...that when the station pays off with big discoveries? Even then, it's hard to say what the public should expect. NASA's Mars probes, and its orbiting observatories like the Hubble Space Telescope and Chandra X-Ray Observatory, have clearly defined missions, something the ISS lacks. Astronauts can study the long-term effects of weightlessness on their own bones and muscle, as they have since the 1970s, but it's hard to say what benefit will be derived back on Earth. In fact, the first important science study done onboard will try to determine whether the station is even...
Researchers used the sophisticated Chandra X-ray Observatory, an orbiting satellite launched about a year and a half ago by the National Aeronautics and Space Administration (NASA...
...Chandra has cleaner and more precisely aligned mirrors than any other telescope. According to Garcia, the improvement means Chandra can see objects that are 100 times dimmer than what previous telescopes could see--and that difference is enough to detect the factor of 100 in brightness between neutron stars and black holes...
...namesake of the Chandra observatory--Subrahmanyan Chandrasekharan, an Indian astronomer who won the Nobel Prize in 1983 for his work on the evolution of stars--also studied black holes...
...from being just a finder telescope for the Keck, as the piece suggested, the amazing Hubble Space Telescope--arguably the most productive astronomical instrument ever--has been a wellspring for investigations with ground-based telescopes. Indeed, collaboration with the Hubble and other space telescopes, such as the orbiting Chandra and the Space Infrared Telescope Facility, has been a rationale for building these new ground-based telescopes. The synergy between them is a key part of the bright future for astronomical research. ALAN DRESSLER Carnegie Observatories Pasadena, Calif...
