The First Methane Dwarf Orbiting a Dead Star
23 November 2010: An international team of astronomers has used ESO telescopes and other facilities to discover and study a unique and exotic star system comprised of a very cool, methane-rich (or T-) dwarf star and a “dead” white dwarf star in orbit around each other. The system is a “Rosetta Stone” for T-dwarf stars, giving scientists a way of finding the mass and age of this old methane dwarf. The team, led by Dr Avril Day-Jones of the Universidad de Chile and composed of astronomers from the University of Hertfordshire (UK), and the University of Montreal (Canada), is publishing its results in the journal Monthly Notices of the Royal Astronomical Society. The system is the first of its type to be found. Methane is a fragile molecule destroyed at warmer temperatures, so is only seen in very cool stars and giant planets like Jupiter. Neither giant planets nor T-dwarf stars are massive ...

Café & Kosmos 8 November 2010
4 November 2010: Astronomers need patience: at the next Café & Kosmos Dr Stefan Gillessen will explain how astrophysicists at the Max-Planck Institute for Extraterrestrial Physics found a supermassive black hole at the centre of our galaxy — after collecting 16 years worth of data. This black hole is four million times more massive than our Sun, but it doesn’t shine. During a clear night, you can easily see the star-spangled band of the Milky Way. However its centre is hidden behind dense gas and dust clouds, but astronomers can use modern infrared cameras to penetrate this veil and observe the stars at the galactic centre. Just as the planets orbit the Sun, these stars orbit an invisible object. Why does this have to be a black hole? Why do we think that all galaxies harbour such gravity monsters? Come to Café & Kosmos and find out! The Café & Kosmos series of ...

Light from Four Telescopes Combined at ESO's Paranal Observatory
4 November 2010: Light coming from the four 1.8-metre Auxiliary Telescopes at the European Southern Observatory’s Very Large Telescope Interferometer (VLTI) based in Paranal, Chile, has been successfully combined for the first time using a new visiting instrument called PIONIER [1]. This is an important step towards unleashing the full potential of the VLTI to use multiple telescopes together to reveal fine detail in distant objects. A joint team from Grenoble LAOG [2] and ESO achieved this very challenging feat of engineering only five days after unpacking the equipment on the mountain. The VLTI engineers had to control the distance traversed by the light from the widely separated telescopes with an accuracy of about one hundredth of the thickness of a strand of human hair. Once the light reached PIONIER, it was then channelled into the heart of the instrument: a remarkable optical circuit [3], smaller than a credit card, that finally brought ...

Press Invitation to Launch of EVALSO, An Important Advance in Communications for Remote Latin American Observatories
28 October 2010: On Thursday 4 November 2010, ESO’s powerful telescopes, which are located in a remote and barren desert landscape in Chile, will become more accessible than ever to astronomers in Europe, thanks to a new high-speed data link. Members of the press are invited to attend the launch of the new communications data link and to view a demonstration of the technology from the project site in the middle of the Atacama Desert. The high-speed data link is part of the Enabling Virtual Access to Latin American Southern Observatories (EVALSO) project. Previously, data from instruments at the Very Large Telescope (VLT) were sent back via a microwave link to a base station near the Chilean city of Antofagasta and from there to Santiago. This link supports a data transfer rate of only 16Mbit/s, but, since ESO’s VISTA telescope saw first light in December 2009, the Paranal Observatory now produces over 100 ...

ESOcast 22: The Most Distant Galaxy Ever Measured
21 October 2010: An international team of astronomers using ESO’s Very Large Telescope has measured the distance to the most remote galaxy known so far. This is the first time that scientists have been able to confirm that they are observing a galaxy as it was in the era of reionisation — when the first generation of brilliant stars stripped out the opaque hydrogen fog filling the young Universe, thus making it transparent and ending the cosmic Dark Ages. In the latest ESOcast host Dr J explains how the historic observations were made, and the science that can be learned from them. The ESOcast is available in multiple formats, including HD. Episodes can also be watched or downloaded directly from iTunes.

Pinning Down an Asteroid Collision
13 October 2010: Astronomers have used the ESO New Technology Telescope (NTT) and other ground-based telescopes, in conjunction with the ESA spacecraft Rosetta to study a very strange celestial object that resembles a highly unusual comet tail. Using the new observations they could reconstruct the sequence of events, and concluded that, in the first half of February 2009, a small rock with a diameter of only a few meters smashed into the asteroid P/2010 A2. This high-speed collision created the trail of dust that was discovered as the bizarre “comet”. The result is also confirmed by independent results from the NASA/ESA Hubble Space Telescope. To work out the history of this unique event, Colin Snodgrass (Max Planck Institute for Solar System Research and ESO) and collaborators have combined images from ground and space, including those taken from a very different position by the Rosetta probe, which is currently far out in the Solar ...

European Virtual Observatory Shows that Galaxies like the Milky Way Form Easily
10 October 2010: A new study has confirmed that galaxies like the Milky Way form easily. The investigation, carried out by Kambiz Fathi at the Institute of Astronomy of Stockholm University, also shows that Milky-Way-sized galaxies have been the biggest spiral galaxies for at least the last 3.4 billion years of the Universe’s 13.7-billion-year history. To come to his conclusions, Fathi measured images of 30 000 galaxies, using the facilities of the European Virtual Observatory (EURO-VO) [1]. ESO is a co-leader of the EURO-VO Facility Centre. Virtual Observatories allow astronomers to use the power of the internet and large databases to re-use and combine existing observations from many different telescopes in innovative ways. For each of the 30 000 galaxies, he estimated the number of stars in the parts of galaxies where spiral arms are prominent, using images from the Sloan Digitized Sky Survey telescope [2]. The Sun occupies just such a place in the ...
