ESOcast 87: Planet found around closest Star European Southern Observatory (ESO) 2016-08-24 | This is the ESOcast that no viewer will want to miss. We discuss the result of the quest to find a planet around the closest star to the Solar System.The Pale Red Dot campaign aimed to find a planet orbiting our nearest stellar neighbour, Proxima Centauri. Incredibly, the quest succeeded and the team did indeed find a planet. Even more excitingly, the planet, Proxima b, falls within the habitable zone of its host star. The newly discovered Proxima b is by far the closest potential abode for alien life.In this ESOcast, the results of this groundbreaking research are explained in detail, providing insights into the following points: * The extensive verification process the team went through to ensure this result was accurate. * The factors for and against the possibility of life on Proxima b. * The nature of a “habitable zone” around a star.The discovery of Proxima b is a major science result, making this ESOcast a must for those of you curious about one of the most intriguing questions in astronomy — “are we alone?”More information and download options: http://www.eso.org/public/videos/eso1629aSubscribe to ESOcast in iTunes! itunes.apple.com/podcast/esocast-hd/id295471183?mt=2Receive future episodes on YouTube by pressing the Subscribe button above or follow us on Vimeo: vimeo.com/esoastronomyWatch more ESOcast episodes: http://www.eso.org/public/videos/archive/category/esocastFind out how to view and contribute subtitles for the ESOcast in multiple languages, or translate this video on dotSUB: http://www.eso.org/public/outreach/partnerships/translatorsCredit:ESO.Editing: Herbert Zodet.

The NGC 4383 galaxy at different wavelengths European Southern Observatory (ESO) 2024-04-22 | This animation shows the galaxy NGC 4383 in a myriad of colours or wavelengths of light, observed with ESO’s Very Large Telescope. Different elements like hydrogen, oxygen, sulfur or nitrogen emit light at very specific wavelengths, highlighted here as the animation scans through different colours.These data were captured with the Multi Unit Spectroscopic Explorer (MUSE) instrument, which decomposes the light from every location within its field of view into a rainbow or spectrum. When pointed at galaxies such as this one, MUSE allows astronomers to analyse the chemical composition and motion of gas and stars at different locations within the galaxy.More information and download options: eso.org/public/videos/potw2427aCredit: ESO/A.

Zooming into the BH3 black hole system European Southern Observatory (ESO) 2024-04-16 | This video zooms into BH3, the most massive stellar black hole discovered so far in our galaxy. The black hole was detected thanks to the wobbling it induces on a companion star, seen here as a bright point at the centre of the frame towards the end of the zoom. An inset at the end of the video shows an artist’s animation of what the orbits of BH (in red) and its companion star (in blue) around their common centre of mass look like.The various images shown here were taken with different telescopes at different times, and have been blended together to create this zoom. The final animation is an artistic creation.For more details, check: eso.org/public/news/eso2408Credit: ESO/L. Calçada, N. Risinger (skysurvey.org), DSS. Music: Martin Stuertzer
Record-breaking stellar black hole found nearby | ESO News European Southern Observatory (ESO) 2024-04-16 | Astronomers have found the most massive stellar black hole in our galaxy, thanks to the wobbling motion it induces on a companion star. This wobbling was measured over several years with the European Space Agency’s Gaia mission. Additional data from other telescopes, including ESO’s Very Large Telescope in Chile, confirmed that the mass of this black hole, dubbed Gaia BH3, is 33 times that of our Sun. The chemical composition of the companion star suggests that the black hole was formed after the collapse of a massive star with very few heavy elements, or metals, as predicted by theory.

Clash of stars solves stellar mystery | ESO News European Southern Observatory (ESO) 2024-04-12 | Nine years’ worth of data from ESO’s Very Large Telescope Interferometer (VLTI) and other telescopes has revealed the mysterious past of an unusual pair of stars. The study reveals odd differences between these stars for a binary system — one of the stars appears younger and, unlike the other, is magnetic. The pair is also surrounded by a nebula hundreds of times younger than them. Astronomers believe this couple was originally a trio, in which two of the stars were much closer than the third and eventually clashed, violently merging into a younger, magnetic star. This event also released the nebula that now surrounds the stars. This video summarises the discovery.

Zoom in to our black hole seen in a new light European Southern Observatory (ESO) 2024-03-27 | This zoom video takes you to Sagittarius A*, the supermassive black hole at the centre of our galaxy, seen now for the first time in polarised light. The video begins at the Atacama Large Millimeter/submillimeter Array (ALMA), a telescope in which ESO is a partner and that is part of the Event Horizon Telescope (EHT). As we zoom into the heart of our galaxy, we switch from visible to infrared light to peer through the dense clouds of dust in this region. We see some stars orbiting very close to Sgr A*, observed with ESO’s Very Large Telescope Interferometer. Finally, we arrive at Sgr A*. The first image of this black hole was released in 2022. The swirling lines overlaid in this new image mark the orientation of polarisation, which is linked to the shape of the magnetic field around the black hole.The various observations used here were taken at different times, by different teams and with different facilities, and put together for the purpose of the zoom effect. The images go from visible wavelengths at the beginning to infrared, with the very final image being taken at radio wavelengths.For more details, check the corresponding release: eso.org/public/videos/eso2406bCredits: ESO/L.

A polarised view of our black hole | ESO News European Southern Observatory (ESO) 2024-03-27 | A new image from the Event Horizon Telescope (EHT) collaboration has uncovered strong and organised magnetic fields spiraling from the edge of the supermassive black hole Sagittarius A* (Sgr A*). Seen in polarised light for the first time, this new view of the monster lurking at the heart of the Milky Way galaxy has revealed a magnetic field structure strikingly similar to that of the black hole at the centre of the M87 galaxy, suggesting that strong magnetic fields may be common to all black holes. This similarity also hints toward a hidden jet in Sgr A*.

Mirror segments get shiny | ELT Updates European Southern Observatory (ESO) 2024-03-14 | The first of the ESO’s Extremely Large Telescope (ELT)’s primary mirror segments have been given a shiny new coating. Each 1.5 metre segment is coated with just 1.7 grams of highly reflective silver, as well as adhesive and protective layers. Precise sensors are installed to detect misalignments on a nanometer scale once the telescope is fully built. Out of the 798 total segments that will be used to form the telescope, two will be recoated every day to ensure every segment maintains the best reflectivity.For more details, check the corresponding announcement: eso.org/public/announcements/ann24005Credits: ESODirected by: Angelos Tsaousis Editing: Angelos TsaousisWeb and technical support: Gurvan Bazin and Raquel Yumi Shida Written by: Bárbara FerreiraFootage and photos: ESO, L.

Survey reveals secrets of planet birth around dozens of stars | ESOcast Light European Southern Observatory (ESO) 2024-03-05 | In a series of studies, a team of astronomers has shed new light on the fascinating and complex process of planet formation. The stunning images, captured using the European Southern Observatory's Very Large Telescope (ESO’s VLT) in Chile, represent one of the largest ever surveys of planet-forming discs. The research brings together observations of more than 80 young stars that might have planets forming around them, providing astronomers with a wealth of data and unique insights into how planets arise in different regions of our galaxy. This video summarises the discovery.

Dance of the cranes | ELT Updates European Southern Observatory (ESO) 2024-03-04 | A watched pot never boils, but luckily that doesn’t apply to us watching ESO’s Extremely Large Telescope (ELT) being constructed. This Picture of the Week shows a timelapse overlooking Cerro Armazones in the Chilean Atacama Desert over the course of 2023, as the dome of the ELT is pieced together in smooth choreography. Partly built at a nearby base camp, large steel elements arrive at the peak ready to be neatly assembled together into the dome. The steel structure provides the skeleton around which a protective insulated cladding is now being applied. It rests on a concrete foundation separated from the central pier where the telescope will be, to reduce vibrations propagating through the ground. The dome can rotate on 36 trolleys allowing the telescope to observe the whole sky. A new webcam inside the dome shows progress in the azimuth structure that will support the telescope, as well as the two huge platforms that will hold the ELT’s scientific instruments.In this timelapse, each frame was captured at the same time every day; the Sun’s apparent position on the sky changes with seasons as the Earth orbits around the Sun. This webcam view provides an incredible peek at the ELT construction progress, and we cannot wait to see the wonders its 39-metre eye will discover.Credit: ESOMore information and download options: eso.org/public/videos/potw2410a

New link found between water and planet formation | ESOcast Light European Southern Observatory (ESO) 2024-02-29 | Researchers have found water vapour in the disc around a young star exactly where planets may be forming. Water is a key ingredient for life on Earth, and is also thought to play a significant role in planet formation. Yet, until now, we had never been able to map how water is distributed in a stable, cool disc — the type of disc that offers the most favourable conditions for planets to form around stars. The new findings were made possible thanks to the Atacama Large Millimeter/submillimeter Array (ALMA), in which the European Southern Observatory (ESO) is a partner. This video summarises the discovery.

Metal scar found on cannibal star | ESOcast Light European Southern Observatory (ESO) 2024-02-26 | Using ESO’s Very Large Telescope, astronomers have found a metal ‘scar’ imprinted on the surface of a dead star. This video summarises the discovery.When a star like our Sun reaches the end of its life, it can ingest the surrounding planets and asteroids that were born with it. That seems to be the case of the white dwarf WD 0816-310, the Earth-sized remnant of a star similar to, but somewhat larger than, our Sun.The scar the team observed is a concentration of metals imprinted on its surface. These metals seem to originate from a planetary fragment as large as or possibly larger than Vesta, which is about 500 kilometres across and the second-largest asteroid in the Solar System.This video summarises the discovery.

Have you seen such trails? #shorts European Southern Observatory (ESO) 2024-02-22 | If you have seen such trails of lights sweeping the night sky, you should know that they are neither UFOs, nor shooting stars. They are satellites in low Earth orbit. 🛰️There are over 8,000 satellites in this orbit already — and due to the light they reflect, they hinder the view and exploration of the night sky from the ground. So, astronomers have taken action to mitigate this threat. For example, ESO and other astronomical organisations have petitioned the UN to safeguard the night sky by advocating for dimmer satellites. These initiatives have yielded positive results already, with many space companies painting their satellites darker, so that they become less reflective.Learn more in this episode of #ChasingStarlight : youtube.com/watch?v=Lvw8J4nwpC0

Why cant you see the stars? #shorts European Southern Observatory (ESO) 2024-02-16 | If you reside in a city, chances are you're only able to see a handful of stars in the night sky. But as soon as you go to the countryside or more remote areas like mountains, suddenly there are more stars visible. Why is that?We are able to see a few thousands stars from Earth with our very own eyes. However, our capacity is impaired by light pollution and its degree of severity depending on where we are.If we could limit unnecessary artificial light in cities, we might be able to bring back at least part of the starry night sky we enjoy in remote areas.As ESO astronomer Suzanna Randall points out, limiting light pollution would be beneficial far beyond the beauty of the stars. It could improve our health and that of animals, as well as reduce waste of energy and money.Learn more about the issue of light pollution with this episode of #ChasingStarlight : youtube.com/watch?v=Lvw8J4nwpC0How is the sky in your area?

ELT dome moves for the first time | ELT Updates European Southern Observatory (ESO) 2024-01-29 | Like a flower following the Sun, the dome of ESO’s Extremely Large Telescope (ELT) will be able to rotate to allow the telescope to track objects in the sky. Seen under the bright blue skies of Cerro Armazones in the Chilean Atacama Desert, this video shows a test of the dome rotating for the first time.The test moved the dome 10 m in either direction at 1 cm/s, but the final operating speed will be a walking pace of 5 km/h. The test was performed by engineers of Cimolai, the company contracted by ESO to design and build the ELT dome and telescope structure. The humans hard at work in this sped-up video show, for scale, the sheer size of the telescope dome. Rotating the dome is no small feat, as its skeleton currently weighs about 2500 tons, and will eventually weigh around 6100 tons when finished. This first test was carried out “manually” with special hydraulic devices, but eventually the enclosure will rotate via motorised bogies. While the motion of the dome is designed to be smooth, and was found to be during this test, the dome stands separate from the rest of the structure in order to limit vibrations to the telescope itself.The dome, in its final form, will have an insulated aluminum cladding to protect the telescope from the elements and sliding doors to open it to the stars. Building this marvel of engineering in the middle of the desert presents unique challenges, and yet, recent achievements such as the dome rotating and the first mirror segments stored at Paranal show the ELT is moving closer to becoming reality.

Can stars kiss? #shorts European Southern Observatory (ESO) 2024-01-25 | It seems they can, and the VFTS 352 system discovered with our Very Large Telescope (VLT) is one such example. Such systems are known as over-contact binaries, and VFTS 352 is the hottest and largest of them all. 😲 Its mass is around 57 times that of the Sun, and with a surface temperature of about 40,000 degrees Celsius (more than six times hotter than the Sun's surface 🥵), this relationship is certainly steaming!

One of our most anticipated deliveries! | ELT Updates European Southern Observatory (ESO) 2024-01-22 | After a journey of more than 10,000 km by sea and by land, the first 18 segments of the main mirror of ESO's Extremely Large Telescope (ELT) have arrived at our Paranal Observatory in Chile from Europe. With the segments at Paranal, the next phase in this intricate process involves the coating of the mirror segments in the ELT Technical Facility to give them their highly reflective finish — a process that will be reiterated on each segment every 18 months once the ELT begins observations.Read more about this milestone here: eso.org/public/images/potw2404a and here: eso.org/public/announcements/ann24001Credit:ESO.

ELT main mirror segments shipped to Chile | ELT Updates European Southern Observatory (ESO) 2023-12-18 | The first 18 segments of the main mirror (M1) of ESO’s Extremely Large Telescope (ELT) have been delivered to ESO and shipped to Chile. Once they arrive, the segments will be transported to the ELT Technical Facility, at ESO’s Paranal Observatory in the country’s Atacama Desert, where they will be coated in preparation for their future installation on the telescope main structure. Unable to be physically made in one piece, M1 will consist of 798 individual segments arranged in a large hexagonal pattern, with an additional 133 being produced to facilitate the recoating of segments. With a diameter of more than 39 metres, it will be the largest telescope mirror in the world.More information and download options: eso.org/public/videos/eso2319aCredit: ESODirected by: Angelos Tsaousis Editing: Angelos TsaousisWeb and technical support: Gurvan Bazin and Raquel Yumi Shida Written by: Bárbara FerreiraConsultants: Roberto Tamai, Michele CirasuoloFootage and photos: ESO, Luis Calçada, Martin Kornmesser, Herve Kurlandczyck, Andreia Centeio, PH.

Zooming into the HH 1177 young star European Southern Observatory (ESO) 2023-12-06 | This video starts with a wide view of the Milky Way, zooming into the Large Magellanic Cloud 160 000 light-years away, all the way to the young star system HH 1177 within it. With the Multi Unit Spectroscopic Explorer (MUSE) instrument on ESO’s Very Large Telescope, astronomers found a jet system coming from a young, massive star. Using the Atacama Large Millimeter/submillimeter Array (ALMA), in which ESO is a partner, a rotating disc was also discovered — a first outside our own galaxy. An artist’s impression, at the end, reveals the system according to these observations.For more details, check: eso.org/public/news/eso2318More information and download options: eso.org/public/videos/eso2318cCredit: ESO
