There are several ways alien life could travel across space, scientists say.
Cosmonaut Anton Shkaplerov lit a wildfire recently when he announced his team had found alien bacteria clinging to the outside of the International Space Station (ISS). It took place during a spacewalk several years ago. Those samples were returned to Earth and have been analyzed recently by Roscosmos—the Russian space agency. He claims Roscosmos scientists conclude the bacteria isn’t from Earth. One thing is for sure, there’s living bacteria clinging to the outside of the ISS! Whether it’s extraterrestrial or not is another matter.
Greatest job ever? NASA will pay six-figures to a Planetary Protection Officer.
New research on Uranus' magnetosphere could help scientists learn about distant systems, and refine the ways they search for alien life.
Uranus has a “switch-like” magnetosphere that opens and closes once every rotation of the planet, exposing it to deadly solar winds, according to researchers at the Georgia Institute of Technology in the US.
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.
