... By means of deep optical images obtained at the Special Astrophysical Observatory 6-m telescope it was discovered that some Seyfert galaxies that were earlier considered to be non-interacting objects displayed signatures of elongated tidal envelopes belonging to satellite debris. ... Our results suggest that statistic studies based on popular imaging surveys (for example SDSS) can lead to an underestimation of the fraction of minor mergers among galaxies with active nuclei (AGN). ...

... We can help students grasp the significance of Hubble's extremely keen eye, and learn a bit about angles and math in the process, with the following in-class activity. ... Looking through binoculars or telescopes allows us to magnify a small section of the sky. To measure sizes or distances in that small section, astronomers divide a degree into 60 smaller pieces called arcminutes, and further subdivide minutes into 60 smaller sections called arcseconds. ... 30 feet = . ... 36 seconds . ...

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

The first persistent Web agent that we have created on Actor Prolog is a program that collects information about research groups that develop Prolog and projects in the field of logic programming. The agent looks through a given list of Web sites and calculates some attributes of the sites: the date of recent modification, total size, the number of figures, the number of outside links, the number of error links, the number of given keywords, etc. ... http://www.cplire.ru/Lab144/space/prolog.html . ...

. While not entering text you use vi in command mode and enter editing commands consisting of one or more characters. The syntax of an editing command is: operator object . The operator is a character - such as d for delete - that describes the action to be carried out on the object; a word, sentence, paragraph or section. To return to command mode from insert mode press the ESC key. If you are already in command mode the terminal will beep at you (or make some similar sound).
