This frame from the simulation shows the X-rays produced by a black hole (white) and its effects on nearby gas (blue). This scene occurs 400 million years after the universe formed, (c) KIPAC/SLAC/M. Alvarez, T. Abel and J. WiseFirst black holes kept to a strict diet

A new supercomputer simulation designed to track the fate of the universe's first black holes finds that, counter to expectations, they couldn't efficiently gorge themselves on nearby... — full story

Astronomers discover stars in early galaxies had a need for speed

— 7 Aug 2009 12:16 | Astronomy

A team of astronomers has measured the motions of stars in a very distant galaxy for the first time and discovered they are whizzing around at astonishingly high speeds - about one... — full story

D'Onghia and her colleagues simulated encounters between galaxies to determine how dwarf galaxies lose much of their stars and gas. Top row: Interaction between a dwarf galaxy orbiting around a larger galaxy with 100 times its mass. Only the stars are plotted. The upper left panel illustrates the initial set up where the two dwarfs approach one another. The upper middle panel gives the state of the system after 2 billion years, and the upper right panel shows the appearance of the galaxies after 7 billion years. Bottom row: Shown is the orbit of the same small galaxy (in white) around the Milky Way today (in yellow), which has 10,000 times its mass, (c) Elena D'Onghia (CfA)Cosmic dance helps galaxies lose weight

The 'eye' at the centre of the galaxy is actually a monstrous black hole surrounded by a ring of stars, (c) NASA/JPL-CaltechSpitzer images out-of-this-world galaxy

— 23 Jul 2009 17:49 | Astronomy

NASA's Spitzer Space Telescope has imaged a wild creature of the dark - a coiled galaxy with an eye-like object at its centre. The galaxy, called NGC 1097, is located 50 million light-years... — full story

Three-colour composite mosaic image of the Eagle Nebula (Messier 16), based on images obtained with the Wide-Field Imager camera on the MPG/ESO 2.2-metre telescope at the La Silla Observatory. At the centre, the so-called 'Pillars of Creation' can be seen. This wide-field infrared image shows not only the central pillars, but also several others in the same star-forming region, as well as a huge number of stars in front of, in, or behind the Eagle Nebula, (c) ESOAn eagle of cosmic proportions

Research by a Michigan State University scientist sheds new light on how stars and galaxies were formed back in the early days of the universe - some 13 billion years ago... — full story

Living fossils hold record of 'supermassive' kick

— 10 Jul 2009 15:28 | Astronomy

The tight cluster of stars surrounding a supermassive black hole after it has been violently kicked out of a galaxy represents a new kind of astronomical object and a fossil record... — full story

Three-colour composite image of the Omega Nebula (Messier 17), based on images obtained with the EMMI instrument on the ESO 3.58-metre New Technology Telescope at the La Silla Observatory. North is down and East is to the right in the image. It spans an angle equal to about one third the diameter of the Full Moon, corresponding to about 15 light-years at the distance of the Omega Nebula, (c) ESONew portrait of Omega Nebula's glistening water-colours
