6 de Julho de 2010: An international collaboration of astronomers has recently commissioned a new observing mode for the NACO adaptive optics instrument attached to ESO’s Very Large Telescope (VLT) on Paranal. The new capability counteracts the effects of diffraction of light very close to a bright star, enabling astronomers to see very faint nearby objects. The prime example of the kind of objects that can be searched for with the new VLT observing mode, called the Apodising Phase Plate (APP), are Jupiter-like gas giant planets that could be lurking around Sun-like stars in our galaxy. The new mode enables astronomers to search for planets closer to the star than has been previously possible. As a demonstration of the power of the APP technique, a team led by Matthew Kenworthy, Sascha Quanz, and Michael Meyer have confirmed the recent detection of the giant exoplanet around the star Beta Pictoris (eso1024; led by A.-M. Lagrange, Grenoble), ...

30 de Junho de 2010: A breathtaking 3D light show in Linz, Austria gives audiences a virtual tour of the European Extremely Large Telescope (E-ELT), before construction work has even begun in Chile. Lucky viewers can gain a sneak preview of what astronomers can hope to see once the planned observatory is up and running in 2018. The E-ELT will be the world’s biggest optical telescope and will peer deeper into the depths of space than any before it. Audience members at Ars Electronica, a “museum of the future” that focuses on the interplay of technology and art, are even suspended just above the telescope’s colossal 42-metre primary mirror. In reality, this viewpoint will be impossible without risking grave damage to the fragile reflective surface. They are also told of the amazing power of the E-ELT to see smaller and fainter objects than ever before, and how its revolutionary potential could be as great as ...

I hope other schools will be inspired ...

28 de Junho de 2010: One of the movies featured at this year’s Filmfest München, taking place between 25 June and 3 July 2010, is “Nostalgia for the Light” (“Nostalgia de la Luz”). Directed by Patricio Guzmán, the movie is set in Chile, and ESO’s Paranal Observatory is one of the locations featured. Here, at almost 3000 m altitude, astronomers observe the stars with ESO’s Very Large Telescope and make new discoveries about the Universe. Furthermore, in the same area of the Atacama Desert, the environmental conditions preserve human remains, including mummies, explorers, and also those of people who disappeared during the past dictatorial regime. Here, the movie follows a group of women who are digging through the desert soil in search of their disappeared relatives.

10 de Junho de 2010: For the first time, astronomers have been able to directly follow the motion of an exoplanet as it moves from one side of its host star to the other. The planet has the smallest orbit so far of all directly imaged exoplanets, lying almost as close to its parent star as Saturn is to the Sun. Scientists believe that it may have formed in a similar way to the giant planets in the Solar System. Because the star is so young, this discovery proves that gas giant planets can form within discs in only a few million years, a short time in cosmic terms. Together with the press release describing this discovery made with ESO’s Very Large Telescope, ESO has issued a new video podcast, ESOcast 18, entitled “Exoplanet Caught on the Move”, with our host, Dr J. The ESOCast provides a nice explanation of the discovery and its importance, ...
