The Cherenkov Telescope Array (CTA) is the next-generation ground-based instrument designed to detect very high energy gamma rays, with sites in both the southern and northern hemispheres. Gamma rays are electromagnetic radiation of a very high energy, emitted by the hottest and most extreme objects in the Universe — supermassive black holes, supernovae and maybe even remnants of the Big Bang. The material has been edited especially for broadcast use, without commentary or music. More information and download options: http://www.eso.org/public/videos/eso1841b/ Credit: ESO/ P. Horálek

This animation shows the artist’s impression of a vampiric star. The red giant in this system is slowly expelling its outer layers into space. Here the second star in the system, a white dwarf, is siphoning this material into a disc surrounding it. The material then spirals down from this disc onto the white dwarf. Occasionally, more material will fall onto the white dwarf than it can handle. When this occurs, a violent outburst of surplus gas from the white dwarf attempts to correct the imbalance. Channelled by the magnetic field of the star, the ejecta take the form of spectacular symmetric jets extending hundreds of billions of kilometres from the white dwarf’s polar regions.

When a white dwarf in a binary star system acquires more material than it can handle it creates a violent outburst of surplus gas. With this outburst the white dwarf attempts to correct the imbalance. Channelled by the magnetic field of the star, the ejecta take the form of spectacular symmetric jets extending hundreds of billions of kilometres from the white dwarf’s polar regions.

This video shows the evolution of a chaotic and fascinating binary star system named R Aquarii. The time lapse begins with observations from the Nordic Optical Telescope taken in 1997. In the 15 years since that image was taken the system has been observed by many other telescopes, including ESO’s Very Large Telescope. This video lapses between a selection of these images, showing the expansion and evolution of the material surrounding R Aquarii. R Aquarii is a so-called “symbiotic binary”, comprising two stars surrounded by a large, dynamic cloud of gas (a nebula). Systems like this contain two stars in an unequal and complex relationship. R Aquarii is made up of one hot white dwarf and one red giant. The red giant is losing matter to its small companion and occasionally ejecting matter in weird spurts, loops and trails, forming the intriguing shapes seen here. There is a lot going on between the performers in this cosmic double act. The red giant is a variable star, with a brightness that changes by a factor of 750 every year and three weeks. The faint nebula is named Cederblad 211 and is thought to be the result of a violent nova 250 years ago. Also visible is a narrow, vertical, S-shaped feature, with blobs of superheated material.

While testing a new subsystem on the SPHERE planet-hunting instrument on ESO’s Very Large telescope, astronomers were able to capture dramatic details of the turbulent stellar relationship in the binary star R Aquarii with unprecedented clarity — even compared to observations from Hubble.

This animation shows the artist’s impression of a vampiric star. The two stars in this binary system are extremely different: A tiny white dwarf and a gigantic red giant star. The latter is expelling its outer layers into space where the white dwarf is siphoning this material into a disc of material surrounding it. The material then spirals down from this disc onto the white dwarf. More information and download options: http://www.eso.org/public/videos/eso1840d/ Credit: ESO/M. Kornmesser

Already in 1810 astronomers discovered that the brightness of the star R Aquarii periodically changes and it has subsequently been found to vary with a period of approximately a year. During these cycles, R Aquarii has been seen to fade into obscurity and then become so bright as to almost be visible to the naked eye. This animation is an artistic representation of this change in brightness. More information and download options: http://www.eso.org/public/videos/eso1840g/ Credit: ESO/M. Kornmesser

This zoom video starts with a wide view of the Milky Way and ends with a close-up look at the serpentine swirls of dust surrounding a newly-discovered massive binary star system. Nicknamed Apep after an ancient Egyptian deity, it could be the first gamma-ray burst progenitor to be found in our galaxy. The reddish pinwheel shown in this final image of this video is data from the VISIR instrument on ESO’s Very Large Telescope (VLT), and shows the spectacular plumes of dust surrounding Apep. The blue sources at the centre of the image are a triple star system — which consists of a binary star system and a companion single star bound together by gravity. Though only two star-like objects are visible in the image, the lower source is in fact an unresolved binary Wolf-Rayet star. The triple star system was captured by the NACO adaptive optics instrument on the VLT.

ESO’s exquisitely sensitive GRAVITY instrument has added further evidence to the long-standing assumption that a supermassive black hole lurks in the centre of the Milky Way. New observations show clumps of gas swirling around at about 30% of the speed of light on a circular orbit just outside a four million solar mass black hole — the first time material has been observed orbiting close to the point of no return, and the most detailed observations yet of material orbiting this close to a black hole. This visualization uses data from simulations of orbital motions of gas swirling around at about 30% of the speed of light on a circular orbit around the supermassive black hole Sagittarius A*.

This vivid picture of an active star forming region — NGC 2467, otherwise known as the Skull and Crossbones nebula — is as sinister as it is beautiful. This image of dust, gas and bright young stars, gravitationally bound into the form of a grinning skull, was captured with the FORS instrument on ESO’s Very Large Telescope (VLT). Whilst ESO’s telescopes are usually used for the collection of science data, their immense resolving power makes them ideal for capturing images such as this — which are beautiful for their own sake. The video is available in 4K UHD. The ESOcast Light is a series of short videos bringing you the wonders of the Universe in bite-sized pieces.

Deep observations made with the MUSE spectrograph on ESO’s Very Large Telescope have uncovered vast cosmic reservoirs of atomic hydrogen surrounding distant galaxies. The exquisite sensitivity of MUSE allowed for direct observations of dim clouds of hydrogen glowing with Lyman-alpha emission in the early Universe -- revealing that almost the whole night sky is invisibly aglow.

The Sun has shone on our world for four and a half billion years. The light that warms our skin today has been felt by every person who has ever lived. It is our nearest star and our planet’s powerhouse, the source of the energy that drives our winds, our weather and all life. The passage of the Sun’s fiery disc across the sky — day by day, month by month — was the only way to keep track of time for countless past civilisations. Don’t be fooled by the terminology; although it is a typical dwarf star, the Sun consumes 600 million tons of hydrogen each second and is 500 times as massive as all the planets combined. Discover the secrets of our star in this planetarium show and experience never-before-seen images of the Sun’s violent surface in immersive fulldome format. Our team has worked with some of the most talented planetarium producers to bring you this visually striking planetarium show about the most important star in our lives. We encourage the community to produce their own translations and narrations. The script and split audio files are supplied to the right. We welcome receiving copies of the translated scripts and audio files to share with the community. ### Links * Flat trailer * Fulldome trailer * Watch it on the ESO Supernova Planetarium & Visitor Centre * Poster More information and download options: http://www.eso.org/public/videos/The-Sun-show/ Credit: Film Director: Theofanis Matsopoulos Music & Sound Effects: Konstantino Polizois 3D Animation and Graphics: Theofanis Matsopoulos, Luis Calçada & Martin Kornmesser Producer: Theofanis Matsopoulos & the European Southern Observatory (ESO) Executive Producer: Lars Lindberg Christensen Script and Scientific Advice: Lars Lindberg Christensen, Ryan Wyatt, Nicolas Matsopoulos, Adam Hadhazy, Rebecca Davies, Carl Mundy & Paola Amico Narration: Sara Mendes Da Costa Audio mastering: George Deligiannis Japanese Version Translation: Osamu Kato Production: Altair LLC Narration: Namika Matsubara Recording: TAKE'S co.,ltd.
