It was welcome news to Earthlings: The Voyager 1 spacecraft had seemingly crossed a momentous threshold and become the first man-made object to enter interstellar space.
The universe has hidden its age well. The European Space Agency's Planck space telescope has scanned the skies for the Big Bang's fingerprint and discovered that the universe is about 100 million years older than thought, and that there's more normal and dark matter filling the cosmos.
LOS ANGELES - Years of trying to do too many things with too little money have put NASA at risk of ceding its leadership in space exploration to other nations, according to a new report that calls on the space agency to make some wrenching decisions about its long-term strategy and future scope.
