In practice this is of limited value with webcams because the image moves around the frame enough to average out the effect of ‘dust bunnies’ on your chip (Figs. 4.9, 4.10, 4.11, 4.12, 4.13 and 4.14). 64 4 Photographing the Moon and Planets Fig. 4.8 Use this menu to create a dark frame and a flat frame. You select an avi file in the usual way and press ‘Create darkframe.’ Registax will then process the movie clip and stack the frames to make a dark frame. Having saved it as a bmp file, you.
Abundance, etc. Thus if you do the math, you find out that hydrogen is over a trillion times as abundant as uranium (Image courtesy of http://en.wikipedia. org/wiki/File:SolarSystemAbundances.png, licensed under the Creative Commons AttributionShare Alike 3.0 Unported) than a white dwarf. The outer material cannot collapse into the ultra-dense neutron star, and it appears that the shock wave of the collapse rebounds, and causes the outer material to be expelled into a large cloud. The Crab.
Currently pointing towards the Sun we can see, not by the direction of the line from Earth to the Moon. Thus the time to orbit is not quite the same as a ‘lunar month,’ the time taken for a given phase to reappear. It is well known that the Moon presents pretty well the same face to us all the time because its rotation period is the same as its orbital period. 92 6 Earth’s Nearest Neighbor: The Moon Fig. 6.6 Moon, April 5, 2009, 23:23 UT, plus the image from Fig. 6.4.

Much of the literature on the subject is authored by Melosh, Ivanov or both, but independent support for this acoustic fluidization hypothesis comes from Osinski and Pierazzo [64]. These authors argue that although the idea of acoustic fluidization is controversial, Melosh and Ivanov need only one set of material properties to explain the known crater morphology. The theory would be less likely to be valid if the rock properties had to change for every impact analyzed. That would look like making.

You can just about make out the outlines of Germany, Austria, Switzerland and Italy to the south and the Czech Republic to the north (Image by the author) 122 6 Earth’s Nearest Neighbor: The Moon Fig. 6.45 Something unexpected.
