Watch Galaxies & The Expanding Universe

Experience the cosmic wonder of a universe expanding at phenomenal rates, as discovered by Edwin Hubble in the 1920's. Be dazzled by the Hubble Space Telescope's sighting of an incomprehensible number of clustered galaxies throughout the cosmos. This awe-inspiring view of astronomy is put in context by comparisons to the grains of sand on earth and by an imaginary trip to the edge of the known universe and back.

Galaxies & The Expanding Universe is a 2007 special interest movie with a runtime of 14 minutes.
