us to infer the existence of technological life elsewhere in the universe.
Nexus for Exoplanet Systems Science, or NExSS project's mission is to be able detect extraterrestrial “biosignatures” using current and future technologies.
Set to lift off early next week, the Tess spacecraft will prowl for planets around the closest, brightest stars. These newfound worlds will become prime targets for future telescopes looking to tease out any signs of life.
In the Search for Extra-Terrestrial Intelligence (SETI), a team of astronomers recently searched through the Kepler field to look for signatures of technologically-advanced civilizations.
According to a recent study, space dust could be what brought life molecules to Earth. This same mechanism could be responsible for the distribution of life throughout the Universe.
Saturn's sixth-largest moon is incredibly far from the sun, but new research shows that it could probably sustain life.
Australian researchers have detected three of Fast Radio Bursts in just six months using MOST telescope in Canberra, Australia. In doing so, they were able to confirm that these FRBs really do come from outer space.
Newly published research suggests that mysterious phenomena called fast radio bursts could be evidence of advanced alien technology. Specifically, these bursts might be leakage from planet-sized transmitters powering interstellar probes in distant galaxies.
(SETI) alien hunters look for signs of extraterrestrial life in Trappist-1, a newly discovered solar system, by listening to radio surveillance.
A very simple chemical analysis is being developed by NASA scientists that could someday be used by robotic missions on other worlds to detect alien biology.
