... Bad Astronomy . ... 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! ...

The Database of Close Binary Systems . ... Team . ... This web-based interactive database is being developed and maintained by a team at the Sternberg Astronomical Institute of the Moscow State University . The project is an on-line extension of our catalogue on "Highly Evolved Close Binary Stars" (volumes I, II) published by Gordon and Breach in 1996. As of September 2009, the database (both the software and the content) is in its development/testing phase. ...

... The event, a Type II supernova explosion, would have briefly dominated the night sky on Earth. ... Popularly known as the Veil Nebula, NGC 6960, NGC 6992, and NGC 6995 together constitute the corpse of a single supergiant star that perished in that supernova explosion. ... Such stars age about 1,000 times faster than does our Sun. ... Each nuclear-fusion stage releases energy and helps the star fight the ever-present pull of gravity. ...
