1. Phil Plait's Bad Astronomy: Bitesize Astronomy
... 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. ...

7. The Sun's Corona
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. ...

17. How the Data is Processed
Next: Running REDUCE/CCD Up: Processing the Data Previous: Processing the Data . Before any processing on the input frame is done, the REDUCE/CCD command will first collect all resources needed for the calibration of the science frame(s). These include the master calibration frames, the overscan offset, and scaling parameters. So, at this point no operations are done yet. ... As an example, suppose the science frame is supposed to be corrected for dark current and to be flat fielded. ...
