 ESOcast 40: When Speed Matters — Discovery of the Accelerating Universe Wins 2011 Nobel Prize for Physics | File Type: video/x-m4v | Duration: 420

In the past two decades, astronomers have made a truly revolutionary discovery: that the cosmos is not only expanding, but is doing so at an ever-faster rate. The discovery of the accelerated expansion of the Universe was awarded the 2011 Nobel Prize in Physics.

 ESOcast 39: A Black Hole’s Dinner is Fast Approaching | File Type: video/x-m4v | Duration: 317

Astronomers using ESO's Very Large Telescope have discovered a gas cloud with several times the mass of the Earth accelerating towards the black hole at the centre of the Milky Way. This is the first time ever that the approach of such a doomed cloud to a supermassive black hole has been observed. This ESOcast explains the new results and includes spectacular simulations of how the cloud will break up over the next few years.

 ESOcast 38: Faraway Eris is Pluto’s twin | File Type: video/x-m4v | Duration: 308

This ESOcast describes how astronomers have accurately measured the diameter of the faraway dwarf planet Eris for the first time by catching it as it passed in front of a faint star. This event was seen at the end of 2010 by telescopes in Chile, including the TRAPPIST telescope at ESO’s La Silla Observatory. The observations show that Eris is an almost perfect twin of Pluto in size. Eris seems to have a very reflective surface, suggesting that it is covered in ice, probably a frozen atmosphere.

 ESOcast 37: Full-size Mock-up of World's Largest Telescope Mirror Built at ESO's Open House Day | File Type: video/x-m4v | Duration: 246

On Saturday 15 October 2011 ESO opened the doors of its headquarters in Garching bei München, Germany, to the public. Throughout the day, thousands of visitors had the chance to help build a full-size mock-up mirror of the European Extremely Large Telescope (E-ELT) -- the largest planned telescope in the world -- and to experience many other aspects of ESO's work.

 ESOcast 36: ALMA Opens Its Eyes | File Type: video/x-m4v | Duration: 568

The most complex ground-based astronomy observatory in the world, the Atacama Large Millimeter/submillimeter Array (ALMA), has officially opened for astronomers. The first released image, from a telescope still under construction, reveals a view of the Universe that cannot be seen at all by visible-light and infrared telescopes.

 ESOcast 35: Fifty New Exoplanets | File Type: video/x-m4v | Duration: 264

Astronomers using ESO’s leading exoplanet hunter HARPS have today announced more than fifty newly discovered planets around other stars. Among these are many rocky planets not much heavier than the Earth. One of them in particular seems to orbit in the habitable zone around its star. This ESOcast we look at how astronomers discover these distant worlds and what the future may hold for finding rocky worlds like the Earth that may support life.

 ESOcast 34: How To Stop a Star's Twinkle - The astronomy podcast exploring the cosmic frontier with Dr J | File Type: video/x-m4v | Duration: 530

We have all looked up at the sky at night and seen the stars twinkle. It may be pretty and romantic, but it is also a big problem for astronomers, as the shimmering starlight blurs observations.

 ESOcast 33: Under Chilean Skies | File Type: video/x-m4v | Duration: 464

In the pursuit of pristine skies, ESO, the European Southern Observatory, operates its telescopes far beyond Europe, in the remote and arid landscape of the Atacama Desert in Chile. Check why in this ESOcast episode.

 ESOcast 32: Most Distant Quasar Found | File Type: video/x-m4v | Duration: 290

This ESOcast is about the discovery of the most distant quasar found to date. This brilliant beacon is powered by a black hole with a mass two billion times that of the Sun. It is by far the brightest object yet discovered in the early Universe.

 ESOcast 31: Pandora's Cluster | File Type: video/x-m4v | Duration: 309

This joint episode of the Hubblecast and ESOcast presents Abell 2744, an unusual cluster of galaxies nicknamed "Pandora's Cluster" by the astronomers who have studied it. Looking at the galaxies, gas and dark matter in the cluster, scientists have reconstructed the series of huge collisions that created it, and have uncovered some strange phenomena never seen together before.
