Telescоpes оf the FutureJ Whаt’s next? Even bigger telescоpes, of course, with the cаpаbility to shoot cosmic pictures faster, wider, and in even greater detail. Among the behemoths 2 due to come on line within a decade are the Giant Magellan Telescope, the Thirty Meter Telescope, and the 42-meter European Extremely Large Telescope. K Particularly innovative is the Large Synoptic Survey Telescope, or LSST, whose 8.4-meter primary mirror was cast last August in a spinning furnace under the stands of the University of Arizona Wildcats’ football stadium in Tucson. Conventional telescopes have narrow fields of view, typically spanning no more than half a degree on a side—much too narrow to take in the enormous patterns that grew out of the big bang. The LSST will have a field of view covering ten square degrees, the area of 50 full moons. From its site in the Chilean Andes, it will be able to image galaxies far across the universe in exposures of just 15 seconds each, capturing fleeting events to distances of over ten billion light-years, 70 percent of the way across the observable universe. “Since we’ll have a big field of view, we can take a whole lot of short exposures and— bang, bang, bang, bang—cover the entire visible sky every several nights, and then repeat,” says LSST Director Tony Tyson. “If you keep doing that for ten years, you have a movie—the first movie of the universe.” L Tomorrow’s enormous telescopes will do as much in one night as today’s do in a year, but that will not necessarily render the older telescopes obsolete. When the giants come on line, says Gemini astronomer Scott Fisher, “the Geminis of today will become the telescopes that get to go out and do the surveys,” finding interesting phenomena for the largest scopes to investigate in detail. “It’s like a pyramid, and it feeds both ways: When a really big telescope finds something exciting that we can’t spend every night observing, the astronomers can apply for time on a smaller telescope to, say, check it out every clear night for a year and see how it changes over time.” Where will the Large Synoptic Survey Telescope (LSST) be located?
After my Zооm recоrding uploаded to the cloud, I mаde sure the recording link is shаreable and copied and pasted the recording link (AND PASSCODE IF NECESSARY) to the appropriate question in this exam.
