Lethbridge Herald, The (Newspaper) - November 29, 1972, Lethbridge, Alberta -Widntidor, Novimbtr 29, 1972 THE LETHBKIDGE HERALD 33 Radio astronomy had a good year CAMBRIDGE, England 1 (CP) Radio astronomers in Britain are going to look hack on 1972 as one of the best years since the subject starled seriously 30 years ago. Early in the year Sir Martin Ryle received the title of As- tronomer Royal in recognition ot Ills distinguished services to British astronomy. Williin the last few weeks e powerful new radio telescope has come into operation at Cambridge and this will maintain Brit- ain's worldwide lead in cer- tain aspects of the subject. Finally, there was some ex- citement about the discovery of a new radio star by a Cana- dian research group in Sep- tember. Both the Jodrell Bank and Cambridge telescopes have made an indispensable contribution in observing tins nine-day wonder in the heav- ens. The investigation of high-en- ergy processes in galaxies that are up to 10 billion light years from earth is one of the greatest challenges of 20th- century physics. Scientists are puzzled by quasars and radio galaxies: How do they roan- age to sustain their prodigious emission of radio signals over millions of years? One precondition to answer- ing this question is a series of first-rate maps of the radio structures that quasars and galaxies make in the sky. Radio telescopes have to be large to compete with optical instruments. It is impossible to build a radio telescope three miles In diameter as a single instru- ment but Sir Martin Ryle's group at Cambridge has spent 20 years perfecting a tech- nique known as aperture syn- thesis by which a large dish can be built up from an array of smaller ones. In aperture synthesis, the radio signals from space are collected by pairs of aerials for many days. By means of a large computer all this data can be processed in such a way that the information cor- responds to that picked up by i giant telescope. Thus a huge telescope can be constructed In the mind of the computer a graph plotter can be attached so that the radio Images of galaxies which the computer brain builds up can be drawn out. On Oct. 17 Sir Alan Hodgkln, president of [he fioyal Society, opened a new synthesis tele- scope known as the Five-Kilo- metre instrument at Cam- bridge. The 55-million instru- ment consists of eight inter- linked dishes that can be steered to any point in the sky. Stretched across three miles of open country, the eight dishes form the largest telescope of this type in the world. Each day 16 concentric rings of information can be fed into a computer at the observatory, making it possible to draw the radio structures of several sources each week. KESULTS PUBLISHED Observations now are well under way with the telescope, and the first results have al- ready been published. One map shoivs a radio galaxy known as 3C 295; tliis object is five billion light years from earth, farther than any other galaxy. Us radio picture shows two enormous clouds that have been thrown out of the optical galaxy and now are colliding with material in the depths of the universe. The new facility was ready for action when a new radio star burst on the scene at the beginning of September. As- tronomers at the University of Toronto found that an x-ray star known as Cygnus X-3 had increased its radio emission by times in only three days, to become the third brightest object in the sky at radio wavelengths. This is the most dramatic outburst ever witnessed by radio astronomers and the British groups wasted no time in getting all their telescopes trained on it. At Cambridge and Jodrell Bank groups watched the radio flare climb to a peak and then set into a steady de- cline. SAW NEW OUTBURST By Sept. 12 it was all over arrrrar as the observers were concerned. However, the Cambridge group continued to keep watch and their dili- gence was rewarded Sept. 18 when observations registered a 45-per-cent increase in only three hours; here was a new outburst beginning. Soon the intensity rose and the second flare eventually out- paced the first In terms of brightness at Its peak. Jodrell Bank scientists re- cently gave an interpretation of the Cygnus X-3 outburst at a meeting in London. They be- lieve that some tragedy has overtaken the star and caused it to throw a vast cloud of high-energy matter into space. This enigmatic x-ray star cer- tainly is a member of our own Milky Way system and the Cambridge group fix it at be- tween 28 and 40 thousand light years from our solar system, with a diameter for the radio cloud of 20 billion miles. With the new telescope they have pinpointed the position in the sky far more accurately than any other telescope is capable this will as- sist efforts to match the radio source with an optically visi- ble star. Taiwan okay despite politics By LEONARD PRATT TAIPEI (AP) For Taiwan- this has been the year that was. Potential diplomatic disasters, waiting in the wings for two decades, were realized as more more governments found 'themselves unwilling to support !the Idea that the Nationalists the actual government of China. I Taiwan was expelled from the ;United Nations just over a year 'ago. It broke with Japan, its major Asian ally, after Tokyo recognized Peking a month or so ago. More diplomatic breaks seem to lw coming, but the island is used to that now. Few seem to care about the number of em- bassies in toivn as long as that doesn't nffcct the Iwoming econ- omy.

Yet diplomatic reverses have created an unease, a question- ing of national purpose, express- Ing itself in local political prob- lems that, unless solved, could mar the record of economic success. The break with Japan was the biggest shock of a bad year. "That Japan affair was big- ger than the UN vote, even big- ger than Nixon's visit to Pe- king'" one official says. BITTER OVER SWITCH Japan looms large in Taiwan, both to Ihe native Taiwanese who were ruled from Tokyo for 50 years until 1945, and to main- landers who fought Japan dur- ing a long and harsh war. There is still bitterness at the switch of Prime Minister Ka- kiiei Tanaka's government to Peking. Anti Japanese propa- ganda fs on (he television, in magazines and plastered to walls.

COLUMNIST'S NOTEBOOK By HAL BOYLE NEW YORK (AP) _ Things a columnist might never know if he didn't open his mail: The papa emu, the second largest bird in the world, is also probably its best leather- ed father. The only maternal chore of Mrs. Emu is to lay the family eggs. Mr. Emu then sils on them until they hatch, and afterward takes care of Ihe chicks. If you get tired of keeping on your toes all day, how would you like to have to sleep that way? During the reign of Em- p e r o r Charlemagne, beds weren't horizontal but sloped from head to foot so sharply that sometimes the sleeper was standing semi-erect. One of the problems teachers have is that in every group of 100 children there are from five to 10 who have a learning disability or are so hyperactive they require special treatment. Would you like to be guar- anleed a place In heaven for only three days of work? Then yo to Monastir, the beautiful Tunisian seaport. An ancient Moslem legend says that any- one.' who devotes three days to guarding the city's fortifica- tions will, upon his death, im- mediately enter Paradise. It's not a had bargain. An Arab Paradise is out of this world. Odd claims to fame: Singer Bobby Darin Is reported to be the only performer in show bus- iness who has a girl valet. Her name is Terry Koenig, and she's a former school-teacher. Folklore: If you put on a sock inside out, you'll have good luck if you wear it that way all day. If a child's petticoat is longert ban her dress, her moth- er doesn't love her as much as the father does. The best way to get rid of the devil or any other evil spirit is to kneel by jour bedside and say your pray- ers. It's bad luck to leave an empty eggshell in an egg cup.
