Some of the big moments in tech this past year ranged from space to spacey, and human biology to humanoid robots. Here's a collection of images that represent 2013's big stories, with innovation an overriding theme.
We've chosen the images for their impact. Robots have advanced and become more animalistic or human-like. Private companies have rocketed into space. And some of the images are arty expressions of our world through sculpture and light.
Virgin Galactic's SpaceShipTwo, for example, billed as the world's first commercial space plane, notched an important milestone by firing its rocket engine during flight on April 29. It was a test flight at Mojave Air and Space Port in California.
During the flight, the space-ready passenger space plane detached from its dual-hull mothership, WhiteKnightTwo, at an altitude of 47,000 feet while being piloted by Mark Stucky and Mike Alsbury of builder Scaled Composites.
