  • Stellar radiation may preclude Earth-like atmosphere on Proxima b

    Laurel KornfeldAugust 3rd, 2017

    The exoplanet closest to the Solar System, Proxima b, is located in its star's habitable zone but may be unable to support life because radiation from its host star is likely to strip away its atmosphere, according to a new study based on a computer simulation.

  • The Genesis Project: Sending interstellar probes to seed life on exoplanets

    Tomasz NowakowskiOctober 11th, 2016

    German physicist Claudius Gros envisions an interstellar mission that could send microbial life to extrasolar planets that are not permanently uninhabitable. The proposed “Genesis Project” aims to send a fleet of robotic spacecraft equipped with onboard gene laboratories in order to bring life to distant planets with transient habitability.

  • Proxima b may have ocean that could sustain life

    Laurel KornfeldOctober 10th, 2016

    Proxima Centauri b (Proxima b), the exoplanet closest to the Solar System, may be covered by an ocean of liquid water capable of sustaining life.

  • Proxima b could be life-friendly, says co-discoverer

    Tomasz NowakowskiSeptember 5th, 2016

    In late August, the European Southern Observatory (ESO) broke the news announcing the discovery of Proxima b, the closest exoplanet to Earth, fueling hopes of finding an Earth-like planet that could support life. Now, Mikko Tuomi of the University of Hertfordshire, United Kingdom, and co-discoverer of Proxima b, suggests the newly found alien world could be one of the best currently-known extra-solar places to search for microbial organisms.

  • Earth-size planet discovered around nearest stellar neighbor
