I'd guess that on Friday, people are reading up on reviews and/or discussions in either Movies or HT Software, to decide what to watch over the weekend, thereby giving a "bump" in traffic which otherwise would taper off precisely because of the weekend.
The rings, upon closer inspection, bear striking similarities to the grooves on vinyl. By using laser interferometry, the perturbations in the rings, can be decoded much in the same way a stylus extracts the sounds from the grooves in a record. Then its a simple matter to amplify those. Attempts were made to use RIAA deemphasis but it seems a different encoding scheme is at work here.
Funny you should mention that, because "Saturn" is my favorite movement in The Planets. On the basis of sheer performance attributes, I prefer the late Sir Adrian Boult's interpretation, with the New Philharmonia Orchestra on Angel/EMI. William Steinberg's with the Boston Symphony Orchestra (on Deutsche-Grammophon) is nice, too (and with better sonics, those multimiking and spotlight miking detract; I'm a purist who prefers the old Mercury Living Presence approach of three microphones, also used by Telarc)).
Jack, if you like Adrian Boult's performance of the "Saturn" movement, may I recommend checking out the "Planets" symphony as conducted by the legendary Leonard Bernstein and the Boston Symphony Orchestra or even the performance conducted by Sir Charles Mackerras and the Liverpool Orchestra (I forget their exact name at the current moment). Both of these are excellent adaptations of the Holst symphony and make for great musical accompaniments in viewing the Cassini photos of Saturn.
