This animation shows a galaxy cluster with two mass concentrations (the pink shading indicates the projected mass density) lensing a background field of faint blue galaxies. ... Inside the Einstein ring radius one has radial arcs, and right in the center of the cluster there are demagnified images. The highest magnifications occur at the Einstein ring radius, giving the large tangential arcs. ... Abell 2218 and CL2244-02 are clusters with tangential arcs. ... Tutorial : Part 1 | Part 2 | ...

New England observer Lew Gramer, fresh back from his mid-November fish observing and meteor-catching expedition in South Florida, reports that December also promises to be a great month for celestial sky-sparks!" ... Other showers adding to the mix this month include several very minor showers, such as the Chi Orionids (3 Dec), Monocerotids (9 Dec) and Sigma Hydrids (12 Dec), which usually contribute no more than 2 or 3 meteors per hour during even post-midnight observing this month. ...

Only one other comet, Comet Halley, was seen so far from the Sun, giving scientists an opportunity to watch it as it slowly warmed up and sprouted a tail. ... Comets are the Rip Van Winkles of the solar system -- mini-worlds that have changed little during their 4.5-billion-year nap far from the Sun. ... Observing Comets . ...

Stellar population of the interacting galaxies M51. ... Stellar photometry of about one million stars in the system of the interacting galaxies M51 has been carried out on the basis of the ACS images of the Hubble Space telescope. ... A comparison of the stellar distribution in the main galaxy NGC 5194 with the empirical model of the distribution of stars showed their similarity, in spite of interaction in the system. ...

... We address a question if globular clusters (GC) in a protogalaxy could for some time evolve chemically as isolated systems, enriching themselves with heavy elements produced in first supernova events that follow initial star formation. We determine both the critical mass of a protoglobular cluster that is needed to retain the ejecta of the very first supernova, and the critical energy (i.e., number of supernovae) that is needed to expel the residual gas from a cluster of a given mass. ...

... This damage causes low energy redistribution changes Enhanced dark current at raised temperatures has been seen in CCDs illuminated with a focussed beam at the Panter facility ( EPIC EOBB and Swift XRT) Have so far not been able to detect the low energy redistribution in these devices Need to replicate conditions in orbit ­ possibly by keeping device cold over an extended period ...

A STUDY OF THE FRAGMENT DISPERSAL AND TRAJECTORY OF THE SAYH AL UHAYMIR 001 METEORITE SHOWER. ... We obtained hundreds of GPS find locations, analyzed the fragment distribution, and developed a model of the meteorite's trajectory. ... More than 2670 samples weighing more than 450 kg have been collected. ... Increasing fragment mass along track indicated a flight direction of 233o. The fragments' mass distribution was used to model the meteorite trajectory. ...

... Positive iterative deconvolution is an algorithm that applies non-linear constraints, conserves energy, and delivers stable results at high noise-levels. This is also true for Richardson-Lucy like algorithms which follow a statistical approach to the deconvolution problem. ...

This example shows a difference between CSS's table model for HTML and for other document formats. The first, HTML, example is defined by HTML to be illegal, as it would lead to overlapping cells if HTML's rules for layout are followed. ... The diagram depicts how the two examples, the HTML one and the almost identical non-HTML one, might be rendered. ... The rendering of the non-HTML example is on the right, it follows the CSS rules and thus has no overlapping cells. ...

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. ...
