Alien Life

  • La fotosíntesis mantiene la habitabilidad de la Tierra para la vida tal como la conocemos, y nuestro conocimiento de este proceso biológico condiciona la forma en que buscamos mundos habitables alrededor de estrellas distantes. Ahora los científicos han descubierto un microbio que puede utilizar

  • By observing earthshine, astronomers have observed the Earth as if it were an exoplanet. The study could help identify distant, habitable worlds.

  • Scientists have long thought that planets had to orbit very close to small and dim red dwarf stars in order to be warm enough for life. New research challenges that assumption.

  • Alien planets might experience tidal forces powerful enough to remove all their water, leaving behind hot, dry worlds like Venus.

  • Highly-tilted worlds would have extreme seasons, subjecting life to alternating periods of scorching and subzero temperatures. This could make the development of all but hardiest, simplest creatures a long shot.

  • New observations of the rocky exoplanet, 55 Cancri e, suggest it may be wetter than previously believed.

  • Gravitational interactions between red dwarf stars and habitable planets could erase a world's axial tilt, which moderates global temperatures and creates seasons, before life gets a chance to develop.

  • Rocky moons that orbit gas giant planet and reside in the habitable zone of their star could contain the seeds of life. Thanks to new research, finding those moons just got a little easier.

  • Procurando por Artefatos Alienígenas na Lua
    Dois pesquisadores sugeriram que imagens de alta resolução do Lunar Reconnaissance Orbiter (Orbitador de Reconhecimento Lunar) deveriam ser examinadas para identificar anomalias que poderiam ser evidências de artefatos alienígenas na Lua.
