 | The European Space Agency (ESA) signalled the start of a busy period for the planet Mercury, when it signed the contract for industrial development to start for the BepiColombo mission today (18th January 2008) at Astrium in Friedrichshafen, Germany. UK scientists and industry have key roles in BepiColombo, including construction of spacecraft subsystems and science instrument design. ...> Full Article |
 | On 12 January, China scientific expedition to the Antarctica succeeded for the second time in climbing up to Dome A, the highest Antarctic icecap peak. A similar feat was made by Chinese scientists about three years ago in January 2005, leaving first human footprints there. However, this time is different, because it is the maiden trip for Chinese astronomers, Prof. ZHOU Xu with the National Astronomic Observatories at CAS (NAOC) and Prof. ZHU Zhengxi from the CAS Purple Mountain Observatory (PMO), marking a new milestone for the cosmic exploration based on the apex of the Antarctic icecap. ...> Full Article |
 | NASA's Spitzer Space Telescope has detected plump black holes where least expected -- skinny galaxies. Like people, galaxies come in different shapes and sizes. There are thin spirals both with and without central bulges of stars, and more rotund ellipticals that are themselves like giant bulges. Scientists have long held that all galaxies except the slender, bulgeless spirals harbor supermassive black holes at their cores. Furthermore, bulges were thought to be required for black holes to grow. ...> Full Article |
 | When Mariner 10 flew past Mercury three times in 1974 and 1975, the same hemisphere was in sunlight during each encounter. As a consequence, Mariner 10 was able to image less than half the planet. Planetary scientists have wondered for more than 30 years about what spacecraft images might reveal about the hemisphere of Mercury that Mariner 10 never viewed. ...> Full Article |
 | Until now, Mars has generally been regarded as a desert world, where a visiting astronaut would be surprised to see clouds scudding across the orange sky. However, new results show that the arid planet possesses high-level clouds that are sufficiently dense to cast a shadow on the surface. ...> Full Article |
 | Astronomers have produced a scientific gold mine of detailed, high-quality images of nearby galaxies that is yielding important new insights into many aspects of galaxies, including their complex structures, how they form stars, the motions of gas in the galaxies, the relationship of "normal" matter to unseen "dark matter," and many others. ...> Full Article |

 | University of Arizona astronomers Glenn Schneider, Michael Meyer and J. Serena Kim are among scientists who combined images from the UA-led infrared camera on NASA's Hubble Space Telescope with images from NASA's Spitzer Space Telescope into a spectacular image of a star's dust disk dubbed "The Moth." ...> Full Article |
 | The appearance of a very special solar spot on the sun surface a few days ago, signalled to scientists around the world that a new solar cycle had begun. This solar spot also produced two solar blasts. ...> Full Article |
Looking up at the night sky you could be forgiven for believing that the sedate progress of the stars across the firmament belies the serene nature of galaxies. But a closer look at our celestial neighbours reveals that the reality is very different.

 | Excitement is rising as ESA is in the final stages of preparation for the first collaborative space mission with the Indian Space Research Organisation (ISRO). Chandrayaan-1 will study the Moon in great detail and be the first Indian scientific mission leaving the Earth's vicinity. ...> Full Article |
 | Hundreds of millions - or even billions - of years after planets would have initially formed around two unusual stars, a second wave of planetesimal and planet formation appears to be taking place, UCLA astronomers and colleagues believe. ...> Full Article |

A team of scientists have announced the beginning of a new multi-year survey, the third generation of the Sloan Digital Sky Survey, which will use a suite of new instruments to investigate a wide range of scientific topics. Building on eight years of extraordinary discoveries by the Sloan Digital Sky Survey (SDSS and SDSS-II), the new program of four coordinated surveys will revolutionize the study of the distant universe, the Milky Way galaxy, and giant planets orbiting other stars, and the largest of these surveys will use a novel and powerful technique to study dark energy, one of the biggest mysteries in contemporary science.

 | The shape of the mysterious cloud of antimatter in the central regions of the Milky Way has been revealed by ESA's orbiting gamma-ray observatory Integral. The unexpectedly lopsided shape is a new clue to the origin of the antimatter. ...> Full Article |
 | Having the sharpest pictures always is a big advantage, and a sophisticated radio-astronomy technique using continent-wide and even intercontinental arrays of telescopes is yielding extremely valuable scientific results in a wide range of specialties. That's the message delivered to the American Astronomical Society's meeting in Austin, Texas, by Mark Reid of the Harvard-Smithsonian Center for Astrophysics, a leading researcher in the field of ultra-precise astronomical position measurements. ...> Full Article |
 | NASA's Hubble Space Telescope has revealed a never-before-seen optical alignment in space: a pair of glowing rings, one nestled inside the other like a bull's-eye pattern. The double-ring pattern is caused by the complex bending of light from two distant galaxies strung directly behind a foreground massive galaxy, like three beads on a string. ...> Full Article |
A new study using results from NASA's Chandra X-ray Observatory provides one of the best pieces of evidence yet that many supermassive black holes are spinning extremely rapidly, according to a research team led by a Penn State astronomer. The whirling of these giant black holes drives powerful jets that pump huge amounts of energy into their environment and affects the growth of galaxies.

 | For the first time astronomers are able to see indirect evidence of dark matter and how this invisible force impacts on the crowded and violent lives of galaxies. University of British Columbia researcher Catherine Heymans has produced the highest resolution map of dark matter ever captured before. ...> Full Article |
It turns out that our math teachers were right: being able to solve problems without a calculator does come in handy in the "real" world. Two theoretical physicists at Rensselaer Polytechnic Institute have used what they call "pen-and-paper math" to describe the motion of interstellar shock waves - violent events associated with the birth of stars and planets.

 | Our planet is changing before our eyes, and as a result, many species are living on the edge. Yet Earth has been on the edge of habitability from the beginning. New work by astronomers at the Harvard-Smithsonian Center for Astrophysics shows that if Earth had been slightly smaller and less massive, it would not have plate tectonics - the forces that move continents and build mountains. And without plate tectonics, life might never have gained a foothold on our world. ...> Full Article |

A team of Sloan Digital Sky Survey (SDSS-II) scientists, led by Princeton University's Reinabelle Reyes and including astronomers at Penn State, has identified a large number of "hidden quasars" -- supermassive black holes in the centers of galaxies that are shrouded in light-absorbing dust and gas. According to Donald Schneider, coauthor of the paper and professor of astronomy at Penn State, "If one examines a photograph of one of the hidden quasars we discovered, it appears to be just an ordinary galaxy, although quasars are typically are 10 to 100 times more luminous than the Milky Way Galaxy." Schneider is the chair of the SDSS-II science group that studies quasars, which are powered by glowing, super-heated gas as it swirls into black holes a billion times more massive than the sun.
