The First Symposium on Magellan Science (2005) and the Second Magellan Science Symposium (2007) highlighted the excellent performance of the telescopes and just some of the exciting research being conducted on them.
The Magellan main mirrors are f/1.25 paraboloids and a radical departure from the nearly solid-glass mirrors of the past.The.5-meter Baade and Clay telescopes were built by pcv valve toyota manual truck changes the Carnegie Institution of Washington at its Las Campanas Observatory in font .vntime cho win 7 Chile on behalf of the Magellan Project, a collaborative effort by f 16 multirole fighter patch the Carnegie Institution, University of Arizona, Harvard University, University of Michigan, and Massachusetts Institute.Each is 21,000 pounds of borosilicate glass with a lightweight honeycomb structure inside.Astronomers use instruments, such as high-end CCD cameras and spectrographs, to record and analyze incoming light.Every time a large telescope is built, its designers must re-think the challenges, check every application, and improve on what has been done before.Background, large telescopes are custom-built and rare.Relative to their size, the main mirrors are about as thin as a dime.There is no standard practice or model.Each also sits in a "cell" that peforms two important functions.The actual shape of the mirror surface is controlled to within two-millionths of an inch (0.05 microns).The Magellan Consortium consists of more than 200 senior astronomers, 100 postdoctoral astronomers, and nearly 100.
The aluminum surface of each mirror is a mere four-millionths of an inch (0.1 micron) thick.
It took 6 months to build the mold for each mirror, 2 days to fill it with chunks of glass, 1 week to melt the glass and spin it into shape (in a specially designed rotating oven and 3 months for the glass to cool.
The Magellan telescopes were designed with instrumentation as a foremost consideration.Results, the Magellan telescopes began operations in the early part of this decade and have already contributed new data and insights to a wide range of topics in astronomy, cosmology, and astrophysics.The telescopes float on a film of high-pressure oil on a 9-meter diameter circular track.Each was then polished for 8 months while its surface was constantly tested for accuracy.The instrument platforms at Magellan permit rapid switching between different optical configurations in order to take advantage of changing weather, seeing, or moonlight conditions.To prevent slippage, the drive cylinders and drive surfaces are forced together with 10,000 pounds of pressure.Ml ml ml ml ml ml ml ml ml ml ml ml ml ml ml ml ml ml ml ml ml ml ml ml ml ml ml ml ml ml ml ml ml ml ml ml ml ml ml ml ml ml ml.
The telescopes themselves are so well-balanced and frictionless that a gentle push from a child can move all their 150 tons.
