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.

Materials On The Nanoscale May Sometimes Be Subject To The Same Physical Rules As Their Macro-World Counterparts

Researchers at the Georgia Institute of Technology and NASA suggest that materials on the nanoscale may sometimes be subject to the same physical rules as their macro-world counterparts. The findings provide an exception to the conventional scientific notion that objects small enough to be measured in nanometers (one-billionth of a meter) behave according to different rules than larger objects.

Aura Launch Rescheduled For July 13

The launch of NASA’s Aura spacecraft atop a Boeing Delta II rocket is rescheduled for Tuesday, July 13. Launch is set for the opening of a three-minute window at 6:01:59 a.m. EDT (3:01:59 a.m. PDT). Yesterday, during routine pre-launch checks, engineers discovered an improper assembly of the fairing ordnance detonator connector within the Delta II booster fairing. This detonator acts to separate the fairing during flight. Mission managers decided an additional 48 hours was need

High Value Semiconducting Carbon Nanotubes

Moore’s Law states that the number of transistors on a chip doubles every eighteen months. However current silicon technologies are approaching the limits imposed by quantum mechanics, which will stop Moore’s Law in its tracks within 20 years. New materials and techniques must be found to complement and increase the capabilities of the current silicon technologies to maintain the growth and profitability of the semi-conductor industry.

Semiconducting carbon nanotubes can be doped like sili

Northern rim of Hellas basin

These images (see link) of the rim of the Hellas basin on Mars were obtained by the High Resolution Stereo Camera (HRSC) on board ESA’s Mars Express spacecraft.

The scenes show a portion of the northern region of the Hellas basin at 29° S latitude and 68° E longitude. They were taken during orbit 488 with a resolution of 18.3 metres per pixel. North is to the right.

The Hellas basin is located in the Martian southern hemisphere, and is actually a giant impact crater. It is abo

’Light On A Chip’ Potential Seen By Scientists Spoofing Natural Phenomenon

An ultrafine nanometre ’drill’ could be used to make some of the tiniest lenses imaginable and may also allow scientists to harness light for use in optical computers of the future, thanks to research published today.

Scientists from the UK and Spain describe in this week’s Science Express (8 July) how artificial materials with tiny grooves and holes drilled into their surfaces could channel and focus light beams on a chip.

When light hits the surface of a metal such

Old Galaxies in the Young Universe

Very Large Telescope Unravels New Population of Very Old Massive Galaxies

Current theories of the formation of galaxies are based on the hierarchical merging of smaller entities into larger and larger structures, starting from about the size of a stellar globular cluster and ending with clusters of galaxies. According to this scenario, it is assumed that no massive galaxies existed in the young universe.

However, this view may now have to be revised. Using the multi-mode F
