7. März 2007: New data obtained on the apparent celestial couple, NGC 5011 B and C, taken with the 3.6-m ESO telescope, reveal that the two galaxies are not at the same distance, as was believed for the past 23 years. The observations show that NGC 5011C is not a giant but a dwarf galaxy, an overlooked member of a group of galaxies in the vicinity of the Milky Way.

24. Februar 2007: The unique supernova SN 1987A has been a bonanza for astrophysicists. It provided several observational 'firsts,' like the detection of neutrinos from an exploding star, the observation of the progenitor star on archival photographic plates, the signatures of a non-spherical explosion, the direct observation of the radioactive elements produced during the blast, observation of the formation of dust in the supernova, as well as the detection of circumstellar and interstellar material.

23. Februar 2007: Comet McNaught, the Great Comet of 2007, has been delighting those who have seen it with the unaided eye as a spectacular display in the evening sky. Pushing ESO's New Technology Telescope to its limits, a team of European astronomers have obtained the first, and possibly unique, detailed observations of this object. Their images show spectacular jets of gas from the comet spiralling several thousands of kilometres into space, while the spectra reveal the presence of sodium in its atmosphere, something seen very rarely.

23. Februar 2007: 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.

19. Januar 2007: 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!

17. Januar 2007: The world's biggest infrared camera for Europe's newest telescope left the UK today for Chile. The 67 million pixel camera will equip VISTA - a UK provided survey telescope being constructed in Chile for ESO. VISTA will map the infrared sky faster than any previous telescope, studying areas of the Universe that are hard to see in the visible due to either their cool temperature, surrounding dust or high redshift.

11. Januar 2007: The ESO Council has just appointed Tim de Zeeuw, 50, as the next Director General of ESO, effective as of 1 September 2007, when the current Director General, Catherine Cesarsky will complete her mandate.

8. Januar 2007: Using ESO's Very Large Telescope and the W.M. Keck Observatory, astronomers at the Ecole Polytechnique Fédérale de Lausanne in Switzerland and the California Institute of Technology, USA, have discovered what appears to be the first known triplet of quasars. This close trio of supermassive black holes lies about 10.5 billion light-years away towards the Virgo (The Virgin) constellation.

4. Januar 2007: Last year proved to be another exceptional year for the European organisation for ground-based astronomy. ESO should begin the New Year with two new member states: Spain (PR 05/06) and Czechia (PR 52/06).

24. Dezember 2006: A Happy New Year!

22. Dezember 2006: Today, an agreement was signed in Prague between ESO and Czechia, aiming to make the latter become a full member of ESO as of 1 January 2007.

22. Dezember 2006: On the night of 15 December 2006, the fourth and last-to-be-installed VLTI Auxiliary Telescope (AT4) obtained its 'First Light'. The first images demonstrate that AT4 will be able to deliver the excellent image quality already delivered by the first three ATs. It will soon join its siblings to perform routinely interferometric measurements.

21. Dezember 2006: A new, stunning image of the cosmic spider, the Tarantula Nebula and its surroundings, finally pays tribute to this amazing, vast and intricately sculpted web of stars and gas. The newly released image, made with ESO's Wide Field Imager on the 2.2-m ESO/MPG Telescope at La Silla, covers 1 square degree on the sky and could therefore contain four times the full Moon.

20. Dezember 2006: Nature has again thrown astronomers for a loop. Just when they thought they understood how gamma-ray bursts formed, they have uncovered what appears to be evidence for a new kind of cosmic explosion. These seem to arise when a newly born black hole swallows most of the matter from its doomed parent star.

20. Dezember 2006: Astronomers at ESO's frontline Paranal Observatory got a surprise on the morning of 18 December when looking at the observatory's all-sky camera, MASCOT. For about 45 minutes in the early morning, an object appeared first as a bright stripe then as a cloud that dissolved.

14. Dezember 2006: Today, Janez Potočnik, European Commissioner for Science and Research received a statement of support for the European Charter for Researchers and the Code of Conduct for the Recruitment of Researchers from EIROforum.

11. Dezember 2006: European astronomy has received a tremendous boost with the decision from ESO's governing body to proceed with detailed studies for the European Extremely Large Telescope. This study, with a budget of 57 million euro, will make it possible to start, in three years time, the construction of an optical/infrared telescope with a diameter around 40m that will revolutionise ground-based astronomy. The chosen design is based on a revolutionary concept specially developed for a telescope of this size.

6. Dezember 2006: Using VIMOS on ESO's Very Large Telescope, a team of French and Italian astronomers have shown the strong influence the environment exerts on the way galaxies form and evolve. The scientists have for the first time charted remote parts of the Universe, showing that the distribution of galaxies has considerably evolved with time, depending on the galaxies' immediate surroundings. This surprising discovery poses new challenges for theories of the formation and evolution of galaxies.

30. November 2006: Astronomers are reporting remarkable new findings that shed light on a decade-long debate about one kind of supernovae, the explosions that mark a star's final demise: does the star die in a slow burn or with a fast bang? From their observations, the scientists find that the matter ejected by the explosion shows significant peripheral asymmetry but a nearly spherical interior, most likely implying that the explosion finally propagates at supersonic speed.

23. November 2006: The captivating appearance of this image of the starburst galaxy NGC 1313, taken with the FORS instrument at ESO's Very Large Telescope, belies its inner turmoil. The dense clustering of bright stars and gas in its arms, a sign of an ongoing boom of star births, shows a mere glimpse of the rough times it has seen. Probing ever deeper into the heart of the galaxy, astronomers have revealed many enigmas that continue to defy our understanding.
