World’s Largest Telescope Full Documentary HD

--Welcome to MDoc--

Hunting the Edge of Space In this two-hour special, NOVA examines how a simple instrument, the telescope, has fundamentally changed our understanding of our place in the universe. What began as a curiosity—two spectacle lenses held a foot apart—ultimately revolutionized human thought across science, philosophy, and religion. "Hunting the Edge of Space" takes viewers on a global adventure of discovery, dramatizing the innovations in technology and the achievements in science that have marked the rich history of the telescope.

The Mystery of the Milky Way

"The Mystery of the Milky Way," Hour 1, chronicles the history of telescopes, from Galileo's refractor to Newton's reflector and beyond. It looks at key discoveries, such as those made by William Herschel and his sister Caroline, including the discovery of the planet Uranus. Hour 1 also looks at recent missions: the voyage of the Cassini spacecraft to Saturn, the Kepler telescope's search for planets beyond our solar system, and the Herschel Space Observatory's examination of the Milky Way, which is so large that it would take 100,000 years traveling at the speed of light to cross from one edge to the other. Hour 2, "The Ever-Expanding Universe," introduces a new generation of ever-larger telescopes that is poised to reveal answers to longstanding questions about our universe—and, in turn, to raise new

Thank you for this edifying video. But, I believe that to see the begining of the universe we need the best telescope ever, our brains in order to postulate the dark matter`s role in the formation of the super massive Higgs bosons formed in the gravitationally induced magnetic fields environment that decay into the elementary particles

Its odd how Mars is so much smaller than the earth and yet its surface features seem so much more impressive. But then imagine what the earth would look like with no water. The Marianas Trench would be the new Grand Canyon right? And with no sea level how tall would Everest be? Actually the distance between the deepest point and the highest point is still not as large a number as the height of Olympus Mons I think so no, why are Mars features so much greater than earths?
