It was April 24, 1990 when the Hubble Space Telescope left earth for its new home some 350 miles into space. This year we celebrate Hubble's 25 years of service to science and astronomy. In this show we will briefly look back at Hubble's construction and rocky beginning in space. From there we celebrate Hubble's contributions through its mind boggling images and discoveries from our solar system to the deepest reaches in our universe.

Here we are on a planet orbiting one of some two-hundred plus billion stars in our huge city of stars we call the Milky Way Galaxy. We'll look at what makes up our spiral galaxy, where we live in this city of stars, and why it looks the way it does on a dark clear night. We'll then venture out to find and compare our city of stars to other galaxies both near and far; and, onto the basics of the cosmos itself.

Some 6,100 light years from Earth lies a once strange object discovered in 1964 in a constellation called Cygnus. Being located in Cygnus and emitting X-Ray radiation the object was named Cygnus X-1. Today we realize Cygnus X-1 to be a stellar black hole. But what are they? We'll find out as we trace the path to Cygnus X-1 and others from stellar formations to stellar black holes.
