... The chances of the Earth being hit by a comet from beyond Pluto ? А la Armageddon ? are much lower than previously thought, according to new research by an ANU astronomer. ... I calculate that small comets, capable of destroying a city, only hit the Earth once every 40 million years or so,? Dr Francis said. ... But asteroids and short-period comets come past again and again, so if we?re clever enough we can find them all and predict which, if any, will hit the Earth,? said Dr Francis. ...

3323. Using Role-playing Games in the Lecture Theatre: An Evaluation
Converting Astronomical Spectra into Sounds: a Tool for Teaching and Outreach? ... In this paper, I present a new way of presenting spectra to the public: convert the electromagnetic spectra into sound spectra and let people listen to them. ... In these cases, the signals being converted to sound are acoustic pressure oscillations: they really are sound waves, simply needing their frequencies to be shifted into the audible range. ... 2 HOW TO TURN SPECTRA INTO SOUNDS: STEP BY STEP GUIDE . ...

3337. Siding Spring Survey AANEAS
In 1990, Duncan Steel, then of the Uni. of Adelaide, commenced the Anglo-Australian Near-Earth Asteroid Survey. This project took advantage of the photographic work being undertaken at the 1.2-m U.K. Schmidt Telescope of the Anglo-Australian Observatory. Since the U.K. Schmidt had commenced its photographic sky surveys in 1973, many comets had been found, but few NEAs. ... The status of the AANEAS and other U. K.
