The Galileo Project was announced a month after the Pentagon released a report about unidentified aerial phenomena, which stated that their nature was unclear. An international team of scientists led by a prominent Harvard astronomer announced a new initiative Monday to look for evidence of technology built by extraterrestrial civilizations. […]

This finding will help scientists refine the search for more advanced life on exoplanets. This NASA-funded research […]

Astrophysicists at LMU have calculated that such systems could harbor sufficient […]

Artist’s illustration of an alien world.   ANIMATION Scientists at Cornell University and the American Museum of Natural History have identified 2,034 nearby star-systems — within the small cosmic distance of 326 light-years — that could find Earth merely by watching our pale blue dot cross our sun. That’s 1,715 star-systems […]

Scientists are at the brink of being able to detect ET Life, which was predicted to be difficult decades ago. New techniques suggest there might be clever analytical tricks using machine learning for doing so. Credit: NASA Scientists have begun the search for extraterrestrial life in the solar system in […]

By varying the initial inventory of volatile elements in a model of the geochemical evolution of rocky planets, researchers obtained a wide range of outcomes, including several scenarios in which a lifeless rocky planet around a sun-like star could evolve to have oxygen in its atmosphere.

Credit: CC0 Public Domain Almost half a century ago the creators of Star Wars imagined a life-sustaining planet, Tatooine, orbiting a pair of stars. Now, 44 years later, scientists have found new evidence that that five known systems with multiple stars, Kepler-34, -35, -38, -64 and -413, are possible candidates […]

This illustration captures an exoplanet as it is about to cross in front of – or transit – its star.

Figure 1: Mars Biosphere Engine. a, The zonally averaged Mars elevation from MOLA8 shows how the formation of the planetary crustal dichotomy has driven hydrology and energy flux throughout geological times, creating both conditions for an origin of life, the formation of habitats, and dispersal pathways. While conditions do not […]
