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.

Hubble captures outburst from comet targeted by Deep Impact

In a dress rehearsal for the rendezvous between NASA’s Deep Impact spacecraft and comet 9P/Tempel 1, the Hubble Space Telescope captured dramatic images of a new jet of dust streaming from the icy comet.

The images are a reminder that Tempel 1’s icy nucleus, roughly the size of central Paris, is dynamic and volatile. Astronomers hope the eruption of dust seen in these observations is a preview of the fireworks that may come 4 July, when a probe from the Deep Impact spacecraft w

MIT Group Creates a High-Temperature Superfluid

Physicists at the Massachusetts Institute of Technology (MIT) have created the first example of a high-temperature superfluid: a new state of matter in which the atoms in a gas can move with no friction or slowing down whatsoever.

Reported in the June 23 issue of journal Nature, the work is closely related to the superconductivity of electrons in metals. According to Wolfgang Ketterle, the Nobel laureate who heads the MIT group, observations of superfluids may help solve lingering questio

Researchers get clearer view of Earth’s atmosphere — from the laboratory

For scientists who want to discern the complex chemistry at work in Earth’s atmosphere, detecting a particular gas molecule can be as hard as finding a proverbial needle in a haystack.

Frank De Lucia, professor of physics at Ohio State University , and his colleagues recently used their FAST Scan Submillimeter Spectroscopy Technique (FASSST) to make the job easier.

The technique offers a way for scientists to examine the spectrum of light given off by a molecule. E

The Shifty Nature of Grains

Qualities of granular materials provide insight into both nature and industry

In separate papers appearing in this week’s Nature, researchers announce findings regarding the little-understood world of granular materials, systems of particles that can dictate the flow of avalanches, the quality of concrete and even the mixing of pharmaceuticals.

In both studies, the researchers developed new analytical tools that combine laboratory simulators with advanced computer simu

Microbes found to produce miniature electrical wires

Researchers at the University of Massachusetts Amherst have discovered a tiny biological structure that is highly electrically conductive. This breakthrough helps describe how microorganisms can clean up groundwater and produce electricity from renewable resources. It may also have applications in the emerging field of nanotechnology, which develops advanced materials and devices in extremely small dimensions.

The findings of microbiologist Derek R. Lovley’s research team are pu

Cebreros marks major readiness milestone

On 9 June, a powerful new 35-metre antenna, presently undergoing acceptance testing at Cebreros, Spain, successfully picked up signals and tracked Rosetta and SMART-1. It is ESA’s second deep-space ground station in its class and adds Ka-band reception capability and high pointing precision to the ESTRACK network.

Construction of the new ground station, located in the Spanish province of Avila, has proceeded in record time. Procurement activities started in February 2003, and
