Our understanding of the cosmos has been revolutionized by the Hubble Space Telescope. The breathtaking familiar photos, like the Pillars of Creation, pale in comparison to the astounding amount of science data returned to Earth. Hubble's getting old, though, serviced several times already, and due for another mission later this year. Let's relive the historic observatory's amazing life so far, and see what the future holds.
Welcome to Astronomy Cast, the most popular astronomy-related podcast. Just look at what listeners have to say about it:
Astronomy Cast is out of this world! It's hard to believe that it's free! This is an absolute must for any amateur astronomer or anyone interested in astronomy or cosmology. The hosts, Pamela and Fraser, are fun to listen to, extremely knowledgeable, and are able to explain difficult subject matter with great analogies. Bravo!
"Very interesting and almost "easy" for amateurs to listen and understand"
I really enjoyed episode 88 about the Hubble Space Telescope. As a new stargazer, I wasn't paying attention to space exploration during most of Hubble's life so it was great to hear some of the history, as well as to find out about the upcoming service mission and the launch of the James Webb 'scope. And as an earth-based observer dreaming of upgrading from my 6" dobsonian to an 8" or 10" computer-controlled 'scope, the possibilities for space-based observation in the invisible spectra just seem fantastic.
As a side anecdote, here is how the name Hubble has become synonymous with far-reaching sight. I work as a motion picture camera operator on films and television. One of our two main camera and lens manufacturers, Panavision, makes a lens officially called the Primo 3:1 Zoom. This is a lens that has only a modest three to one zoom range, but its focal length varies from 135mm at the wide end to 420mm at the long end. On a 35mm film format, this is considered a long telephoto lens. In addition, it has a maximum aperture of f/2.8, making it very useful in low-light situations. Not surprisingly, then, this lens is usually referred to in the industry by its nickname: "The Hubble".
