From: TerryMoselaol.com Date: Mon, 31 Jan 2005 19:54:08 EST Subject: Great CSP, Radio, Lectures, inc IAA meeting Hi all, 1. Congrats to all in the Galway Astronomy Club for running another excellent Connaught Star Party! Once again all the speakers were excellent, including our own Dr Andy McCrea who was asked to cram a 50 minute talk into half an hour, and very nearly did so, with no loss of quality! It was good to see Prof Barry Jones on the go again, after his recent illness. The venue is excellent, & the craic always good. We were also treated to a tour of Prof Mike Redfern's very impressive observatory on the NUIG campus:some very nice kit indeed! Next year they hope to make it a 2-day event. The only down side was that the wrong team won the quiz..... (Well done, John O'Neill, Patricia Carroll & sorry, I can't remember who the third one was!) 2. RADIO: Tues., 1st Feb., 9.30am BBC Radio 4: Relatively Einstein - Terry Pratchett and Ian Stewart on Fantasy Physics See http://www.bbc.co.uk/radio4/science/relativelyeinstein.shtml Thursday 24th February at 4.30pm. "Material World" explores the mysteries of Pluto. You can also listen again to the programme online at www.bbc.co.uk/radio4 for up to 7 days after transmission. 75 years ago a far-flung planet shrouded in mystery was discovered by a fortunate accident. Despite huge advances in astronomy and space travel, many aspects of Pluto still remain a mystery today. Pluto was discovered in 1930 by Clyde W. Tombaugh at Lowell Observatory in Arizona. He had been carefully surveying the sky looking for the mathematically predicted тАШPlanet XтАЩ. Even though the calculations turned out to be incorrect, on the 18th February he discovered the planet Pluto. It was quickly determined that Pluto was too small to account for the orbital discrepancies of the other planets. The search for the elusive Planet X continued but nothing was found. Yet our furthest planet is not alone тАУ Pluto has a moon which is almost the same size as the planet itself. Charon, discovered in 1978, is now thought to have been formed in a similar way to our Moon тАУ by breaking off the Earth after a massive impact with another planet. Some astronomers speculate that Pluto and Charon are really just proto-planets - planets that havenтАЩt fully formed and which may be leftovers from the formation of the Solar System. In Material World this week, Sue Nelson finds out what Pluto might be, and exactly how it was discovered when she talks to Dr. Jacqueline Mitton of the Royal Astronomical Society and astrophysicist Dr. Alan Fitzsimmons at QueenтАЩs University Belfast. Can we really call Pluto a planet? Will a mission to visit this far off world ever take off? How did a little girl from Oxford get to choose the name Pluto? And is there an elusive Planet X still waiting to be discovered? тАЬI suddenly came upon the images of Pluto! The experience was an intense thrill, because the nature of the object was apparent at first sight.тАЭClyde W. Tombaugh 18th February 1930. [We are proud that Dr Fitzsimmons is an IAA member, & has given us many fascinating talks!] 3.
