Why is the Hercules Dwarf Galaxy so flat?

Through some of the very first scientific observations with the brand-new Large Binocular Telescope (LBT) in Arizona, an international team of astronomers has found that a recently discovered tiny companion galaxy to our ...

'Radio Wave Cooling' Offers New Twist on Laser Cooling

Visible and ultraviolet laser light has been used for years to cool trapped atoms—and more recently larger objects—by reducing the extent of their thermal motion. Now, applying a different form of radiation for a similar ...

'Guide to Secure Web Services' provides blueprint to safer Web 2.0

Many Web-based services, from shopping to online word processing, allow computer programs to talk to each other and exchange user data across several Web sites without human intervention. Many of the attractive features of ...

Probing a rare material spin state

A team of international physicists that includes researchers from the National Institute of Standards and Technology has found experimental evidence of a highly sought-after type of arrangement of atomic magnetic moments, ...

The missing link in the evolution of magnetic cataclysmic stars?

An international team of astronomers might have discovered the missing link in the evolution of the so-called magnetic cataclysmic variable stars. They determined the spin and orbital periods of the binary star Paloma. They ...

Lift-off for Foton microgravity mission

An unmanned Foton spacecraft, carrying a payload of more than 40 ESA experiments, was successfully launched earlier today. The Soyuz-U launcher lifted off from Baikonur Cosmodrome, Kazakhstan, at 13:00 CEST (11:00 GMT).

Satellites witness lowest Arctic ice coverage in history

The area covered by sea ice in the Arctic has shrunk to its lowest level this week since satellite measurements began nearly 30 years ago, opening up the Northwest Passage – a long-sought short cut between Europe and Asia ...

Galaxy 'hunting' made easy

Astronomers using ESO's Very Large Telescope have discovered in a single pass about a dozen otherwise invisible galaxies halfway across the Universe. The discovery, based on a technique that exploits a first-class instrument, ...
