New research finds that volcanoes "scream" at an increasing frequency and then go quiet immediately before they blow.
Programming languages can be intimidating to learn, but researchers at MIT show that it's possible to write programs in plain english—for some things, anyway.
SpaceX recently tested its Grasshopper rocket at a personal record altitude of 1066 feet where it hovered for a few moments before coming back down for a successful recovery landing. The rocket made a first-use of its navigation sensor suite during this flight in order to accomplish its successful precision landing.
The Voyager 1 spacecraft launched in 1977 has traveled more than 11 billion miles from its home world in nearly 36 years and NASA says that it may be nearing interstellar space.
Three planets have been discovered in the habitable zone where liquid water could exist in the nearby star-system, Gliese 667, only 22.1 light years away. This discovery makes these three planets candidates for the presence of life. This also means that with interstellar technologies (i.e. NASA Eagleworks' warp field) currently being developed we could launch a mission to these potentially habitable planets by the end of the century, and the trip would only take a few years.
