Alien Earths

So far, nearly all of the planets weve found are within the disk of the Milky Way. One world sits in a globular star cluster far above the plane of the Milky Way.  It is the oldest planet known, a 12 billion year relic from the dawn of time. It has an extraordinary story that includes hopping from one star to another and surviving a supernova blast.
NGC joins leading astronomers on a visual journey beyond our solar system in search of planets like Earth. Using CGI animation, we'll explore bizarre worlds that stretch our imagination: planets with iron rain and hot ice, with diamonds everywhere, and endless oceans of gas. Planets with abnormal orbital patterns and planets with no pattern at all that drift alone in the Milky Way. Planets so strange we never could have predicted them before. Could life exist there?
