. Top: A map of the hydrogen emission from DLA2222-0946. The mapped region, which covers only a portion of the galaxy, is about 5,000 parsecs (or 16,300 light-years) across. The position of the background quasar is marked by a "Q". Bottom: The corresponding map of the movement of the gas in the galaxy. Red means moving away from us; blue is moving towards us. R.

... 2003 June 18 . Clouds and the Moon Move to Block the Sun . ... Explanation: High above a small church near Vienna, Austria , clouds and the Moon vied for position in front of the Sun. Such was the case on the ground late last month during a partial eclipse of the Sun visible throughout Europe and Asia . Nearing the farthest part of its orbit around the Earth , the Moon's angular size was too small to block the entire Sun, a situation that would have resulted in a total solar eclipse . ...

This section of AMPLE makes it possible to find all those numbered minor planets which can be seen at the given moment in certain part of the sky (e.g. covered by photographic plate or by CCD frame), to calculate their coordinates and to display their mutual positions and diurnal motions. ... If the center of the mapped sky region is situated not far from the opposition point and its angular dimensions are not too great, positions of minor planets are found with account for perturbations. ...

Underdetermined sets is a new type of data structures (terms) developed in Actor Prolog . ... The point is that an underdetermined set can include some indefinite rest (a tail) like a list in usual Prolog . At the same time, the order of elements of an underdetermined set can be arbitrary one and it does not affect results of unification of underdetermined sets. Moreover, Actor Prolog guarantees that a rest of an underdetermined set never contains elements that are explicitly given in the set. ...
