A new ‘agnostic biosignature’ method searches for patterns across exoplanets, suggesting alien life could be detected by how it spreads and reshapes...
New findings from Neretva Vallis, an ancient river channel that once transported water into Jezero crater on Mars, reveal unusually high nickel levels...
Using data from ESA’s Gaia mission and the NASA Exoplanet Archive, astronomers at Cornell University have identified 45 rocky exoplanets in the empirical...
Known non-biological sources, from meteorites to surface chemistry, fall short of accounting for organic compounds detected by NASA’s Curiosity rover,...
A team of researchers led by the University of Wisconsin-Madison has reverse-engineered a primordial nitrogen-fixing enzyme, illuminating how life thrived...
NASA’s Perseverance rover has explored and sampled igneous and sedimentary rocks within Jezero crater to characterize early Martian geological processes...
Although there is no evidence that microorganisms ever existed on Ceres, the results of a new study support theories that this dwarf planet may have once...
Radiolysis induced by Galactic cosmic rays could provide a viable energy source for microbial metabolism in the subsurface environments of rocky planetary...
In a new study, a team of researchers from the University of Manchester performed comprehensive simulations of Earth’s radar systems as potential technosignatures...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have detected the chemical fingerprints of dimethyl sulfide (DMS) and/or dimethyl disulfide...
A team of biologists from the United States, Canada, the United Kingdom and France has developed a scenario of what life on Titan, Saturn’s largest moon,...
White dwarfs may present amenable environments for life on planets formed within or migrated to their habitable zones, generating warmer surface environments...
The field of SETI searches for technosignatures could provide the first detection of life beyond Earth through the technology that an extraterrestrial...
In 1961, American astrophysicist and astrobiologist Dr. Frank Drake devised an equation in which several factors are multiplied together to estimate the...
On Earth, solar radiation can transmit down to multiple meters within ice, depending on its optical properties. Organisms within ice can harness energy...
The TRAPPIST-1 system is a compact system of at least seven exoplanets with sizes similar to Earth. Penn State and SETI Institute astronomers spent 28...
Around a fifth of U.K. citizens believe Earth has been visited by extraterrestrials, and an estimated 7% believe that they have seen a UFO. The figures...
