Why Stars Twinkle . ... Credit Copyright: Applied Optics Group ( Imperial College ), Herschel 4.2-m Telescope Explanation: This is what a star really looks like from the surface of the Earth. To the best the human eye can see, stars are so far away they appear the same as would infinitesimal points of light. ... Because the atmosphere is always windy and changing, the number and position of images is always changing, with the result that stars appear to twinkle . ... NASA Official: Jay Norris. ...

... Bad Astronomy . ... Bitesize Astronomy . ... Last week's Snack talked about how black holes can affect the environment around them in such a way as to be very bright . ... It's a common misconception that black holes always have matter swirling into them. ... As this matter gets closer and closer to the black hole it piles up and a large, fairly flat disk forms. This is called the accretion disk , because matter from this disk accretes (that is, falls in) on the black hole. ... 2008 Phil Plait. ...

September, 2008 The root of the problem is that people are morons, more particularly, developers are morons, very particularly, xterm developers are morons. ... In fairness, it's not really the xterm that's incompatible, it's the xterm descriptions that ship with modern operating systems that are incompatible with older xterms. ... The developers had to know that people would actually USE the cool new features they put into xterms. ... A modern xterm! ... Line 'em up along with the xterm developers. ...

We present new images of the reflection nebula surrounding the R Coronae Borealis Star, UW Centauri. ... Instead, the morphology of the nebula appears to change as different parts are illuminated by light from the central star that is modulated by shifting thick dust clouds near its surface. ... In this way, the central star acts like a lighthouse shining through holes in the dust clouds and lighting up different portions of the nebula. ... ADS Citation Query . citations = 21 . ...

... From the user's point of view, the widget consists of a text entry box and a pull down menu from which the user can select one of a set of predefined entries. ... Now, if you want to set the string in the entry section of the combo box, this is done by manipulating the entry widget directly: gtk_entry_set_text (GTK_ENTRY (GTK_COMBO (combo)->entry), "My String." To set the values in the popdown list, one uses the function: void gtk_combo_set_popdown_strings( GtkCombo *combo, GList *strings ); . ...

... Forum: The Linux Kernel Hackers' Guide . Re : Changing the scheduler from round robin to shortest job first for kernel 2.0 and up . ... It get ur idea that you wanna better understanding of the OS. But I really wonder whether the system will behave sane if you do the changes. You have not told abt ur M/c.

spaceweb@oulu.fi - last update: 20 November 1998, 1440 UT (RR) . The 'space weather' have been coined to point out that many of the phenomena studied in space physics have also important practical consequences (e.g., Davenport, 1996). In addition to the geomagnetic activity , also changes in the atmosphere , or even comets and man-made debris in space, can be of importance. ... The other serious consequence of bad space weather is the possibility of damage to Earth orbiting satellites. ...
