Helicopter flight over ’Galileo valley’ guides future satnav
Helicopter flight over 'Galileo valley' guides future satnav A helicopter recently flew over a very special Alpine valley to gather data on how Europe's two satellite navigation systems - EGNOS and Galileo - will work together in future. The helicopter flew a variety of manoeuvres, from fast loops to mid-air hovering, to see how satnav signals were received in practice.

Astronomers report dark matter ’halos’ may contain stars, disprove other theories
Could it be that dark matter "halos" — the huge, invisible cocoons of mass that envelop entire galaxies and account for most of the matter in the universe — aren't completely dark after all but contain a small number of stars? Astronomers from UCLA, UC Irvine and elsewhere make a case for that in the Oct.

Scientists begin effort to stir up a cosmic dynamo in the lab
A heated electron emitting cathode (the bright spot at center) lights up the interior of a three-meter cast aluminum sphere used to contain plasmas, in an effort to create the kind of dynamo observed at the center of the Earth, sun and many other types of stars. Photo: Cary Forest laboratory For scientists trying to understand the subtleties of cosmic dynamos — the magnetic field-inducing phenomena at the hearts of planets, stars and galaxies — the physics, for the most part, must be done at vast distances.

The Solar System's grandest canyon
The Solar System’s grandest canyon
Earth's Grand Canyon inspires awe for anyone who casts eyes upon the vast river-cut valley, but it would seem nothing more than a scratch next to the cavernous scar of Valles Marineris that marks the face of Mars. Stretching over 4000 km long and 200 km wide, and with a dizzying depth of 10 km, it is some ten times longer and five times deeper than Earth's Grand Canyon, a size that earns it the status of the largest canyon in the Solar System.

Split-Personality Elliptical Galaxy Holds a Hidden Spiral
Cambridge, MA - Most big galaxies fit into one of two camps: pinwheel-shaped spiral galaxies and blobby elliptical galaxies. Spirals like the Milky Way are hip and happening places, with plenty of gas and dust to birth new stars. Ellipticals are like cosmic retirement villages, full of aging residents in the form of red giant stars.

Opening new windows on the Universe
We'll be able to look for evidence of unintentional radio emissions, the equivalent of airport radar, from our nearby stars and planetary systems that may indicate intelligent life." How do planetary systems form? What do the surfaces of stars look like? Does life exist elsewhere in the Universe? Astronomers have developed many theoretical models, but until now the ability to validate these with observations has been severely constrained by the telescope capabilities available.

Large water reservoirs at the dawn of stellar birth
Large water reservoirs at the dawn of stellar birth times over, in a gas and dust cloud that is on the verge of collapsing into a new Sun-like star. Stars form within cold, dark clouds of gas and dust - 'pre-stellar cores' - that contain all the ingredients to make solar systems like our own. Water, essential to life on Earth, has previously been detected outside of our Solar System as gas and ice coated onto tiny dust grains near sites of active star formation, and in proto-planetary discs capable of forming alien planetary systems.

ESA satellites looking deeper into sea ice This year, satellites saw the extent of Arctic sea ice hit a record low since measurements began in the 1970s. ESA's SMOS and CryoSat satellites are now taking a deeper look by measuring the volume of the sea-ice cover. Watch the animation in full resolution Measurements from ESA's Soil Moisture and Ocean Salinity (SMOS) mission show that ice has thinned significantly in the seasonal ice zones, with extensive areas less than half a metre thick.

Ice-coated beauty in Mars' Silver Island
Ice-coated beauty in Mars’ Silver Island
On 8 June, the high-resolution stereo camera on Mars Express captured a region within the 1800 km-wide and 5 km-deep Argyre basin, which was created by a gigantic impact in the planet's early history. After Hellas, the Argyre impact basin is the second largest on the Red Planet. The name stems from the Greek word 'argyros' (silver) and Argyre was an 'island of silver' in Greek and Roman mythology.

Comet crystals found in a nearby planetary system Pristine material that matches comets in our own Solar System have been found in a dust belt around the young star Beta Pictoris by ESA's Herschel space observatory. Twelve-million-year-old Beta Pictoris resides just 63 light-years from Earth and hosts a gas giant planet along with a dusty debris disc that could, in time, evolve into a torus of icy bodies much like the Kuiper Belt found outside the orbit of Neptune in our Solar System.

Rapid ice shelf disintegration in Antarctic
Rapid ice shelf disintegration in Antarctic
For ten years ESA's Envisat satellite observed the rapid retreat of one of Antarctica's ice shelves due to climate warming. Helmut Rott, Professor at the Institute of Meteorology and Geophysics, follows this development since the start of the mission. One of the satellite's first observations following its launch on 1 March 2002 was the break-up of a main section of the Larsen B ice shelf in Antarctica - when 3200 sq km of ice disintegrated within a few days due to mechanical instabilities of the ice masses triggered by climate warming.
