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.

Internet Link Moves Gemini Closer to Becoming First "Cyber Observatory"

A unique combination of international cooperation and the latest Internet technology will allow Gemini Observatory to become the first international “cyber observatory.”

Gemini, with funding and support from the National Science Foundation (NSF), is blazing an Internet pathway that will provide its globally separated telescopes with a reliable data transfer connection. The connection will allow real-time remote observations and sharing of scientific data generated by the twin 8-meter telesc

Communicating with light polarization

A new and novel way of communicating over fiber optics is being developed by physicists supported by the Office of Naval Research. Rather than using the amplitude and frequency of electromagnetic waves, they’re using the polarization of the wave to carry the signal. Such a method offers a novel and elegant method of secure communication over fiber optic lines.

Electromagnetic waves, like light and radio waves, have amplitude (wave heigh

Jefferson Lab’s Hall C experiment delves into nature’s blueprints

Taking a closer look at matter’s blueprints with a study of the spin-structure functions of the proton and the neutron, collectively known as nucleons

Building a bridge over land or water requires careful engineering. There is the weight of passing cars and trucks to consider. Will high winds or turbulent weather threaten the structure? How deep should the concrete foundations be poured? How best to affix the steel supports? What is the ideal mix of materials for strength, durabi

Amazingly Sharp VLT Image of Lunar Landscape

Thirty-three years after the first manned landing on the Moon, the ESO Very Large Telescope (VLT) has obtained what may be the sharpest image of the lunar surface ever recorded from the ground. It was made with the NAOS-CONICA (NACO) adaptive optics camera mounted on the ESO VLT 8.2-m YEPUN telescope at the Paranal Observatory.

The photo (ESO PR Photo 19a/02) shows an area about 700 km from the Apollo XI landing site. The location

Warp speed brings Dirac into the 21st century

You`d be forgiven for thinking that an American predicted anti-matter. Or that it only existed in Star Trek. In fact, it was Paul Dirac, a Bristol born physicist, who predicted the stuff that propels starships in science fiction movies and who has also influenced much of our modern day technology, for example, computers. Today, 8 August is the centenary of Dirac`s birth. The Institute of Physics celebrates Dirac`s life and legacy in 2002, with six Manga (japanese cartoon-style) posters.

Rich and Inspiring Experience with NGC 300 Images from the ESO Science Data Archive
A series of wide-field images centred on the nearby spiral galaxy NGC 300, obtained with the Wide-Field Imager (WFI) on the MPG/ESO 2.2-m telescope at the La Silla Observatory, have been combined into a magnificent colour photo.

These images have been used by different groups of astronomers for various kinds of scientific investigations, ranging from individual stars and nebulae in NGC 300, to distant gal
