The Cosmic Christmas Ghost
25 de Diciembre de 2005: Just like Charles Dickens' Christmas Carol takes us on a journey into past, present and future in the time of only one Christmas Eve, two of ESO' s telescopes captured various stages in the life of a star in a single image.

ALMA on the Move
22 de Diciembre de 2005: Only two weeks after awarding its largest-ever contract for the procurement of antennas for the Atacama Large Millimeter Array project (ALMA), ESO has signed a contract with Scheuerle Fahrzeugfabrik GmbH, a world-leader in the design and production of custom-built heavy-duty transporters, for the provision of two antenna transporting vehicles. These vehicles are of crucial importance for ALMA.

Allo, Allo? A Star is Ringing
21 de Diciembre de 2005: Astronomers have used ESO's Very Large Telescope in Chile and the Anglo-Australian Telescope in eastern Australia as a 'stellar stethoscope' to listen to the internal rumblings of a nearby star. The data collected with the VLT have a precision better than 1.5 cm/s, or less than 0.06 km per hour!

Witnessing the Flash from a Black Hole's Cannibal Act
14 de Diciembre de 2005: An international team of astronomers reports the discovery of a third short gamma-ray burst, associated with a nearby elliptical galaxy. The low level of star formation in such galaxies and the detection of a second long-lasting flare indicate that this gamma-ray burst is most likely the final scream of a neutron star as it is being devoured by a black hole.

ESO Signs Largest-Ever European Industrial Contract For Ground-Based Astronomy Project ALMA
7 de Diciembre de 2005: ESO, the European Organisation for Astronomical Research in the Southern Hemisphere, announced today that it has signed a contract with the consortium led by Alcatel Alenia Space and composed also of European Industrial Engineering (Italy) and MT Aerospace (Germany), to supply 25 antennas for the Atacama Large Millimeter Array (ALMA) project, along with an option for another seven antennas. The contract, worth 147 million euros, covers the design, manufacture, transport and on-site integration of the antennas. It is the largest contract ever signed in ground-based astronomy in Europe.

OBSERVATORIO LA SILLA ENCONTRÓ EXOPLANETA DEL TAMAÑO DE NEPTUNO
30 de Noviembre de 2005: Astrónomos franceses y suizos descubrieron uno de los planetas extrasolares más ligeros que se conocen usando el instrumento HARPS del telescopio de 3,6 metros de ESO en La Silla, IV Región.

Sharp Vision Reveals Intimacy of Stars
24 de Noviembre de 2005: Using the newly installed AMBER instrument on ESO's Very Large Telescope Interferometer, which combines the light from two or three 8.2-m Unit Telescopes thereby amounting to observe with a telescope of 40 to 90 metres in diameter, two international teams of astronomers observed with unprecedented detail the environment of two stars. One is a young, still-forming star and the new results provide useful information on the conditions leading to the creation of planets. The other is on the contrary a star entering the latest stages of its life. The astronomers found, in both cases, evidence for a surrounding disc.

Setting the Stage for Science in Schools
10 de Noviembre de 2005: How can you weigh the Earth with a straw, a paperclip and a piece of thread? Why don't we really know what we see? How can a juggling act explain mathematics? These are but a few of the on-stage activities that will be shown at the EIROforum [1] Science on Stage Festival, to be held from 21 to 25 November at CERN in Geneva (Switzerland). With support from the European Commission, this international festival brings together around 500 science educators from 29 European countries to show how fascinating and entertaining science can be.

VLT captura estrella fugitiva
9 de Noviembre de 2005: Desde el Observatorio Paranal (II Región) se logró fotografiar una estrella que recorre el espacio a una velocidad de 2,6 millones de kilómetros por hora, y que habría sido expulsada por la Nube Grande de Magallanes.

RETRATO DE UNA FAMILIA CÓSMICA
4 de Noviembre de 2005: Una fotografía captada por el Very Large Telescope de ESO en Cerro Paranal (II Región de Chile), muestra detalles asombrosos de un grupo de galaxias conocidas como el Cuarteto de Robert.

Feeding the Monster
17 de Octubre de 2005: Near-infrared images of the active galaxy NGC 1097, obtained with the NACO adaptive optics instrument on ESO's Very Large Telescope, disclose with unprecedented detail a complex central network of filamentary structure spiralling down to the centre of the galaxy. These observations provide astronomers with new insights on how super-massive black holes lurking inside galaxies get fed.

TELESCOPIOS EN CHILE AYUDAN A RESOLVER MISTERIO DE EXPLOSIONES DE RAYOS GAMA
6 de Octubre de 2005: Astrónomos utilizan telescopios de La Silla y Paranal para detectar el resplandor de esquivas y breves explosiones, las más poderosas en el universo después del Big-Bang.

The Colossal Cosmic Eye
29 de Septiembre de 2005: Astronomers have released a new, stunning picture of the spiral galaxy NGC 1350. Resembling the shape of an eye, the galaxy exhibits a double ring structure whose blue glow reveals the presence of many young stars.

Inauguran en norte de Chile telescopio submilimétrico más grande del hemisferio sur
25 de Septiembre de 2005: Con sus 12 metros de diámetro, la antena APEX permitirá observar el Universo desde uno de los mejores lugares del mundo para la radioastronomía: el Llano de Chajnantor, ubicado a 5100 metros de altura en el Desierto de Atacama, en la II Región de Chile.

A Cosmic Baby-Boom
22 de Septiembre de 2005: The Universe was a more fertile place soon after it was formed than has previously been suspected. A team of French and Italian astronomers [1] made indeed the surprising discovery of a large and unknown population of distant galaxies observed when the Universe was only 10 to 30% its present age.

Black Hole in Search of a Home
14 de Septiembre de 2005: An international team of astronomers [1] used two of the most powerful astronomical facilities available, the ESO Very Large Telescope (VLT) at Cerro Paranal and the Hubble Space Telescope (HST), to conduct a detailed study of 20 low redshift quasars. For 19 of them, they found, as expected, that these super massive black holes are surrounded by a host galaxy. But when they studied the bright quasar HE0450-2958, located some 5 billion light-years away, they couldn't find evidence for an encircling galaxy. This, the astronomers suggest, may indicate a rare case of collision between a seemingly normal spiral galaxy and a much more exotic object harbouring a very massive black hole.

Star Death Beacon at the Edge of the Universe
12 de Septiembre de 2005: An Italian team of astronomers has observed the afterglow of a Gamma-Ray Burst that is the farthest known ever. With a measured redshift of 6.3, the light from this very remote astronomical source has taken 12,700 million years to reach us. It is thus seen when the Universe was less than 900 million years old, or less than 7 percent its present age.

Celestial Blast in Bleak Reticulum
24 de Agosto de 2005: The southern Reticulum constellation [1] certainly isn't a big hit for amateur astronomers. This tiny, bleak and diamond-shaped constellation, not far on the sky from the Large Magellanic Cloud, is often overlooked. But recently, astronomers had a closer look at a galaxy situated inside it. And more precisely at an exploding star hosted by the spiral galaxy NGC 1559 [2].

Rubble-Pile Minor Planet Sylvia and Her Twins
11 de Agosto de 2005: One of the thousands of minor planets orbiting the Sun has been found to have its own mini planetary system. Astronomer Franck Marchis (University of California, Berkeley, USA) and his colleagues at the Observatoire de Paris (France) [1] have discovered the first triple asteroid system - two small asteroids orbiting a larger one known since 1866 as 87 Sylvia [2].
