Virtual Telescope Observes Record-Breaking Asteroid New data show that '2001 KX76' is larger than Ceres [heic0110]
Ceres, the first asteroid (minor planet) to be discovered in the Solar System, has held the record as the largest known object of its kind for two centuries. However, recent observations at the European Southern Observatory with the worlds first operational virtual telescope, Astrovirtel, have determined that the newly discovered distant asteroid '2001 KX76' is significantly larger, with a diameter of 1200 km, possibly even 1400 km.

Mars Express passes milestone with flying colours
As space engineers and scientists met last month for a final review of the Mars Express spacecraft design, the spacecraft itself was taking shape at the premises of Alenia, Torino, Italy. "Normally, we would have the critical design review (CDR) after tests of the spacecraft structural model (SM tests) have been completed. But because of the tight schedule for Mars Express, most of the review had to be completed early. We've done all the reviewing we can. A few items have to wait until after the SM tests," says Rudi Schmidt, Mars Express Project Manager.

MIRO at Comet Wirtanen: what a gas!
What do a comet, the Voyager mission, the Big Bang and the search for extraterrestrial intelligence have in common? Answer: Dr. Samuel Gulkis from NASA's Jet Propulsion Laboratory, Principal Investigator for the Microwave Instrument for the Rosetta Orbiter (MIRO), has played a leading role in each of them.

Cluster tunes in to the dawn chorus
The vacuum of space is hardly a suitable habitat for birds, but someone tuning in to the signals detected by the Wide Band Data (WBD) experiment on ESA's Cluster spacecraft might be forgiven for thinking that this was not the case.

SOHO's guidebook to the Sun's extreme ultraviolet light
The world's astronomers now have access to amazing details about the invisible ultraviolet light from the Sun, thanks to a new 'spectral atlas' prepared with the SUMER instrument on the SOHO spacecraft. It shows bright emissions at more than 1100 distinct wavelengths, more than 150 of which were not recorded or not identified before SOHO. The atlas is being presented today at an international meeting of astronomers, by Werner Curdt of Germany's Max-Planck-Institut f|r Aeronomie, the lead laboratory for the SUMER instrument.

X-ray emission from the jets of infant stars
Studying distant stars and their planets in different states of evolution is of great interest to astronomers and of immense importance for astronomy. XMM-Newton has added its contribution with an observation of a stellar system, L1551 IRS5. It has enabled ESAs X-ray observatory to detect for the first time the X-ray emission from its spectacular jets.

Surfing in Sagittarius not for the faint-hearted! [heic 0109]
Hubble observations have revealed huge waves sculpted in the Red Spider Nebula. This warm and windy planetary nebula harbours one of the hottest stars in the Universe and its powerful stellar winds generate waves 100 billion kilometres high intimidating for even the bravest space surfers.

ALICE arrives in Italy
A miniaturised experiment that will help to unveil the mysteries of a comet is the latest of the instruments that will fly on ESA's Rosetta Orbiter to be delivered to Italy. The ALICE ultraviolet (UV) spectrometer, which arrived at the Turin plant of Alenia Spazio earlier this week, has already been tested and integrated on the Rosetta spacecraft.

Good vibrations for SMART-1
To survive the physical stresses associated with launch, a spacecraft and its payload must be solidly built and well tested. Each spacecraft built for an ESA science mission is unique and so must undergo its own 'baptism of fire' to prove that it can withstand the launch and reach its orbit in perfect shape ready to carry out its mission.

Hubble images remarkable double cluster [heic0108]
The Double Cluster NGC 1850 found in one of our neighbouring galaxies, the Large Magellanic Cloud, is an eye-catching object. It is a young globular-like star cluster - a type of object unknown in our own Milky Way galaxy. Moreover, NGC 1850 is surrounded by a pattern of filamentary nebulosity thought to have been created during supernova blasts.
