Café & Kosmos 8 November 2010
4 de Noviembre de 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 de Noviembre de 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 de Octubre de 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 de Octubre de 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.

Latest Communicating Astronomy with the Public journal Highlights Cultural Astronomy
15 de Octubre de 2010: This special issue of Communicating Astronomy with the Public journal (CAPjournal) looks at IYA2009 events that focused on cultural astronomy and discusses how including a historical or cultural aspect can help communicators to engage with a wider audience. During IYA2009, many countries ran projects that can be classed as “Cultural Astronomy”. The activities described focused on indigenous astronomy, the history of astronomy and the inclusive nature of astronomy — as a hobby that can be enjoyed by anyone, anywhere. Activities included public events that combined telescope observing with storytelling, new learning modules for school children, theatre productions and cultural astronomy exhibitions. Articles in this issue include “Australian Aboriginal Astronomy in the IYA2009”, “Mi’kmaq Night Sky Stories”, “Making Astronomy Culturally Relevant” and many more. It is hoped that the selection of events presented in CAPjournal 9 will encourage others to highlight the cultural aspect of astronomy in their own education and ...

Pinning Down an Asteroid Collision
13 de Octubre de 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 de Octubre de 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 ...

Predicting the Size and Shape of an Asteroid at a Distance
7 de Octubre de 2010: Astronomers have used the ESO Very Large Telescope (VLT), in conjunction with other telescopes, adaptive optics technology and an advanced computer program, to accurately predict the size and shape of an asteroid 200 million km from Earth. As the asteroid, (21) Lutetia, is only 100 km across, the challenging Earth-based observations were equivalent to trying to measure the size and shape of a large baked potato at a distance of about 200 km. Each of the approximately 300 snapshots shows the asteroid as little more than a small blob, but by combining all of them, together with further measurements of the brightness of the asteroid over time, the team were able to reconstruct a three-dimensional model of Lutetia. Following this, ESA’s Rosetta spacecraft took high-resolution photographs of Lutetia during a fly-by in July 2010. The images show convincingly that the ground-based observations correctly predicted both the size and shape of the ...

Café & Kosmos 4 October 2010: How Large is the Universe?
30 de Septiembre de 2010: The next Café & Kosmos discussion evening will take place on 4 October 2010. It will deal with the question of the scale of the Universe. We will start with familiar scales: the Sun has a diameter of about 1 million kilometres. But it is only one of about 100 billion stars in our Milky Way, which stretches over a distance of 100 000 light-years. And our home galaxy is just one of many! During the Café & Kosmos evening, astrophysicist Dr. Wolfram Freudling, from ESO, will discuss large-scale structures in the Universe, where galaxies and galaxy clusters cling like drops of dew on a giant, three-dimensional spider’s web. But how can astronomers discover and measure these structures? These and other questions will be answered in the light of frontline scientific research. The Café & Kosmos series of discussions is organised jointly by ESO, the Excellence Cluster Universe and the Max-Planck Institutes for Physics, Astrophysics ...
