Fully understanding how a rocky planet becomes habitable and remains so is a fundamental challenge for planetary scientists and astrobiologists, given...
With more than 5,500 detected exoplanets, the search for life is entering a new era. Using life on Earth as a guide, astrobiologists from Cornell University...
Planetary scientists have long speculated about the potential habitability of Venus, not at its hot surface, but in the cloud layers located at 48-60 km...
Saturn’s moon Titan has an organic-rich atmosphere and surface with a subsurface ocean that may represent a habitable environment. In a new study, astrobiologists...
Technosignatures are any measurable property that may provide evidence of extraterrestrial technology. The search for extraterrestrial intelligence (SETI)...
Planets too close to their star are too hot (such as Venus), those too far, are too cold (like Mars), whereas planets in the habitable zone are just right....
Enceladus, the sixth-biggest moon of Saturn, presents a remarkable opportunity in our Solar System for searching for evidence of extraterrestrial life,...
Astronomers from NASA and the University of Washington have estimated total internal heating rates and depths to possible subsurface oceans for 17 planets...
The Whale-SETI team, which includes researchers from the SETI Institute, University of California Davis and the Alaska Whale Foundation, has been studying...
Enceladus is a prime target in the search for life in the Solar System, identified by NASA as the second-highest priority site for a flagship mission in...
In a paper published in the Proceedings of the Royal Society A: Mathematical Physical and Engineering Sciences, researchers at the University of Cambridge...
In the search for life in the Universe, Earth provides a template of evolution for the one habitable planet we know. Earth’s atmospheric composition...
Astronomers from Trinity College Dublin, the Breakthrough Listen project and Onsala Space Observatory have demonstrated the effectiveness of using multisite...
A stable-frequency transmitter with relative radial acceleration to a receiver will show a change in received frequency over time, known as a ‘drift...
Jupiter’s icy moon Europa has an ocean beneath a crust of water ice. Solid carbon dioxide has previously been observed on the surface, but the source...
On September 14, 2023, the NASA Unidentified Anomalous Phenomena independent study team published its final report containing a series of recommendations...
The Search for Extraterrestrial Intelligence (SETI) aims to answer one of the most important scientific questions: are we alone in the Universe? Complementing...
Phosphorus has not previously been detected in oceans beyond those on Earth and this discovery provides a promising step forward in our understanding of...
Plate tectonics is a fundamental factor in the sustained habitability of Earth, but its time of onset is unknown, with ages ranging from the Hadean to...
