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.

Astronomers eclipse record for most distant massive object

An international team of astronomers using the world’s largest X-ray and optical telescopes have spotted the most distant massive object ever detected, a cluster of galaxies 9 billion light years distant from Earth.

The cluster of galaxies is so far away that the light detected by the team is much older than the Earth itself. The galaxy cluster, if it is even still there, would be at least 11 billion years old now. “By capturing this ancient, 9-billion-year-old light, we

Amateur watchers invited to ’Rosetta Up Close’ photo contest

Rosetta’s Earth fly-by on 4 March, ESA’s closest ever at just 1900 kilometres, will provide a fantastic photo opportunity. The ’Rosetta Up Close’ photo contest will recognize and reward the best images and sky watchers everywhere are invited to participate.

If you’ve got a decent amateur telescope and digital imaging equipment, you can probably take some impressive photos of Rosetta—weather permitting—as the craft speeds by Earth.

Scientists entice superconducting devices to act like atoms

Advance marks progress toward quantum computer made with ’artificial atoms’

Two superconducting devices have been coaxed into a special, interdependent state that mimics the unusual interactions sometimes seen in pairs of atoms, according to a team of physicists at the National Institute of Standards and Technology (NIST) and University of California, Santa Barbara (UCSB). The experiments, performed at the NIST laboratory in Boulder, Colo., are an important step toward

Saturn’s A Ring has oxygen, but not life

Data from the Cassini-Huygens satellite showing oxygen ions in the atmosphere around Saturn’s rings suggests once again that molecular oxygen alone isn’t a reliable indicator of whether a planet can support life.

That and other data are outlined in two papers in the Feb. 25 issue of the journal Science co-authored by University of Michigan engineering professors Tamas Gombosi, J. Hunter Waite and Kenneth Hansen; and T.E. Cravens from the University of Kansas. The papers b

ESA’s comet chaser to fly by Earth

ESA’s comet-chaser Rosetta will make a fly-by of planet Earth on 4 March 2005, and sky watchers should be able to see it with telescopes or binoculars if the sky is clear! Read on for details of ESA’s ’Rosetta Up Close’ photo contest.

Rosetta is approaching Earth from an area in the sky between the constellations Leo and Sextans, and should first become visible to large amateur telescopes around 26 February 2005. The spacecraft will make its closest approach to

Seeing the invisible – first dark galaxy discovered?

A British-led team of astronomers have discovered an object that appears to be an invisible galaxy made almost entirely of dark matter – the first ever detected. A dark galaxy is an area in the universe containing a large amount of mass that rotates like a galaxy, but contains no stars. Without any stars to give light, it could only be found using radio telescopes. It was first seen with the University of Manchester’s Lovell Telescope in Cheshire, and the sighting was confirmed with the Areci
