Another smoking gun in the search for life in Enceladus' ocean

Today, NASA-funded scientists announced a major new step in the search for life on Enceladus, Saturn’s sixth-largest moon, thanks to new data collected by the NASA/ESA Cassini mission.

  • trappist-1
    Three of the planets in the Trappist-1 system are believed to be in the “habitable zone” for life: close enough to their star to melt ice but not so close that all the water evaporates. In other words, these planets might have liquid water at their surfaces.

    The SETI Institute needs your help to help raise $80,000 to fund this important work. Funds raised this Spring will allow Nathalie and her team to commit to another field expedition this year.

  • Moonlet
    It’s a rock-and-ice piece of ravioli that’s the size of Manhattan, a satellite known as Pan, and one of Saturn’s 62 known moons.
  • Voyager and Pale Blue Dot
    In 1990, the Voyager 1 spacecraft – outbound from the solar system at four times the distance of Saturn – swung its 1500 mm telephoto lens back towards Earth, and snapped a picture.

    The ATA uses 42 radio dishes to search for radio transmissions from ET. How do we know the system is working?

    Astronomers using large optical telescopes in Chile have discovered an Earth-size world around our nearest stellar neighbor, Proxima Centauri.

  • earth proxima
    They would be the closest worlds beyond the solar system. If there are planets around the double star Alpha and Beta Centauri, they’re a mere 4 light-years distant, a remove so small we might actually be able to send space probes there in the foreseeable future.

  • chryse planitia
    Forty years ago, Viking 1 landed on the western slope of Chryse Planitia on Mars. The first spacecraft of two in this twin mission entered Mars’ orbit on June 19, 1976.

  • saturn rings
    For decades, there has been vigorous debate about the age of Saturn’s rings. Are they as old as the planet, or are they relatively new and we’re just lucky to be around at the same time as they are?

  • r2 instrumet
    After 18 months mounted externally on the International Space Station Zvezda module, the European Space Agency Expose-R2 Photochemistry on the Space Station (PSS) experiment was retrieved by cosmonauts during a February spacewalk. The PSS experiment investigated the evolution of organic compounds upon exposure to space radiation.
