. The sharply-defined crater just above the center of this Cassini image shows layers of alternating bright and dark material. A thin dark layer on the crater wall appears to define the base of an ejecta blanket. Cassini was 8,314 miles (13,377 km) from Phoebe when this image was taken. NASA / JPL / CICLOPS

... In some of the shots the Sun creeps into view - particularaly during the sunset sequence. ... The dust halo takes up a lot of rendering time so it is usually deactivated - it would be nice to have it enabled during the final descent and impact but the number of light sources required would make this unfeasably slow. ...

New England observer Lew Gramer, fresh back from his mid-November fish observing and meteor-catching expedition in South Florida, reports that December also promises to be a great month for celestial sky-sparks!" ... Other showers adding to the mix this month include several very minor showers, such as the Chi Orionids (3 Dec), Monocerotids (9 Dec) and Sigma Hydrids (12 Dec), which usually contribute no more than 2 or 3 meteors per hour during even post-midnight observing this month. ...

... It turns out one possibility is a form of matter/energy invented by Einstein in the 1920s to make sure his equations of General Relativity did not predict the Expansion of the Universe. Although Einstein was willing to predict several things with his equations of General Relativity, he obviously thought an expanding Universe was too much, and so he invented the Cosmological Constant, which repels itself, and was meant to balance the force of gravity, and make the Universe static. ...

Spectral jumps were seen in data taken back in 18mar08 . That data had the rms fixed at 15 and changed pshift as well as fixing pshift and changing the rms. ... Take 6 sets of data. At each set, take data with fftlens = 8192,4096,2048,1024, and 512. fftlengths with even, odd number of butterfly stages will have rms voltage levels that differ by sqrt(2) (since the butterfly down shift changes voltage by factor of 2 and it takes 2 butterfly stages to increase the rms by a factor of 2). ... rms . ...
