... An OBJECT column gives the name of the object observed (usually a star name). ... In critical cases, it is common practice to measure sky on two or more positions around a target object, and these positions must be identified. ... A general treatment of this problem requires a column called OBJECT, bearing the usual name of the object (as in the star tables); a column labelled STARSKY, to distinguish between star+sky, star alone, or sky alone; and additional columns to identify the sky position. ...

An extra leap second has to be inserted at the end of 2008, so this is how you should count down on New Year's Eve to celebrate the start of the International Year of Astronomy according to Irish astronomers. The extra second is needed to bring the uniform measure of time used by physicists using atomic clocks back into nearly exact agreement with time as measured by the rotation of the Earth. ... There will be national and international events organized throughout the year to mark the occasion. ...
