ESOcast 124: Q&A met Tim de Zeeuw, ESO's vertrekkend directeur-generaal (Engels)

24 augustus 2017: In ESOcast 124 blikt ESO’s vertrekkend directeur-generaal Tim de Zeeuw terug op zijn tien jaar bij ESO. De afgelopen tien jaar verstevigde ESO zijn positie als 's werelds belangrijkste intergouvernementele astronomieorganisatie. In deze periode van groei traden twee lidstaten toe en werden nieuwe telescopen, instrumenten en faciliteiten gebouwd die tot opmerkelijke ontdekkingen leiden of zullen leiden. Als directeur-generaal speelde Tim de Zeeuw een belangrijke rol in de evolutie van ESO en de nieuwe terreinen de organisatie betreedt. De belangrijkste ontwikkeling onder zijn leiderschap is wellicht dat de ESO Council instemde met de bouw van de Extremely Large Telescope. Die telescoop zal een nieuw tijdperk in de sterrenkunde inleiden. Abonneren op de ESOcasts kan op iTunes, YouTube of Vimeo. Veel andere ESOcast afleveringen zijn ook beschikbaar.

ESPRESSO Planet Hunter Heads for Chile

22 augustus 2017: ESPRESSO — the Echelle SPectrograph for Rocky Exoplanet and Stable Spectroscopic Observations — has passed ESO’s Preliminary Acceptance Europe (PAE). This means that it has successfully completed all preliminary testing, and the instrument will now be packed up and shipped to Chile, where it will be installed at the combined coudé focus of the Very Large Telescope (VLT). ESPRESSO is expected to see first light later in 2017. ESPRESSO, an echelle spectrograph, is one of the most eagerly awaited instruments in the astronomical world [1]. It is the successor to ESO’s planet-hunting HARPS instrument on the ESO 3.6-metre telescope at La Silla, and will exceed HARPS’s precision by about 10 times [2]. As the next-generation planet hunter, ESPRESSO will measure minuscule changes in the light from stars, as planets — many of them smaller than Neptune — rotate around them. This radial velocity method, as it is known, records tiny ...

A Very Close Encounter

10 augustus 2017: Back in October 2012, the near-Earth asteroid 2012 TC4 had a close encounter with Earth. It passed our planet at a distance only a quarter of that between the Earth and the Moon. In October 2017, this small asteroid, with a size of only about 15 to 30 metres, will return for another very close fly-by, making it the perfect object to test the asteroid detection and tracking network. As 2012 TC4 could not be observed for several years, its orbit was not very well known. In particular, astronomers could not yet predict just how close it will come to Earth during its next fly-by in 2017. So finding it again and observing it in detail are crucial to learning more about how close it will get to Earth and refining our understanding of the path it will take. Because the asteroid is so small and is still far away ...

Aanwijzing voor relativistische effecten bij sterren die rond het superzware zwarte gat in het centrum van de Melkweg bewegen

9 augustus 2017: Een nieuwe analyse van gegevens van ESO’s Very Large Telescope en andere telescopen wijst er voor het eerst op dat de omloopbanen van sterren rond het superzware zwarte gat in het centrum van de Melkweg de subtiele effecten kunnen vertonen zoals die zijn voorspeld door Einsteins algemene relativiteitstheorie. Er zijn aanwijzingen dat de omloopbaan van de ster S2 enigszins afwijkt van het pad dat met behulp van klassieke fysica is berekend. Dit spannende resultaat is een voorproefje van de veel nauwkeurigere metingen en tests die in 2018 met het GRAVITY-instrument zullen worden gedaan wanneer S2 heel dicht langs het zwarte gat beweegt. In het centrum van de Melkweg, ruim 26.000 lichtjaar van de aarde, bevindt zich het meest nabije superzware zwarte gat, dat vier miljoen keer zoveel massa heeft als de zon. Dit monster is omringd door een klein groepje sterren dat met hoge snelheid om hem heen draait. Het ...

ESOcast 120: Chile Chill 10: VLT Main Mirror Recoating

7 augustus 2017: This video takes a relaxed look at a tense process — cleaning and recoating the surface of one of the ESO Very Large Telescope’s 8.2-metre main mirrors. Every night the huge mirrors are exposed to the atmosphere whilst uncovered during observing sessions. They gradually accumulate dust and other pollutants that reduce their reflectivity, making them less effective at capturing faint light from the cosmos. So they are regularly removed from the telescope, taken down the mountain to the recoating facility, cleaned and finally recoated with a thin and highly reflective new aluminium layer.

Chilean Minister of Energy Sees Paranal Connect to National Electricity Grid

4 augustus 2017: The Chilean Minister of Energy, Andrés Rebolledo, recently attended a ceremony marking the connection of ESO’s Paranal and Armazones sites, the latter being where the Extremely Large Telescope (ELT) will be located, to the Chilean national electricity grid. The new electricity supply will reduce costs and reduce the observatory’s carbon footprint. Minister Rebolledo remarked on the importance of this development as an example of the capability of Chile’s electricity network and its ability to provide a safe, high-quality supply of energy for cutting-edge astronomical research. Roberto Tamai, the ELT Programme Manager, who was the Project Manager for this ESO upgrade, thanked the Chilean government and institutions for helping to create the energy infrastructure that will underpin progress on the ELT site. With its 39-metre main mirror the construction of the ELT is a demanding technological and engineering challenge. Tamai stressed that the electricity supply is a key part of the ...

ESOcast 119: AOF First Light

2 augustus 2017: Light is the lifeblood of astronomy and by collecting it using telescopes and instruments astronomers can study almost everything in space. Atmospheric turbulence, however, distorts the light arriving at telescopes on Earth. At ESO’s Very Large Telescope, researchers are meeting this challenge with the revolutionary new Adaptive Optics Facility (AOF) helping the MUSE instrument to break new records. ESOcast 119 explores why adaptive optics is necessary for research at ESO, how the new AOF will improve the capabilities of ESO’s MUSE instrument, and the future of adaptive optics on instruments at ESO’s Very Large Telescope.

ESO and ESA Reach Agreement to Site Test-Bed Telescope at La Silla

7 juli 2017: In August 2015, ESO and the European Space Agency (ESA) signed a cooperation agreement setting the terms and conditions for mutual cooperation and the exchange of scientific research information between the two organisations. The first project to be implemented under this cooperation agreement is the deployment of a Test-Bed Telescope at ESO’s La Silla Observatory in northern Chile. Operating alongside a similar project in the northern hemisphere, the 56-cm Test-Bed Telescope (TBT) will act as a precursor to a full autonomous optical sensor network which will detect and track an extensive list of near-Earth objects, such as asteroids. The TBT will demonstrate the instrument’s hardware and software capabilities, such as automatic scheduling, remote real-time control, and autonomous data processing.

ESOcast 116: OPC 100

7 juli 2017: To astronomers, ESO’s state-of-the-art telescopes are not just about collecting pretty pictures, however alluring they may be; they are tools to collect data, through which remarkable discoveries are made. But there is simply not enough observing time available for everyone to observe to their heart’s content — so how is telescope time allocated? ESOcast 116 explores how astronomers request time to use an ESO telescope, and how ESO’s Observing Programmes Committee, embarking on its one-hundredth meeting, examines and judges these proposals in order to ensure that ESO is making the best use of its telescopes to advance our knowledge and understanding of the Universe.

ESO’s SPHERE ontdekt een unieke exoplaneet

6 juli 2017: Een van de meest uitdagende en opwindende terreinen van de moderne astronomie is de jacht op exoplaneten – andere werelden die om andere sterren draaien. Onlangs is met het Spectro-Polarimetric High-contrast Exoplanet REsearch instrument – kortweg SPHERE – van ESO’s Very Large Telescope (VLT) een nieuwe exoplaneet opgespoord: HIP 65426b. Deze planeet, die ongeveer 385 lichtjaar van ons verwijderd is, is de eerste die SPHERE heeft ontdekt [1] – en het blijkt om een bijzonder interessant exemplaar te gaan. Met een temperatuur van 1000 tot 1400 graden Celsius is de planeet, die zes tot twaalf keer zoveel massa heeft als Jupiter, behoorlijk warm. Hij lijkt te zijn gehuld in een zeer stoffige atmosfeer met dikke bewolking, en draait om een hete, jonge ster die verrassend snel om zijn as wentelt. De ster lijkt niet te zijn omringd door een schijf van puin, wat merkwaardig is voor zijn leeftijd. Het ontbreken ...
