Astronomers will turn skyward to glimpse ISON, an unusual comet from the outermost edge of our solar system that is now plunging toward the sun. ISON could yield clues to the formation of the solar system, and may become visible to the naked eye in December - if it survives.

China is now leading what some see as a space competition among Asian countries. It has worked on a lunar rover, a space station and an unmanned mission to Mars. India, meanwhile, is about to launch its own Mars mission.

Using special eye-tracking cameras, researchers at the University of Rochester found that many people can perceive their own bodies moving, even in total darkness. Our minds instinctively fill in some images when there aren't any real ones to see.
