Castalia . Asteroid 4769 . Asteroid 4769 Castalia is a near-Earth crossing asteroid that was discovered by Eleanor F. Helin (Caltech) on August 9, 1989. Scientists used radio astronomy and computer modeling to generate this image of Castalia. They obtained the data for the computer model in 1989 using the Arecibo radar/radio telescope in Puerto Rico when the asteroid passed within 5.6 million kilometers (3.5 million miles) of the Earth. ...

The aim of this section of the course is to enable you to use simple computer programs to solve a variety of common astronomical tasks. ... I have (somewhat arbitrarily) decided to use Python for this course, because it seems to be gaining popularity fast for astronomical data handling, and because some of you will have encountered it at the ATNF course. ... We've put Python (plus all relevant libraries) on the Stromlo Linux computers moron and maggot. ... Now log in to moron (or maggot). ...
