... 2011 September 11 . On the Origin of Gold . Image Credit: Dana Berry, NASA . ... The relative average abundance in our Solar System appears higher than can be made in the early universe , in stars , and even in typical supernova explosions .

It's a common misconception that black holes always have matter swirling into them. ... As this matter gets closer and closer to the black hole it piles up and a large, fairly flat disk forms. This is called the accretion disk , because matter from this disk accretes (that is, falls in) on the black hole. ... 2008 Phil Plait. ...

... The default run_state of all incoming runs is now OPEN . The support astronomer has to inform the operations support scientists if the run_state for a run has to be changed (e.g. after consulting the Database Consistency Check Page which is updated hourly from 9:30 to 17:30, Garching time) . The default run_state of all SM runs for next period is NEXT . By default, all NEXT runs will be set to OPEN at the start of the new period. ... COMPLETED or TERMINATED . ... COMPLETED . ...

... Professor Mark Bailey completed work with the former PDRA Vacheslav Emel'yanenko on the capture of Halley-type comets from the long-period cometary flux. He also completed a paper with Ph.D. student Scott Manley on collision probabilities between small solar system bodies, and together with PDRA David Asher and visiting research fellow Vacheslav Emel'yanenko provided the explanation for the unexpected outburst of Leonid fireballs on the morning of 1998 November 17. ...

In 2001, Westerbork observations of the disturbed galaxy named VV-29 (alias Arp-188, UGC-10214) showed that there is second smaller galaxy (named VV-29c) that appears behind the western side of the main body of the distorted galaxy. ... The galaxy was featured as the May 2, 2002 Astronomy Picture of the Day . ... When VV-29 had its 15 minutes of fame in May 2002, it appeared under the name "The Tadpole Galaxy," but based on the images above, we will always think of it as "The CHAINSAW"! ...

The Sun's corona . ... For instance, short "plumes" rising from the polar regions of the Sun look very much like field lines coming out of the end of a bar magnet, and they therefore suggest that the Sun, in addition to the intense fields of sunspots, also has a global magnetic field like the Earth's.
