Not all meteors are sporadic events, the regular meteor showers occur when the Earth bulldozes through a great swarm of meteoroids drifting in orbit round the Sun. ... They are at their best in the pre-dawn hours, as the face of the Earth turning towards the Sun catches more meteors as the Earth moves through space. ...

. Lines are sorted character by character, starting at the first character in the line. You can also sort the contents of a file on a specific part of each line. Each line of text is a series of fields - words and other characters - separated from each other by a delimiter character - the spaces between the words. Changing the field delimiter . Defining the sort field . Sorting on several fields . Sorting on a specific part of a field .

This form calculates which transits of the 1039 known transiting exoplanets are observable from a given location at a given time. Specify a time window, an observing location (either an observatory from the list or choose "Enter latitude/longitude" at the end of the list), and optionally any filters (e.g. minimum transit depth or elevation). The output includes transit time and elevation, and links to further information about each object, including finding charts and airmass plots. ...

Figure 23: Binary pulsar fractions among the total number of pulsars   as a function of the mean kick velocity for a maxwellian distribution   (left-hand panel) and that fitting Lyne and Lorimer's data (right-hand panel). ... Therefore, the observed diversity and number of binary pulsars, while requiring a small kick velocity ( 100-150 km s ) to be present, are, at the same time, in strong contradiction with the presently derived high mean transverse velocities of pulsars. ...

... Under certain conditions, like those in the nucleus of a QSO, all atoms can be made to emit light at particular wavelengths. ... If that source is approaching the observer, the wave is squashed up onto itself making the wavelength shorter. ... This is redshift. ... You can see how the section of the QSO spectrum which we observe changes with redshift. ... We then see how far we had to slide the observed spectrum along the scale to make it match and that is the objects redshift. ... The 2QZ team . ...

In Actor Prolog a resident is a special mechanism that helps processes to inspect state of other processes. A resident observes the state of a specified (target) process and if the state of the process changes (for instance, after message handling) it proves a specified predicate of the process. ... Work of the resident. ... Any change of the list of target processes or arguments of resident function results in activation of the resident and repeated collection of information in the target worlds. ...
