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.

Galileo satellite arrives at ESA-ESTEC for testing

One of the two Galileo satellites currently under development, GSTB-V2/A, has arrived at ESA’s European Space Research and Technology Centre to undergo testing.

Two satellites are being developed for the Galileo System Test Bed – Version 2, which will make up the first phase of in the ’in-orbit validation’ of the Galileo system.

The primary mission of the first Galileo satellites is to secure the Galileo frequency filings, validate new technologies for operational use, c

Scientists weather a space storm to find its origin

A team of researchers from the UK and France used SOHO, ACE and the four Cluster spacecraft to study a huge eruption on the Sun, tracing its progress from birth to when it reached Earth.

The team, led by scientists from University College London, identified the source of a ‘coronal mass ejection’ (CME) and analysed how its magnetic field changes on its path to Earth.

Triggered by a massive explosion on the Sun with millions of times more energy than a nuclear bomb, these

A new spin on silicon

’Orbitronics’ could keep silicon-based computing going after today’s technology reaches its limits

For about 40 years, the semiconductor industry has been able to continually shrink the electronic components on silicon chips, packing ever more performance into computers. Now, fundamental physical limits to current technology have the industry scouring the research world for an alternative. In a paper published in the Aug. 1 online edition of Physical Review Letters

UA team heads for launch of mars reconnaissance orbiter and hirise

NASA plans to launch a new orbiter called Mars Reconnaissance Orbiter (MRO) on Aug. 10 as the next step in its ambitious Mars exploration program. MRO will return more data about the red planet than all previous Mars missions combined, according to the U.S. space agency. More than 40 University of Arizona researchers, family members and friends leave for NASA’s Kennedy Space Center in Florida next week to cheer the launch. The soon-to-fly orbiter payload includes UA’s High

VLT Enables Most Accurate Distance Measurement to Spiral Galaxy NGC 300

An international team of astronomers from Chile, Europe and North America [1] is announcing the most accurate distance yet measured to a galaxy beyond our Milky Way’s close neighbours. The distance was determined using the brightness variation of a type of stars known as “Cepheid variables”.

The team used the ISAAC near-infrared camera and spectrometer on ESO’s 8.2-m VLT Antu telescope to ob

’Smart’ nanoprobes light up disease

Quantum dots programmed to glow in presence of enzyme activity

Researchers from Rice University’s Center for Biological and Environmental Nanotechnology (CBEN) have developed a “smart” beacon hundreds of times smaller than a human cell that is programmed to light up only when activated by specific proteases. Altered expression of particular proteases is a common hallmark of cancer, atherosclerosis, and many other diseases.
