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 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. ...
