It is expected that Lunar and Martian explorers will build tools and parts as needed while traveling or using local resources. NASA scientists are interested in testing electron beam freeform fabrication EBF3 on the International Space Station. Such a device could build certified aerospace parts cheaper and using less material than conventional manufacturing methods.in reference to: Device Like 'Star Trek' Replicator Might Fly on Space Station (view on Google Sidewiki)
Astronomers have identified the biggest known black hole in the universe. It is 6.4 billion times more massive than the Sun and lurking 60 million light-years away at the centre of a giant galaxy. The galaxy, called Messier 87 or M87, is a popular target for backyard stargazers in the constellation of Virgo and was suspected to contain a supermassive black hole. Now one of the world's most powerful computers has worked out that the cosmic cannibal is up to three times more massive than thought.
