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 […]

Interior water ocean worlds like Saturn’s moon, Enceladus, are prevalent throughout the universe. New research from Southwest Research Institute suggests that layers of rock and ice may shield life within such oceans, protecting it from impacts, radiation and other hazards and concealing it from detection. Layers of rock and ice […]

An international research team with members from ETH has developed a new method for directly imaging smaller planets in the habitable zone of a neighboring star system. This opens up new possibilities in the search for extraterrestrial life. In the search for planets capable of sustaining life, an international research […]

The Very Large Telescope, or VLT, at the Paranal Observatory in Chile’s Atacama Desert. VLT’s instrumentation was adapted to conduct a search for planets in the Alpha Centauri system as part of the Breakthrough initiatives. This stunning image of the VLT is painted with the colors of sunset and reflected […]
