The South Pole Telescope was constructed during the 2006-07 austral summer. The following winter, the telescope achieved what scientists call “first light” (meaning, it worked), found two quasars (bright objects that may represent massive, radiation-emitting black holes at the center of a galaxy), and spied some small, dark spots that represent galaxy clusters. Now it’s time to start really unraveling the mysteries of the universe.
