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.

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

Linking With The Future

Exploring and using space is the biggest adventure facing mankind. Finding innovative ways for ESA to continue doing this is the role of the Advanced Concepts Team (ACT) at ESA’s European Space Technology Research Centre (ESTEC).

It is their job to look into the future and identify ideas which could enable missions that currently sound like science fiction.

From simple “what if?” ideas, the ACT evaluate what is and is not possible. For example, among many other proposals, they are

Glimpse at Early Universe Reveals Surprisingly Mature Galaxies

Observations challenge standing view of how and when galaxies formed

A rare glimpse back in time into the universe’s early evolution has revealed something startling: mature, fully formed galaxies where scientists expected to discover little more than infants.

“Up until now, we assumed that galaxies were just beginning to form between 8 and 11 billion years ago, but what we found suggests that that is not the case,” said Karl Glazebrook, associate professor of physics and

FITS Format Liberation – DIY Astronomical Images With The Expert Touch

For many years astronomical images from the world’s telescopes were reserved for an elite of astronomers and technical people. Now anyone with a desktop computer running Adobe® Photoshop® software can try their hand at crafting astronomical images as beautiful as those from the Hubble Space Telescope. A free software plug-in, released today, makes a treasure trove of archival astronomical images and spectra from the NASA/ESA Hubble Space Telescope, the European Southern Observatory’s Very Large Tele
