...taking supersharp pictures of space, the go-to telescope is the Hubble, in orbit above the earth. But astronomers can't just use the space telescope whenever they feel like it; they have to bid for time on the badly oversubscribed instrument. After about 2010, when the aging Hubble starts to fail, astronomers won't be able...
Will adaptive optics make space telescopes obsolete? Not entirely. Space is still the best place to take supersharp pictures in ordinary light. And some radiation--ultraviolet, for example, and some wavelengths of infrared--can't penetrate the atmosphere at all. Moreover, telescopes radiate infrared light of their own, which contaminates celestial images. That's why NASA's plan to launch a Next Generation Space Telescope by 2009 still makes sense. With an 8-m mirror of its own, NGST will be able to see distant galaxies, for example, that no earthly telescope could ever see through the glare...
...sets are actually on their way from Sony, RCA, Panasonic and about 10 other manufacturers to showroom floors--and the first digital broadcasts will begin in a little over a month. This much anticipated debut would seem to be terrific news for tube lovers. As promised, the sets deliver supersharp digital pictures, wide-format movie-style screens and magnificent stereo surround sound. And thanks to the content-neutral nature of digital signals--"Bits are bits," they like to say in TV circles these days--you could wind up seeing web pages and e-mail on your HDTV...
...light of revelation, news that the Hubble Space Telescope was flawed appeared to be an unmitigated disaster. Because the telescope's main light-focusing mirror had been precision ground to the wrong specifications, the U.S. had evidently spent $1.5 billion on an instrument that may never take the promised supersharp pictures of the heavens...
