Physics and Astronomy
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.
First shipping forecast for the oceans of Titan
When the European Huygens probe on the Cassini space mission parachutes down through the opaque smoggy atmosphere of Saturn’s 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
Andromeda Galaxy – Cannibal On Our Doorstep?
An international team of astronomers has used the UK’s 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
Mars Express confirms methane in the Martian atmosphere
During recent observations from the ESA Mars Express spacecraft in orbit around Mars, methane was detected in its atmosphere.
Whilst it is too early to draw any conclusions on its origin, exciting as they may be, scientists are thinking about the next steps to take in order to understand more.
From the time of its arrival at Mars, the Mars Express spacecraft started producing stunning results. One of the aims of the mission is analysing in detail the chemical composition of the M
New Quasar Studies Keep Fundamental Physical Constant Constant
Very Large Telescope sets stringent limit on possible variation of the fine-structure constant over cosmological time
A fine constant
To explain the Universe and to represent it mathematically, scientists rely on so-called fundamental constants or fixed numbers. The fundamental laws of physics, as we presently understand them, depend on about 25 such constants. Well-known examples are the gravitational constant, which defines the strength of the force acting between tw
Andromeda yields cache of stellar black holes
Astronomers have discovered ten previously unknown likely black holes in the Andromeda Galaxy by means of a powerful new search technique they have devised. The Andromeda Galaxy is the nearest neighbouring spiral galaxy, 2.5 million light years away. Drs Robin Barnard, Ulrich Kolb and Carole Haswell of the Open University and Dr Julian Osborne of The University of Leicester used the European Space Agency’s XMM-Newton orbiting X-ray observatory to find what are probably black holes lurking in dou
Astronomers Look Forward To ’Swift’ Studies Of Cataclysmic Explosions
Gamma ray bursts (GRBs) are the most powerful explosions in the Universe, yet it is only in the last few years that astronomers have started to understand them. This ongoing quest to solve the mysteries of gamma ray bursts will be boosted next September when a new US/UK/Italian space observatory, called Swift, will be launched.
Dr. Julian Osborne (University of Leicester) will describe this exciting mission and the discoveries that can be expected from Swift on Tuesday 30 March, during the
