English: In this new Hubblecast episode, Dr. J guides us through the second chapter of Eyes on the Skies, the International Astronomical Union's official movie celebrating the telescope on its 400th anniversary in 2009.
In their quest for ever-fainter objects and finer detail, astronomers have always demanded bigger telescopes. Scientific vision, technical nerve and personal perseverance led to the giant observatories of the early 20th century. Located on remote peaks and protected beneath majestic domes, these awe-inspiring instruments have revealed an expanding and evolving Universe, populated by a stunning variety of galaxies and nuclear powered stars that produced the elements in our bodies. A few decades ago the five metre Hale Telescope on Palomar Mountain seemed to be the ultimate telescope. But was it? Credit:ESA/Hubble (M. Kornmesser & L. L. Christensen) |
