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.

Scientists create artificial cricket hairs

Scientists have re-created one of nature’s most sensitive sound detectors – the tiny hairs found on body parts of crickets, which allow them to hear predators and make an escape before they get close enough to catch them. Published today (20th June 2005) in the Journal of Micromechanics and Microengineering, an Institute of Physics journal, this research will help scientists understand the complex physics that crickets use to perceive their surroundings and could lead to a new generation of

’Strange’ physics experiment is unraveling structure of proton

An international team of nuclear physicists has determined that particles called strange quarks do, indeed, contribute to the ordinary properties of the proton.

Quarks are subatomic particles that form the building blocks of atoms. How quarks assemble into protons and neutrons, and what holds them together, is not clearly understood. New experimental results are providing part of the answer.

The experiment, called G-Zero, was performed at Thomas Jefferson National Accelera

Physicists clarify exotic force, but no ’Theory of Everything’ yet

The quest for a single theory that unites all of the universe’s fundamental forces has thus far eluded physicists, but that has not stopped a team of them from clearing the way for nanotechnologists while they look for it.

The group, which includes Purdue University’s Ephraim Fischbach, has recently completed research that improves our understanding of how tiny objects placed very close together can influence each other. Their experiment, which involves the behavior of

SMART-1’s tribute to Cassini

This image from SMART-1 was dedicated to the Cassini-Huygens mission team at the occasion of the European Geoscience Union conference in Vienna, April 2005, when new results from both missions were presented.

The crater Cassini on our Moon was named in honour of Jean-Dominique Cassini, one of the most important scientists of the 17th and 18th centuries. The joint NASA/ESA/ASI spacecraft, which is now in orbit around Saturn as part of the Cassini-Huygens mission, bears his name.

G-Zero Finds that Ghostly Strange Quarks Influence Proton Structure

In research performed at the Department of Energy’s Jefferson Lab, nuclear physicists have found that strange quarks do contribute to the structure of the proton. This result indicates that, just as previous experiments have hinted, strange quarks in the proton’s quark-gluon sea contribute to a proton’s properties. The result comes from work performed by the G-Zero collaboration, an international group of 108 physicists from 19 institutions and was presented at a Jefferson Lab phy

Pioneering technology to explore other planets

Drilling holes on other planets and inventing novel textiles to secure large structures in space are just two of the 27 challenges that expert teams have been working on in the first year of ESA’s Innovation Triangle Initiative.

“By combining the creativity of the inventor, the needs of end users and the production experience of industry we have created strong drive and a very successful synergy to identify, demonstrate and verify novel ideas for future space technologies,” says Mar
