Black holes have posed some of the
thorniest problems in physics, but
recent research has made exciting
progress. Scientists seem to be on
their way toward resolving the so-
called black hole information paradox,

Astronomers have also taken the first
photograph of the black hole at the
center of the Milky Way.
