... The derived position here agrees with the position from recent ATCA observations, RA=15h 01m 34.74s, Dec=39 18 39.2" (Tasker, private communication) which found the source unresolved. Because of the relatively large position offset, the reality of the fainter component 0.12" to the west is somewhat in doubt. However, the ATCA centroid position is offset by 0.3" to the south-east of the VLBA position, suggesting that the faint component may be part of more extended structure. ...

... Tonight's Sky . ... т??Standard candleт?? supernova extraordinarily magnified by gravitational lensing . ... A team of researchers at the Kavli Institute for the Physics and Mathematics of the Universe (IPMU) led by Robert Quimby has identified what may prove to be the first ever type Ia supernova (SNIa) magnified by a strong gravitational lens. In this work, the standard candle property of type Ia supernovae is used to directly measure the magnification due to gravitational lensing. ...

... 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! ...
