...nearly 14,000 ft. on the summit of the extinct volcano Mauna Kea and is by itself one of the world's biggest and sharpest telescopes; second, the adaptive optics with which the telescope is equipped, which largely cancel out atmospheric blurring; third, the telescope's top-notch coronagraph filter, which blots out most starlight to remove the glare. And finally, the whole thing operates in infrared light, a type of light that renders planets especially bright and sunlike stars relatively dim. In short, says McElwain, "We're using state-of-the-art instruments on a state...
...scientists finally employed an instrument called a coronagraph, which can block out the most blinding light of a star, making a kind of eclipse. With Beta in shadow, Terrile and Smith then attached a special detector to the telescope that picked up the weakest light signals around Beta. The resulting image of an encircling disc looked remarkably similar to our own solar system. Analyzing the configuration of the disc with a computer, they found that some matter may have condensed to form planets...
...specific function of the coronagraph is to determine the wavelength distribution of the corona's ultraviolet rays in order to derive temperatures within the corona...
Kohl said yesterday the coronagraph is expected to be launched in an unmanned sounding rocket in November to an altitude of 100 kilometers where it will gather and simultaneously transmit information...
Kohl said yesterday although the coronagraph is now a "complete instrument." it still needs "minor modifications and performance testing." The group will devote the next eight months to perfecting...
