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...
Astronomers using the Murchison Widefield Array in Western Australia have searched for alien signals at a 10 kHz spectral resolution originating from a...
Europa and Enceladus are key targets to search for evidence of alien life in our Solar System. However, the surface and shallow subsurface of these airless...
The last universal common ancestor (LUCA) is the hypothesized common ancestor from which all modern cellular life, from single celled organisms like bacteria...
Within the uncertainties of involved astronomical and biological parameters, the Drake equation typically predicts that there should be many exoplanets...
Ocean worlds are planetary bodies that have a liquid ocean, often under an icy shell or within the rocky interior. In our own Solar System, several moons...
The five artificial greenhouse gases identified by University of California, Riverside astrobiologist Edward Schwieterman and his colleagues would be detectable...
In May 2017, NASA’s Curiosity rover observed higher than usual amounts of manganese in the lakebed rocks within Gale crater, Mars. These sedimentary...
