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.
For the first time, astronomers are able to predict when major flares–enormous explosions that shoot hot gases into space–will erupt on stars outside our solar system, according to research to be published in an upcoming issue of the Astrophysical Journal.
The research is based on data from the longest-running continuous radio survey of flares produced by two types of binary systems, each containing a pair of stars under the influence of each others gravity. Stars in both binary sys
On 27 August 2003, Mars is less than 56 million kilometres away – approaching closer to our planet than it has done in over 60 000 years.
About the same time as this closest approach, Mars Express passes the halfway mark of its journey, in terms of distance along its trajectory. On 1 September 2003, as it hurtles through space at 10 800 kilometres per hour, the spacecraft will have covered over 242 million kilometres, half of the total of 485 million kilometres needed to arrive at Mar
Making a landmark event in the history of the experimental investigation of plutonium, scientists from the Lawrence Livermore National Laboratory for the first time have fully mapped the phonons in gallium-stabilized delta plutonium.
The experiment promises to reveal much about the physics and material properties of plutonium and its alloys.
The research, conducted in collaboration with researchers at the European Synchrotron Radiation Facility in Grenoble, France, and the Univers
Nowadays, the Universe is pervaded by energetic ultraviolet radiation, produced by quasars and hot stars. The short-wavelength photons liberate electrons from the hydrogen atoms that make up the diffuse intergalactic medium and the latter is therefore almost completely ionised. There was, however, an early epoch in the history of the Universe when this was not so.
The Universe emanated from a hot and extremely dense initial state, the so-called Big Bang. Astronomers now believe that it took
As well as keeping their fingers crossed for good weather during next weeks close approach of Mars, astronomers are hoping that the skies will be clear on Mars itself.
During National Astronomy Week – Saturday 23 to Saturday 30 August – observing events will be held across the UK where the public can view Mars through telescopes. It is expected that thousands of people will turn out to see the planet closer than it has been for almost 60,000 years. But its not just our own
Until ten years ago, most astronomers did not believe stardust could enter our Solar System. Then ESAs Ulysses spaceprobe discovered minute stardust particles leaking through the Suns magnetic shield, into the realm of Earth and the other planets. Now, the same spaceprobe has shown that a flood of dusty particles is heading our way.
Since its launch in 1990, Ulysses has constantly monitored how much stardust enters the Solar System from the interstellar space around it. Usi
