... gamma-ray flux; examine large-scale anisotropy of the radiation over angular regions corresponding to galactic features; study quasars, x-ray, and radio sources of small angular size in supernova remnants; measure energy spectra of various galactic radiations; and study time variations of radiation from pulsars, x-ray, and radio sources. Apollo ...

... X-Ray Astrophysics Facility (AXAF), to study stellar structure and evolution, large-scale galactic phenomena, active galaxies and galactic clusters, and cosmology. Chaired by Prof. R. Giacconi of Harvard Univ. and representing ...

... , weighing 340.6 pounds carried an experiment to measure the charge and energy spectra of galactic cosmic rays, and two X-ray astronomy experiments on structure and position of low-energy sources and on fluctuations in X-ray emission from low galactic latitude sources. UK 6 would carry two experiments for the Royal Aircraft Establishment to study ...

... also made the first X-ray photographs of supernova remnants, pulsars, galactic X-ray sources, and diffuse emissions from galactic clusters. Scientists said it would take three years longer to analyze the ...

... . The four investigations in atmospheric science and astronomy were the ionization states of solar and galactic cosmic ray heavy nuclei that would use a new detector system to determine the composition and intensity of ions emitted toward the earth from the sun and other galactic sources; the French astronomy investigation to make an ultraviolet survey of the celestial sphere in ...

... Hopkins Ultraviolet Telescope on Astro-1 would study faint astronomical objects such as quasars, active galactic nuclei, and normal galaxies in the far ultraviolet range; the Ultraviolet Imaging Telescope would record ... of view; and the Wisconsin Ultraviolet Photopolarimetry Experiment would study the polarization of hot stars, galactic nuclei, and quasars. The instruments would make a total of 200 to 300 observations during ...

... years before, the scientists picked up gamma rays-a sure sign that, somewhere near the galactic center, antimatter (protons) was destroyed at a rate of about 10 million tons a second ... astronomers at Berkeley picked out molecules of neon along the line of stars around the galactic center; those furthest from the center were going at the slowest rate, those nearest at ...

... of the University of California at Santa Cruz had described the Milky Way as practicing "galactic cannibalism." Lin explained that the gravitational force of matter in the vast halo encompassing the ... Galaxy was causing the Milky Way to consume the stars and gases of its nearest galactic neighbor, the Large Magellanic Cloud 160,000 light-years away. (NY Times, June 8/93 ...

... likely much older than humankind, their technology likely became capable long ago of exploring their galactic neighbourhood. Their motivation to do so is probably very strong, according to three sets of ... information, answers to major questions, changes in our view of ourselves, and cooperation in joint galactic projects.

... . In order to better illuminate the differences, we consider the duration of Galactic habitability and the notion of 4-dimensional Galactic Habitable Zone. The notion of "rarity" of complex biospheres can be ...
