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.
NASA scientists discover what two places in the solar system might have favorable conditions for alien life.
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.
Peel off your tin-foil hat like a Hershey’s Kiss, because Bill Nye has a reality check for the alien conspiracy theorists out there.
Peel off your tin-foil hat like a Hershey’s Kiss, because Bill Nye has a reality check for the alien conspiracists out there. Roswell? Area 51? Vincent D'Onofrio as the roach alien in MIB? Bill Nye shoos them away, deeming each as unrealistic as the next.
