This area deals with the fundamental laws and building blocks of nature and how they interact, the properties and the behavior of matter, and research into space and time and their structures.
innovations-report provides in-depth reports and articles on subjects such as astrophysics, laser technologies, nuclear, quantum, particle and solid-state physics, nanotechnologies, planetary research and findings (Mars, Venus) and developments related to the Hubble Telescope.
A new survey made with the Anglo-Australian Telescope (AAT) has revealed dozens of previously unsuspected miniature galaxies in the nearby Fornax galaxy cluster. They belong to a class of galaxies dubbed “ultra-compact dwarfs” (UCDs), which was unknown before the same team of astronomers discovered 6 of them in the Fornax cluster in 2000. Now they say the UCDs outnumber the “conventional” elliptical and spiral galaxies in the central region of the Fornax cluster and they have found some in the Virgo
An international group of astronomers led by Dr Jean-Philippe Beaulieu (Institut dAstrophysique de Paris) and Dr Martin Dominik (University of St Andrews) are about to continue their hunt for extrasolar planets with an enhanced world-wide telescope network in May this year. They are hoping to secure the firm evidence for the existence of Earth-mass planets orbiting stars other than the Sun, which has so far eluded astronomers. Dr Dominik will describe the project, known as PLANET (Probing Lensi
Genetic mutations – sudden, random and usually harmful changes to the structure of a gene – are only one factor that determines the ultimate fate of a cell. Chicago scientists have discovered that a non-genetic molecular process also can play a role, and that experimenters can influence this process in bacteria, they report in the April 1 issue of the journal Nature.
The research team, led by Philippe Cluzel, Assistant Professor in Physics at the University of Chicago, arrived at its finding
Optimizing space missions
Titan, the largest moon of Saturn was discovered by Dutch astronomer Christian Huygens in 1655 and certainly deserves its name. With a diameter of no less than 5,150 km, it is larger than Mercury and twice as large as Pluto. It is unique in having a hazy atmosphere of nitrogen, methane and oily hydrocarbons. Although it was explored in some detail by the NASA Voyager missions, many aspects of the atmosphere and surface still remain unknown. Thus, the existenc
When the European Huygens probe on the Cassini space mission parachutes down through the opaque smoggy atmosphere of Saturns moon Titan early next year, it may find itself splashing into a sea of liquid hydrocarbons. In what is probably the first piece of “extraterrestrial oceanography” ever carried out, Dr Nadeem Ghafoor of Surrey Satellite Technology and Professor John Zarnecki of the Open University, with Drs Meric Srokecz and Peter Challenor of the Southampton Oceanography Centre, calculate
An international team of astronomers has used the UKs 2.5-m Isaac Newton Telescope on La Palma in the Canary Islands to map the Andromeda Galaxy (otherwise known as M31) and a large area of sky all around it. Their work over the last few years has created the most detailed image of a large spiral galaxy that currently exists.
Dr Mike Irwin of the University of Cambridge, one of the team leaders, reports on some of the latest findings on Wednesday 31 March, when he will tell the RAS Nat
