1001 Hawaiian Nights Dedicated to the Cool and the Far Away!

British astronomers today (June 24th) saw the first images from an ambitious new programme of discovery, the UKIRT Infrared Deep Sky Survey (UKIDSS). The survey will scour the sky with the world’s most powerful infrared survey camera ( WFCAM) to find some of the dimmest and most distant objects in the Universe. UKIDSS will reach at least twenty times deeper than the largest current survey conducted at this wavelength. Infrared light can be used to study objects that are not hot enough to sh

Bioinformatics Reveals New Gene Regulation System

By comparing 140 sequenced bacterial genomes, researchers have uncovered a system for regulating genes essential to bacterial replication – and they did it solely by computer keystrokes and mouse clicks.

Mikhail Gelfand, a Howard Hughes Medical Institute international research scholar at the Institute for Information Transmission Problems (IITP) in Moscow, and his postdoctoral fellow, Dmitry Rodionov, used comparative genomics to identify a new transcription factor system in

Mars Express radar ready to work

MARSIS, the Mars Advanced Radar for Subsurface and Ionosphere Sounding on board ESA’s Mars Express orbiter, is now fully deployed, has undergone its first check-out and is ready to start operations around the Red Planet.

With this radar, the Mars Express orbiter at last has its full complement of instruments available to probe the planet’s atmosphere, surface and subsurface structure.

MARSIS consists of three antennas: two ‘dipole’ booms 20 metres long, and one 7-metre ‘mo

Dust belt around nearby star clear sign of exoplanet

Dusty disk around Fomalhaut makes ideal laboratory for studying planet formation

Astronomers zooming in on a nearby star with NASA’s Hubble Space Telescope have discovered unmistakable evidence of a planetary system: a perturbed dusty belt around the star that’s analogous to the vast Kuiper Belt of icy rocks encircling the sun.

While the discovery is expected to send astronomers scurrying to their telescopes to obtain direct images of a planet around the star, called F

Physicists clarify exotic force, but no ’Theory of Everything’ yet

The quest for a single theory that unites all of the universe’s fundamental forces has thus far eluded physicists, but that has not stopped a team of them from clearing the way for nanotechnologists while they look for it.

The group, which includes Purdue University’s Ephraim Fischbach, has recently completed research that improves our understanding of how tiny objects placed very close together can influence each other. Their experiment, which involves the behavior of

Smooth deployment for second MARSIS antenna boom

The second 20-metre antenna boom of the MARSIS instrument on board Mars Express was successfully – and smoothly – deployed, confirmed today by the ground team at ESA’s European Space Operations Centre.

The command to deploy the second MARSIS boom was given to the spacecraft at 13:30 CEST on 14 June 2005. Shortly before the deployment started, Mars Express was set into a slow rotation to last 30 minutes during and after the boom extension. This rotation allowed all the boom’s hing
