Combining precise observations obtained by ESO's Very Large Telescope with those gathered by a network of smaller telescopes, astronomers have described in unprecedented detail the double asteroid Antiope, which is shown to be a pair of rubble-pile chunks of material, of about the same size, whirling around one another in a perpetual pas de deux. The two components are egg-shaped despite their very small sizes.

Numerous astronomical results have been obtained thanks to AMBER, the instrument which equips the Very Large Telescope Interferometer (VLTI) at the European Southern Observatory (ESO). AMBER (Astronomical Multi-BEam Recombiner) makes it possible to combine the beams of three of the four 8-metre VLT telescopes.

Just days before nations around the world were set to begin a coordinated global research campaign called the International Polar Year (IPY); scientists at the South Pole aimed a massive new telescope at Jupiter and successfully collected the instrument's first test observations.

The ESO Very Large Telescope Interferometer, which allows astronomers to scrutinise objects with a precision equivalent to that of a 130-m telescope, is proving itself an unequalled success every day. One of the latest instruments installed, AMBER, has led to a flurry of scientific results, an anthology of which is being published this week as special features in the research journal Astronomy & Astrophysics.

The AMBER instrument installed at the Very Large Telescope (VLT) of the European Southern Observatory (ESO) combines the light from three 8.2 meter telescopes, making the VLT the world's largest optical telescope, with a total mirror surface larger than 150 m2 and a maximum telescope separation greater than 130 m. Two years after installation, the first astrophysical results are blossoming. They are being published this week as a special feature in Astronomy & Astrophysics.

Comet McNaught, the Great Comet of 2007, is no more visible for observers in the Northern Hemisphere. It does put an impressive show in the South, however, and observers in Chile, in particular at the Paranal Observatory, were able to capture amazing images, including a display reminiscent of an aurora!
