... 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. ...

Koutchmy ( IAP , CNRS ) Explanation: Sometimes, a total eclipse is a good time to eye the Sun. Taking advantage of an unusual juxtaposition of Earth, Moon and Sun , the featured image depicts the total solar eclipse that occurred last month as it appeared -- nearly simultaneously -- from both Earth and space. ...

... On the morning of Thursday, 26 February, amid the Gal pagos Islands, the Sun will fade from view. Not the culmination of ancient prophecy, but none less mystical, Earth's small Moon will be executing a slow slide past the enormous Sun. ... And anyone living in southern North America, Central America, northern South America, or on islands and cruise ships in the Caribbean Sea will, weather permitting, have the opportunity to experience the wonder of a solar eclipse. ...

... 2000 January 26 . A Lunar Eclipse Over Time . ... Explanation: During last week's lunar eclipse , our Moon appeared to disappear. As the Earth moved between the Moon and the Sun, the Earth's shadow fell on the moon, making it quite dark . ... As the Earth's shadow engulfed the Moon , the Moon streak became less and less bright, practically disappearing during totality . ... Later, clouds obscured the re-appearing Moon. ...

... 4.4 Imbedding HTML in a Document . In the following discussion of SPECIAL processing
, I will assume that rtftohtml has not been customized. If it has, the text styles used to create special effects may be different. ... Normally, if your RTF document contained the text "<cite>hello</cite>", the translator would output this as: "&lt;cite&gt;hello&lt;/cite&gt;". ... If, however, you want the <cite></cite> to be interpreted as HTML markup, you must format the tags using Hidden and Shadow. ...

The Sun's corona . ... For instance, short "plumes" rising from the polar regions of the Sun look very much like field lines coming out of the end of a bar magnet, and they therefore suggest that the Sun, in addition to the intense fields of sunspots, also has a global magnetic field like the Earth's. Arches above the . Sun's surface . ... It is brightest near sunspots, whose arched field lines apparently hamper the outflow of solar wind which carries away energy and helps cool the corona. ...

... Figure 1: Diagram of rgsproc sub-tasks and data-flow. ... 1:events : preliminary tasks, source-independent calibrations . ... The first stage of processing performs basic calibrations on the events in separate, CCD-specific intermediate event lists and then gathers them together in the combined event list . ... Name collisions among tables copied in from the intermediate event lists are avoided by placing the corresponding CCD number at the eighth character of the extension name. ... int32 . ...
