NASA’s Evolutionary Xenon Thruster (NEXT) project has successfully completed a five-and-a-half-year test of their ion propulsion system, running the engine continuously for over 48,000 hours.
Scottish mathematicians working at the University of Edinburgh have a stark warning for the denizens of Earth: invisible, self-replicating alien robot space probes may be watching us.
How would you like to send your name and a haiku straight to the Red Planet? Who’s it for? Who’s gonna read it when it gets there?

You know what that means! Hercolubus. Wormwood. Planet X. Well, perhaps not. The research was conducted using computer simulations, which …
Don’t make any plans for about four billion years from now. That’s when our distant neighbor, the Andromeda galaxy, will collide with the Milky Way.
