NASA scientists have found the first planet outside of the solar system that could be similar to Earth and capable of sustaining life. Unlike other similarly sized planets, the newly-discovered one lies in a “habitable zone” near a sun-like star. While looking for possibly hospitable planets outside the solar system, the Kepler telescope has recently found a planet some 1,400 light years away,... 

Using our current technology, it would take 180,000 years to reach Zarmina. But our resident physicist Dave Goldberg has a more optimistic estimate – thanks to antimatter and time dilation, astronauts could get there in just a few years. Dave calculates that, if we could build a stellar drive that gets its fuel from matter-antimatter explosions, then it would be possible to travel to Zarmina...
