The world’s most sensitive Gamma Ray telescopes are being inaugurated in Namibia (in Southwest Africa) on September 3rd. The High Energy Stereoscopic System (H.E.S.S.), a European/African collaboration in which the UK is a partner, will look for Gamma Rays produced by the most energetic particles in the Universe. The array initially consists of four telescopes, the first of which will become operational next week. This one telescope alone is more sensitive than any other existing ground-based array or telescope working in this particular area of the electromagnetic spectrum.
Once all four telescopes are operational in late 2003, researchers from the University of Durham will use H.E.S.S. to investigate a range of extreme cosmic environments such as the supernova remnants formed when a star dies. A major goal is to see if these are a source of cosmic rays - charged particles that constantly bombard the Earth from space. The origin of cosmic rays is difficult to determine as they are influenced by the magnetic field of our Galaxy. However, the Gamma Rays they emit travel in a straight line, so they may reveal the primary source of the cosmic rays. H.E.S.S. will also be probing the structure of pulsars (rapidly rotating stars formed when a massive star explodes at the end of its life, which emit pulses across the range of the electromagnetic spectrum) and active galactic nuclei to find the source of their energy.
Dr Paula Chadwick, of the Durham team, explains: "H.E.S.S. is set to give us unique insights into some of the most extreme environments in the universe. We have some expectations about what we will be able learn more about - supernova remnants, active galaxies and so on - but experience tells us that when you improve the sensitivity of your telescope, you see things you never expected as well. It`s going to be very exciting!"

Soft robots have a distinct advantage over their rigid forebears: they can adapt to complex environments, handle fragile objects and interact safely with humans. Made from silicone, rubber or other stretchable polymers, they are ideal for use in rehabilitation exoskeletons and robotic clothing. Soft bio-inspired robots could one day be deployed to explore remote or dangerous environments.
Most soft robots are actuated by rigid, noisy pumps that push fluids into the machines' moving parts. Because they are connected to these bulky pumps by tubes,...
Researchers at TU Graz are working together with European partners on new possibilities of measuring vehicle emissions.
Today, air pollution is one of the biggest challenges facing European cities. As part of the Horizon 2020 research project CARES (City Air Remote Emission...
Over the next three years, researchers from the Vrije Universiteit Brussel, University of Cambridge, École Supérieure de Physique et de Chimie Industrielles de la ville de Paris (ESPCI-Paris) and Empa will be working together with the Dutch Polymer manufacturer SupraPolix on the next generation of robots: (soft) robots that ‘feel pain’ and heal themselves. The partners can count on 3 million Euro in support from the European Commission.
Soon robots will not only be found in factories and laboratories, but will be assisting us in our immediate environment. They will help us in the household, to...
Scientists at the University of Leeds have created a new form of gold which is just two atoms thick - the thinnest unsupported gold ever created.
The researchers measured the thickness of the gold to be 0.47 nanometres - that is one million times thinner than a human finger nail. The material is regarded...
An international team of scientists involving the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) in Hamburg has unraveled the light-induced electron-localization dynamics in transition metals at the attosecond timescale. The team investigated for the first time the many-body electron dynamics in transition metals before thermalization sets in. Their work has now appeared in Nature Physics.
The researchers from ETH Zurich (Switzerland), the MPSD (Germany), the Center for Computational Sciences of University of Tsukuba (Japan) and the Center for...
