Lunar Libration . Articles | ... Actually, a slight rocking motion, called libration,* makes about 59% of the Moon's surface visible from our planet Earth -- though only 50% at any one time. ... Add to that, the approximate 1.5 degree tilt of the Moon's equator to the ecliptic, and you have the inclination of the Moon's equator to the plane of its orbit around Earth at some 6.5 degrees (5 + 1.5 = 6.5). ...

... We have performed a series of tests to find an optimal data distribution in the Cray T3D memory, and to identify a strategy for the Dynamic Load Balance (DLB). ... N-body simulations are one of the most important tools in contemporary theoretical cosmology, however the number of particles required to reach a significant mass resolution is more larger than those allowed even by present-day state-of-the-art massively parallel (Gouhing 1995; Romeel 1997 & Salmon 1997) supercomputers (hereafter MPP). ...

. This image shows one of the clamps used to hold counterweights. It is held in its approximate location on the back of the PSS. In the final implementation there would be two of these clamps side by side, separated by less than a foot. The clamps would be mounted on an adapter plate to facilitate mounting the pair of clamps on on the curved outer surface of the PSS. The entire weight system will not interfere with the doghouse door. long@apo.nmsu.edu

As the Universe expands, gravity pulls on the Universe, and slows the expansion down over time. As we look to great distances, we are looking back in time. If we can measure how fast the Universe is expanding in the past, and compare it to how fast it is expanding now, we can see the total gravitational effect of all matter in the Universe. Here we plot the distance between two galaxies as a function of time. ... Universes with lots of material . ...
