Jupiter’s intense radiation makes its moon Europa glow

Using a laboratory model, scientists get a nice Jovian surprise.

  • Europa is continually bombarded by radiation from Jupiter.
  • According to new research, that radiation may make the moon glow.
  • The colors of the glow may help scientist identify Europa's compounds.

    • A British scientist named Professor Monica Grady recently came out in support of extraterrestrial life on Europa.
    • Europa, the sixth largest moon in the solar system, may have favorable conditions for life under its miles of ice.
    • The moon is one of Jupiter's 79.

    Neil deGrasse Tyson wants to go ice fishing on Europa

    Everyone loves Europa, says Neil deGrasse Tyson. Why? It's a strong bet for finding life in our solar system, and it's even more amazing because it breaks all the rules.

    Where there is water, there is life—and Europa’s got water alright: scientists believe it has twice the volume of Earth’s oceans swirling beneath its kilometers-thick ice crust. A moon in Jupiter’s massive orbit, Europa has captivated astrophysicists, including Neil deGrasse Tyson, because it has completely blown open the borders in the search for life in our universe. Europa is well outside of the life-supporting "Goldilocks Zone". Tyson explains how liquid water can exist in such a frozen part of our solar system, and how engineers might approach getting through all that ice to potentially come face to face/membrane with life, whether simple or complex. It won’t be too long before NASA’s ‘Europa Clipper’ mission makes its move to investigate the habitability of the icy moon: it will head for Europa in the 2020s. Tyson's new book is Astrophysics for People in a Hurry.

    Hey Bill Nye! Why Don't Gas Giants Have Gas Moons?

    A very small person asks a very big question: why aren't the moons of gaseous planets also made of gas?

    It took a very small person to ask a big question, one that planetary scientists pondered for a long time. There are four gas giants in our solar system – Jupiter, Saturn, Uranus and Neptune – but why are their moons not made of gas? They’re solid, unlike the planets they orbit.
