    from ESO Observatory Added 5,955 15 0

    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. More information: http://www.eso.org/public/videos/eso1122a/

    • ESOcast 46: Catching Light -- Special 50th anniversary episode #6


      from ESO Observatory Added 541 4 0

      ESOcast 46 is the sixth special episode of this series. It describes how state-of-the-art cameras and spectrographs help ESO’s powerful telescopes collect and analyse the faint light from the distant Universe. Without these instruments, ESO’s eyes on the sky would be blind. Today’s astronomical images are very different from those from the 1960s. Back then, astronomers used large photographic glass plates, which were not very sensitive and hard to handle. Nowadays, ESO’s telescopes use some of the largest and most sensitive electronic detectors in the world. They catch almost every cosmic photon and recover almost every possible bit of information. For instance, the VLT Survey Telescope’s camera — OmegaCAM — has 32 detectors, which team up to produce spectacular images of the Universe, each with an impressive 268 million pixels. But astronomy is not only about taking breathtaking images. Astronomers are always after as much information as possible so they need to dissect the starlight into its component colours to study its composition. Spectroscopy is one of the most powerful tools in astronomy and ESO’s telescopes also have some of the world’s most powerful spectrographs, such as the powerful X-shooter at the Very Large Telescope. Spectroscopy allows astronomers to infer important properties of the stars, such as the chemical elements they contain, their temperatures, motions, and even their ages. Moreover, they can study the atmospheres of exoplanets orbiting distant stars or newborn galaxies at the edge of observable Universe. Watch this episode to discover more about ESO’s state-of-the-art astronomical instruments.

        Leading up to ESO's 50th anniversary in October 2012, we are releasing eight special ESOcasts, each a chapter from the movie Europe to the Stars -- ESO's First 50 Years of Exploring the Southern Sky. This first special episode — entitled “Going South” — describes the birth of ESO, and in particular why astronomers from European countries decided to explore the southern sky by placing an astronomical observatory in Chile.

          from ESO Observatory Added 460 3 0

          Astronomers using ESO instruments have discovered a remarkable extrasolar planetary system that has some striking similarities to our own Solar System. At least five planets are orbiting the Sun-like star HD 10180, and the regular pattern of their orbits is similar to that observed for our neighbouring planets. One of the new extrasolar worlds could be only 1.4 times the mass of the Earth, making it the least massive exoplanet ever found. This video podcast explains how these faraway planets were detected and exactly what we know about them.

            In this second episode of the ESOcast Dr. J takes us to the centre of the Milky Way to talk about a supermassive black hole there located. We will hear from two scientists involved in an unprecedented 16-year long study, which used several of ESO’s flagship telescopes to produce the most detailed view ever of the surroundings of the monster lurking at our Galaxy’s heart. How were the hidden secrets of this tumultuous region unravelled? Watch this ESOcast and find out. To find out more about this video, please visit: http://www.eso.org/public/videos/eso0846a/

              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.

                This is the third installment of Chile Chill, a type of ESOcast designed to offer a calm experience of the Chilean night sky and ESO's observing sites, undisturbed by facts or narration. In this episode we are treated to stunning views of the Atacama Desert, including the conical volcano Licancabur and slow moonrises over the Andes.

                  The Sun sets behind Cerro Paranal in the Chilean Atacama desert. While astronomers get ready to observe with ESO's Very Large Telescope, Nature prepares for her own grand display. As night falls over the desert, the southern sky reveals its nocturnal beauty, leaving the spectator in silent amazement. Some people, however, don’t just stare at the spectacle. With great skill, they record these unique moments for everyone to see - they are the photographers of the night.

                  • ESOcast 62: Three planets found in star cluster


                    from ESO Observatory Added 273 3 0

                    In this ESOcast we look at how astronomers have used ESO's HARPS planet hunter in Chile, along with other telescopes around the world, to discover three planets orbiting stars in the cluster Messier 67. Although more than one thousand planets outside the Solar System are now confirmed, only a handful have been found in star clusters. Remarkably one of these new exoplanets is orbiting a star that is a rare solar twin — a star that is almost identical to the Sun in all respects.

                      A European team of astronomers using ESO’s Very Large Telescope (VLT) has measured the distance to the most remote galaxy so far. By carefully analysing the very faint glow of the galaxy they have found that they are seeing it when the Universe was only about 600 million years old (a redshift of 8.6). These are the first confirmed observations of a galaxy whose light is clearing the opaque hydrogen fog that filled the cosmos at this early time. Credit: ESO.
