Hubble Predicts the Future of Omega Centauri – Using four years of data from the Hubble Space Telescope’s Advanced Camera for Surveys, astronomers have made the most accurate measurements of the movement of stars in the globular cluster Omega Centauri, and now can predict their movements for the next 10,000 years. This “beehive” of stars is tightly crammed together, so resolving the individual stars was a job that perhaps only Hubble could do. –Nancy Atkinson / Universe Today

ISS Fires Its Rockets to Avoid Space Debris Collision – The International Space Station (ISS) fired its rockets for three minutes Tuesday to change its position in order to avoid a possible collision with a piece of orbiting junk, officials said.The Itar-Tass agency cited Russian space centre officials outside Moscow as saying that the chances of a collision were minimal – only one-thousandth of a per cent. –Daily Galaxy

Countdown to Comet Flyby Down to Nine Days – NASA’s EPOXI mission continues to close in on its target, comet Hartley 2, at a rate of 12.5 kilometers (7.8 miles) per second. On Nov. 4 at about 10:01 a.m. EDT (7:01 a.m. PDT) the spacecraft will make its closest approach to the comet at a distance of about 700 kilometers (434 miles). It will be the fifth time that a comet has been imaged close-up and the first time in history that two comets have been imaged with the same instruments and same spatial resolution. –NASA/JPL

3C186: Precocious Galaxy Cluster Identified by Chandra – NASA’s Chandra X-ray Observatory has observed an unusual galaxy cluster that contains a bright core of relatively cool gas surrounding a quasar called 3C 186. This is the most distant such object yet observed, and could provide insight into the triggering of quasars and the growth of galaxy clusters. –NASA/Chandra
