Every few months, one of a series of questions comes up on the USENET group sci.astro involving tides, or the rotation of the Moon, or the recession of the Moon from the Earth. ... Why the Moon's rotation period is the same as the length of time it takes to orbit the Earth (same as number 1, but phrased differently). ... But when this happens, the time it takes for the Earth to rotate once will be slowed to exactly the same time it takes for the Moon to go around the Earth once! ...

Nova 1998 2 in M31 this image of the second Nova in M31 in 1998, was made from 38 exposures of 45 seconds integration time. It was made at September 21, 22h 20m UT. Telescope was a CG11 at f/6.3, no filters were used. The long list of processing steps caused the artefacts at the overexposed center of the galaxy and in many of the brighter stars. During the exposures thin clouds covered the sky but the CCD cuts through them, allowing me to obtain this result. ...
