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). ...

The original files with the data were in different formats. ... Such files were named "standard data files" and linked to the database. They can be easily transformed to any desirable format by a code. Here we present two simple computer programs of this kind. ... When running the code, you can specify columns in the output file: wavelength, energy (eV) or wavenumber (cm -1 ) as the first column, and complex refractive index or dielectric function as the second and third columns. ...

A very important stage in a story of formation of any new science is the shift from discussion of situation which are possible but do not occur in practice due to some reason to recognition of real phenomena of interest. ... We suggest to consider computer viruses as this new specific form of life which is coming in the contact with our form of life. ... Computer life has been created by human being, the role of independent evolution of computer viruses seems to be still negligible. ...

... This is possible at modest cost due to the low moments of inertia of the telescope and enclosure. ... This same performance will be achieved in higher winds when the telescope enclosure is facing away from the wind, or by using wind screens. ... The telescope system (MILT) will be remotely operable with an on-site operator's assistance by an astronomer located at one of the ARC member institutions. ... Mean Wind Speed . ...
