... 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. ...

In 2001, Westerbork observations of the disturbed galaxy named VV-29 (alias Arp-188, UGC-10214) showed that there is second smaller galaxy (named VV-29c) that appears behind the western side of the main body of the distorted galaxy. ... The galaxy was featured as the May 2, 2002 Astronomy Picture of the Day . ... When VV-29 had its 15 minutes of fame in May 2002, it appeared under the name "The Tadpole Galaxy," but based on the images above, we will always think of it as "The CHAINSAW"! ...

The File System . ... Files are identified to the system using a unique identifier called the file specification , which can include disk and directory names as well as node names for accessing files across the network. On VMS systems, file names are usually thought of as having three parts *1 : the filename , the file type , and the version number . ... The full file specification, with node name, device, directory, file name, file type, and version being specified is shown in Figure 3.1 . ...

The integers $ a_n=\sum_{k=0}^n{\binom nk}^2{\binom{n+k}k}^2, n=0,1,2,... $ appear as denominators of rational approximations to $\zeta(3)=\sum_{k=1}^\infty k^{-3}$ in Apery's proof of the irrationality of $\zeta(3)$. The sequence satisfies a polynomial recursion, namely, $ (n+1)^3a_{n+1}-(2n+1)(17n^2+17n+5)a_n+n^3a_{n-1}=0$, where $n=0,1,2,...$, and admits several curious congruence properties. ...
