...pinning his hopes on investigating the object's invisible infrared emissions, which have wavelengths slightly longer than the red light at one end of the visible spectrum. Within the next few weeks, astronomers at the Keck Observatory in Hawaii will train a telescope equipped with an experimental infrared spectrograph on the quarry. What it captures could be revealing. "Our hope," says Djorgovski, "is that by seeing the longer wavelengths on the spectrum, we might actually notice a pattern that is familiar...
...clouds of hydrogen gas and dust, 1 million-mph galaxy collisions, and stunning red and blue close-ups of Mars and Neptune. It has also provided valuable evidence for the ongoing debate on the precise age of our universe. Now, with a new near-infrared camera and two-dimensional spectrograph, said NASA's chief Hubble scientist, Ed Weiler, improved picture-taking "is going to get us further back and closer to that answer." Yet it still fell to the scientists, as has become common at NASA, to justify the Hubble's cost. After some quick figuring, Weiler put the annual...
Huchra, who made the telescopic observations for the Harvard-Smithsonian team, used an instrument called a spectrograph to break down each galaxy's light into its constituent colors. Within the spectrum he could see lines representing various elements in and around the galaxy's stars. These lines appear to be shifted toward the red end of the spectrum, depending on how fast the galaxy is moving and thus how far away from earth it is. By carefully measuring the degree of red shift, Huchra and Geller calculated the relative positions of the galaxies...
...them are part of a team that made headlines around the world this winter when it announced the discovery of what appeared to be new galaxies farther out in space and back in time than any other yet seen. Tonight they plan to use the experimental Red Channel Spectrograph, which "sees" deep red light when looking at a galaxy known as M82. Their "eyeball," the spectrograph, is supposed to analyze light that has passed through the telescope, pick out energy in the deep red frequencies coming from the galaxy, and display it on a television screen in symbols that...
...factory worker who knew Ferretti and had been out drinking with the victim the night of the murder. The evidence against Topa was strong but largely circumstantial: bits of wool found on his bloodstained jacket matched the woman's coat. The most striking evidence came from a sound spectrograph, a machine that reduces speech to electronic "pictures" called spectrograms or voiceprints. Lieut. Ernest Nash, Michigan State Police expert, testified at Topa's trial in 1973 that the voiceprint of the telephone confession matched Topa's, not Ferretti's; he also argued that voiceprints were as accurate...
