...instrument on board the cylindrical observatory is a 1,440-kg (3,200-Ib.) X-ray telescope, which is larger and has higher resolving power than any other ever built. From its perch high above the earth's obscuring blanket of air, it will provide new and sharper images of the myriad and puzzling sources of X rays found across the skies-and new insights into such bizarre phenomena as quasars, pulsars and black holes. As Harvard Astrophysicist Jonathan Grindlay put it: "We are at the dawn of a new era in our understanding of the universe." In honor...
Following the release of its first probe, the Pioneer Venus 2 spacecraft this week was scheduled to toss off three additional instrument-crammed packages. The four probes, as well as the mother ship, will arrive at Venus on Dec. 9. All five are aimed to descend over different areas of the planet, so that they will gather the widest possible range of data, including temperatures, composition, density and distribution of the atmosphere. They will be passing through hostile territory. At higher altitudes the probes will be whipped by winds with velocities that may be as high...

...fated Locarno peace trea ties, in which Belgium, France and Germany agreed never to fight again; American Diplomat Frank Kellogg, who was the originator of the Utopian Kellogg-Briand Pact of 1928, in which 15 powers, including Germany and Japan, agreed to renounce war as an instrument of national policy; and former United Nations Secretary-General Dag Hammarskjöld, who was named posthumously as lau reate in 1961, while his U.N. peace keeping force soldiered on in the bloody morass of the Belgian Congo...
...mirrors have been exposed to what astronomers call "first light," and the new instrument should be operational by early next year. For astronomers, the heavens can hardly wait. Because of MMT'S high and dry desert perch, it should be highly effective in exploring the skies in the largely neglected infra-red portion of the spectrum. These longer wave lengths are especially useful for studying such cosmological mysteries as the birth of stars and the violence in the heart of distant galaxies and quasars that may well be caused by those baffling black holes...
