Anemic Galaxy NGC 4921 at the Edge . ... Credit Copyright: NASA , ESA , K. Cook ( LLNL ) Explanation: How far away is spiral galaxy NGC 4921? ... Toward this goal, this image was taken by the Hubble Space Telescope in order to help identify key stellar distance markers know as Cepheid variable stars. Since NGC 4921 is a member of the Coma Cluster of Galaxies , refining its distance would also allow a better distance determination to one of the largest nearby clusters in the local universe. ...

... The air just sit there and doesn't get stirred. ... Normally, the air is hottest near the ground and gets cooler as you go up. ... If it weren't for the temperature profile, convection wouldn't occur: Because the temperature decreases with altitude, cold air sits on top of hot air, allowing convection. ... The air above the ground is hot, the air above the water is cold. ... The land cools down faster than the sea, so the air above the ground is colder than the air above the water. ...

Pulkovo NEO Page . ... NEA Accuracy Estimation . ... The estimation of accuracy of the current CCD observations of asteroids and comets is constantly performed at Pulkovo Observatory. ... The (O-C) values, so called "Observed" minus "Calculated" positions, characterize numerically the observations of any observatory, both professional and amateur, during a short period (one or several close nights). ... So the (O-C) values for these objects nearly entirely define the errors of observations. ...

The annual Quandrantid meteor shower makes its return in 2007 from 1st - 6th January. ... Viewing conditions, however, for the shower this time around are somewhat unfavourable as the peak of activity occurs near full Moon thus making it difficult to observe the fainter meteors. ... Peter Jenniskens of the NASA Ames Research Center in California, USA has pointed out that the source for the Quadrantids might be a recently discovered asteroid, or inert comet, 2003 EH1. ...
