Com observações feitas pela primeira vez em luz polarizada, a nova imagem do monstro que se esconde no coração da Via Láctea revelou um campo magnético com uma estrutura muito semelhante à do buraco negro situado no centro da galáxia M87, sugerindo que campos magnéticos intensos podem ser comuns a todos os buracos negros. Esta semelhança aponta também para a existência de um jato oculto em Sgr A*. Os resultados foram publicados hoje na revista da especialidade The Astrophysical Journal Letters. Em 2022, os cientistas revelaram a primeira imagem de Sgr A* durante conferências de imprensa em todo o mundo, incluindo no Observatório Europeu do Sul (ESO). Embora o buraco negro supermassivo da Via Láctea, que se encontra a cerca de 27 000 anos-luz de distância da Terra, seja pelo menos mil vezes mais pequeno e menos massivo do que o de M87, o primeiro buraco negro a ser fotografado, as observações revelaram que os dois têm um aspeto bastante semelhante, o que levou os cientistas a perguntarem-se se estes buracos negros partilhariam características comuns para além da sua aparência. Para o descobrir, a equipa decidiu estudar o Sgr A* em luz polarizada. Estudos anteriores da luz em torno do buraco negro de M87 (M87*) revelaram que os campos magnéticos à sua volta permitiam que o buraco negro lançasse poderosos jatos de material para o seu meio circundante. Com base neste trabalho, as novas imagens revelaram agora que o mesmo pode ser verdade para Sgr A*. FONTE: https://www.eso.org/public/portugal/news/eso2406/?lang #BLACKHOLE #UNIVERSE #EHT

Scientists have released a more detailed version of the first image of a black hole. That first image, released four years ago, showed a blurry, round-shaped orange object. Now, researchers have used machine learning methods to create an improved picture. The new image was recently published in the Astrophysical Journal Letters. The same shape remains as in the first image, but it has a narrower ring and sharper resolution. Scientists have said the black hole in the image sits at the center of a galaxy called M87, more than 53 million light-years from Earth. A light year is the distance light travels in a year --- about 9.5 trillion kilometers. The mass of the black hole is 6.5 billion times greater than that of Earth's sun.科学家们发布了第一张黑洞图像的更详细版本。四年前发布的第一张图片显示了一个模糊的圆形橙色物体。现在，研究人员已经使用机器学习方法来创建改进的图片。这张新图片最近发表在《天体物理学杂志快报》上。与第一张图片中的形状相同，但它的环更窄，分辨率更清晰。科学家们表示，图像中的黑洞位于一个名为 M87 的星系中心，距离地球超过 5300 万光年。一光年是光在一年内传播的距离——大约 9.5 万亿公里。黑洞的质量是地球太阳的 65 亿倍。A network of radio telescopes around the world gathered the data used to make the image. But even with many telescopes working together, holes remained in the data. In the latest study, scientists depended on the same data, but used machine learning methods to fill in the missing information. The resulting picture looks similar to the image, but with a thinner “doughnut” and a darker center, the researchers said. “For me, it feels like we're really seeing it for the first time,” said the lead writer of the study, Lia Medeiros. She is an astrophysicist at the Institute for Advanced Study in New Jersey. She said it was the first time the team had used machine learning to fill in the data holes.世界各地的射电望远镜网络收集了用于制作图像的数据。但即使有许多望远镜一起工作，数据中仍然存在漏洞。在最新的研究中，科学家们依赖于相同的数据，但使用机器学习方法来填补缺失的信息。研究人员说，由此产生的图片看起来与图像相似，但“甜甜圈”更薄，中心更暗。 “对我来说，感觉就像我们第一次真正看到它，”该研究的主要作者 Lia Medeiros 说。她是新泽西高等研究院的天体物理学家。她说，这是该团队第一次使用机器学习来填补数据漏洞。With a clearer picture, researchers hope to learn more about the black hole's properties and gravity in future studies. Medeiros said the team also plans to use machine learning on other images of space objects. This could include the black hole at the center of our galaxy, the Milky Way. The study's four writers are members of the Event Horizon Telescope (EHT) project. It is an international effort begun in 2012 with the goal of directly observing a black hole's nearby environment. A black hole's event horizon is the point beyond which anything - stars, planets, gas, dust and all forms of electromagnetic radiation – can escape. Dimitrios Psaltis is an astrophysicist at Georgia Institute of Technology in Atlanta, Georgia. He told Reuters news agency the main reason the first image had many gaps is because of where the observing telescopes sit. The telescopes operate from the tops of mountains and “are few and far apart from each other,” Psaltis said.有了更清晰的图像，研究人员希望在未来的研究中更多地了解黑洞的特性和引力。 Medeiros 说，该团队还计划在其他空间物体图像上使用机器学习。这可能包括我们银河系中心的黑洞，即银河系。该研究的四位作者是事件视界望远镜 (EHT) 项目的成员。这是 2012 年开始的一项国际努力，目标是直接观察黑洞附近的环境。黑洞的事件视界是任何东西——恒星、行星、气体、尘埃和所有形式的电磁辐射——都可以逃逸的点。 Dimitrios Psaltis 是佐治亚州亚特兰大市佐治亚理工学院的天体物理学家。他告诉路透社，第一张图片有很多空隙的主要原因是观测望远镜所在的位置。 Psaltis 说，这些望远镜在山顶上运行，“数量很少，而且彼此之间距离很远”。As a result, the telescope system has a lot of 'holes' and scientists can now use machine learning methods to fill in those gaps, he added. "The image we report in the new paper is the most accurate representation of the black hole image that we can obtain with our globe-wide telescope," Psaltis said.因此，望远镜系统有很多“漏洞”，科学家现在可以使用机器学习方法来填补这些空白，他补充说。 Psaltis 说：“我们在新论文中报道的图像是我们用全球望远镜可以获得的最准确的黑洞图像。”

Black holes are the strangest objects in the universe. Astronomers have known for some time about the existence of a supermassive black hole at the center of our own galaxy, the Milky Way. They called it Sagittarius A* or Sgr A*. Just recently, using the Event Horizon Telescope (EHT), astronomers for the first imaged the light right outside the event horizon of this black hole. A few years ago, EHT also imaged the central black hole in the galaxy M87. Please join astrophysicist Salman Hameed is exploring how this was done and why it was more difficult to "see" our own black hole in the Milky Way compared to the one in M87, 55 million light years away.For video of this podcast: https://youtu.be/ovYiGH3cqmI

Čierne diery boli jednou z predpovedí všeobecnej teórie relativity, no ani samotný Albert Einstein neveril v ich existenciu. Po viac ako sto rokoch od vzniku teórie sme sa dočkali priamého pozorovania. Prvá snímka supermasívnej čiernej diery M87* z galaxie Messier 87 bola zverejnená v roku 2019. Tento rok, 12.5.2022, bola odhalená ďalšia fotografia čiernej diery, ktorá nesie názov Sagittarius A*, tentokrát zo stredu našej galaxie. Oba obrázky vznikli vďaka medzinárodnému projektu Event Horizon Telescope (EHT), ktorý sa zameriava na sledovanie čiernych dier prostredníctvom siete rádioteleskopov. Ako možno pozorovať čiernu dieru? Odlišujú sa od seba doteraz pozorované čierne diery? A vôbec, čo nám to hovorí o našom vesmíre? Erráta: v čase 7:20 hovoríme o zverejnení prvého pozorovania gravitačných vĺn v roku 2017, správne má byť : pozorované v roku 2015, zverejnené 2016. ___ Zvukový šumový predel pred záverom je "sonifikáciou" obrazu čiernej diery Sgr A* , zdroj a viac info tu: https://chandra.si.edu/photo/2022/sgra/animations.html (6. 6. 2022) AD HOC je séria podcastov, v ktorých vám budú Alenka a Peter (ne)pravidelne prinášať novinky zo sveta vedy, vesmíru a vôbec.

Em 2019 não só meio acadêmico, mas o mundo inteiro, ficou fascinado com a primeira imagem de um buraco negro, M87, obtida pela colaboração Event Horizon Telescope (EHT) integrando dados interferométricos, sinais de rádio coletados por oito radiotelescópios que cobriam quase todo o planeta: o processamento e análise bem sucedida de uma quantidade descomunal de informações nos mostraram, pela primeira vez, que "cara" tem (em rádio), um buraco negro supermassivo. Há poucos dias atrás, em 12 de maio de 2022, a equipe do EHT anunciou seu segundo feito, que foi imagear Sagittarius A* (Sgt A*), que ocupa o centro de nossa galáxia - a Via Láctea, superando novas dificuldades técnicas, muito mais complexas que as anteriores. Neste episódio, voltamos a conversar com a colega Thaisa Storchi Bergmann do Departamento de Astronomia do IF-UFRGS, especialista reconhecida internacionalmente neste tema, e avaliamos as primeiras impressões acerca desse fascinante feito tecnológico e científico. As imagens que vemos representam uma grande transformação, não só inaugurando uma nova era do estudo desses insólitos objetos astronômicos, como confirmando diversas predições astrofísicas acumuladas durante um século, e vindicando, mais uma vez, os acertos da Teoria da Relatividade Geral de Einstein. Pelo menos cientificamente, estamos a viver tempos maravilhosos. Produção e edição: Jorge Quillfeldt Créditos da Imagem: ESO/Jose Francisco Salgado (josefrancisco.org), EHT Collaboration

Nesta quinta-feira, o mundo viu pela primeira vez imagens do Sagittarius A*, que fica no centro da Via Láctea, a galáxia do Sistema Solar. A conquista é do Event Horizon Telescope (EHT), iniciativa da qual participam centenas de cientistas de mais de uma dezena de instituições. A partir de 8 pontos da Terra eles "observam ao mesmo tempo o mesmo alvo e depois combinam todos os sinais”, em um “desafio tecnológico grande", explica Thaisa Storchi Bergmann, chefe do grupo de pesquisa em Astrofísica da Universidade Federal do Rio Grande do Sul. Em conversa com Renata Lo Prete, ela diz que as imagens do Sagittarius A* confirmam conclusões tanto dos vencedores do prêmio Nobel de Física de 2020 quanto da Teoria da Relatividade de Albert Einstein. “Os supermassivos surgiram no centro das galáxias”, ensina Thaisa. “E se formaram junto com elas, no início do Universo”. A astrofísica, responsável por uma importante descoberta sobre buracos negros no começo dos anos 1990, avalia que a foto é um "sucesso de todos” os que estudam o tema. “Culminou numa imagem que confirmou praticamente tudo que a gente vinha concluindo", comemora.

Hier, les astronomes de l'Observatoire européen austral (ESO) et du projet Event Horizon Telescope (EHT) ont révélés de nouvelles informations à propos du trou noir supermassif au centre de la Voie lactée et notamment une toute première image de ce dernier. Plus d'informations avec Stéphane Paltani, astrophysicien à l'Université de Genève. Un sujet préparé par Anne Baecher.

What does it take to capture an image of the black hole at the centre of our galaxy? This video explains how the Event Horizon Telescope (EHT) works, and how astronomers managed to create one massive Earth-sized telescope big enough to “see” at the edge of black holes.

On May 12, 2022, the global Event Horizon Telescope (EHT) collaboration unveiled the landmark first image of the black hole at the heart of our own Milky Way galaxy, called Sagittarius A* (or Sgr A*). On this special episode of Conversations at the Perimeter, Lauren and Colin talk with astrophysicist Avery Broderick about the significance of this discovery. He explains how the EHT collaboration created an “Earth-sized telescope” – a network of eight radio telescopes on five continents, all focussed on a single spot on the night sky: the heart of the Milky Way, 27,000 light-years from Earth. Broderick holds the Delaney Family John Archibald Wheeler Chair at Perimeter, and is an associate faculty member jointly appointed to Perimeter and the University of Waterloo. He also leads the EHT Initiative at Perimeter Institute, which is one of the 13 partner organizations in the EHT. Although his childhood dream of voyaging through the universe on the Starship Enterprise remains out of reach, Broderick says hunting black holes (or "fire donuts," as he playfully calls them) is the next-best thing.

Sagitário A*. Este é o buraco negro localizado ao centro da nossa galáxia, Via Láctea, e pela, primeira vez, traduzido em uma imagem. É a primeira evidência visual da existência deste objeto compacto e supermassivo, possível graças ao trabalho conjunto de uma equipe internacional de pesquisadores, chamada Colaboração Event Horizon Telescope (EHT). Para isso, utilizaram oito radiotelescópios espalhados por diversos pontos do globo terrestre. A partir das imagens captadas, do que simularia um supertelescópio do tamanho da Terra, e da justaposição e da média dos registros, chegou-se à imagem do buraco negro da Via Láctea. De acordo com comunicado do ESO - Observatório Europeu do Sul, embora não seja possível avistar o buraco negro em si, ‘'o gás brilhante que o rodeia revela uma assinatura inconfundível: Para o feito divulgado neste 12 de maio, foram cerca de cinco anos desde a captação das imagens feitas em 2017, mais de 300 profissionais de 80 instituições de diversos países, tecnologia avançada com supercomputadores que analisaram e combinaram dados, além de uma rede mundial de radiotelescópios e colaboração de observatórios no Chile e na Europa. O anúncio sobre o buraco negro no ‘'coração'' da Via Láctea, a cerca de 27 mil anos-luz da Terra, foi realizado na Alemanha, mas mobilizou cientistas e imprensa do mundo todo, assim como em 2019, quando foi anunciada a primeira imagem de um dos objetos mais enigmáticos do Universo, o M87*. A astrofísica Thaisa Storchi Bergmann, membro da ABC – Academia Brasileira de Ciências - destaca o empenho das equipes e da tecnologia utilizada e diz que este anúncio abre portas para avanços nas pesquisas. A cientista reconhecida internacionalmente e que se diz caçadora de buracos negros descreve a emoção de conseguir visualizar o Sagitário A*. Segundo o ESO, os trabalhos da colaboração de pesquisadores continuam em 2022, com expectativa para imagens ainda mais detalhadas e quem sabe até filmes, em um futuro próximo.

In April 2019, scientists released the first image of a black hole in the galaxy M87 using the Event Horizon Telescope (EHT). However, that remarkable achievement was just the beginning of the science story to be told.

Thanks to today’s sponsor, LinkedIn Jobs! Visit linkedin.com/impossible to post your job ad for FREE! The Event Horizon Telescope (EHT) just made a MAJOR Discovery about Black Holes. Chat with Heino Falcke, author of LIGHT IN THE DARKNESS, about what it all means. Light is an oscillating electromagnetic wave. If the waves have a preferred direction of oscillation, they are polarized. In space, moving hot gas, or ‘plasma’, threaded by a magnetic field emits polarized light. The polarized light rays that manage to escape the pull of the black hole travel to a distant camera. The intensity of those light rays and their direction is what we observe with the Event Horizon Telescope. https://licht-im-dunkeln.de/en/home/ GET THE BOOK:https://amzn.to/3lPtpwr MEET HEINO: https://heinofalcke.org Magnetic fields around black holes can launch powerful plasma jets with almost speed of light. They force electrons to gyrate and emit radio waves. This forces the light to oscillate perpendicular to the field lines. On 24 March 2021 the EHT collaboration revealed a breakthrough discovery: the Event Horizon Telescope has imaged polarized light close to the shadow of M87* for the very first time. Using this knowledge, we can map out the magnetic fields that surround the black hole, and connect them to the powerful jet of plasma it ejects. The Event Horizon Telescope (EHT) is an international collaboration that captured the first image of a black hole by creating a virtual Earth-sized telescope.

Spektakulär! Die Magnetfelder des Schwarzen Lochs in der M87-Galaxie konnten erstmals sichtbar gemacht werden! Die erste Aufnahme eines Schwarzen Lochs war eine wissenschaftliche Sensation und ist noch gar nicht so lang her. Nun gibt es das erste Bild, das die Magnetfelder am Ereignishorizont des Schwarzen Lochs in der Galaxie Messier 87 zeigt. Nachdem das Event Horizon Telescope (EHT) vor zwei Jahren das erste Bild eines schwarzen Lochs geliefert hatte, wird nun mit weiteren eindrucksvollen Aufnahmen nachgelegt. Nie ist man den sogenannten Jets näher kommen können als jetzt. Die Fachleute liefern bereits neue spannende Daten zu dem Schwarzen Loch und haben diese bereits auswerten können. 2017 hatte die Auswertung der aufgenommenen Daten noch Luft nach oben, doch dieses Mal hat man sich die Magnetfelder genauer angesehen. Die Visualisierung dieser Magnetfelder ist eine spektakuläre Premiere für die Wissenschaft. Welche Erkenntnisse lassen sich nun aus den neuen Entdeckungen erschließen? Welche Rätsel könnten endlich gelöst werden?

The Event Horizon Telescope (EHT) collaboration, who produced the first ever image of a black hole, has today revealed a new view of the massive object at the centre of the Messier 87 galaxy: how it looks in polarised light. This is the first time astronomers have been able to measure polarisation, a signature of magnetic fields, this close to the edge of a black hole. This video summarises the discovery.

Lorsque l'on manque de nouvelles données à exploiter, on peut toujours se retourner vers des anciennes données remisées dans les tiroirs et voir ce qu'on peut en tirer... C'est ce qu'ont dû se dire les chercheurs de la collaboration Event Horizon Telescope (EHT), qui n'ont rien pu se mettre sous le dent depuis la campagne heureuse de 2017 qui a permis de produire une image de la silhouette du trou noir supermassif M87*. Les campagnes de printemps de l'EHT 2018 et 2019 n'ont en effet pas pu avoir lieu pour de sinistres raisons et celle de 2020 a été annulée à cause d'une saleté de coronavirus. Mais l'EHT existait déjà bien avant 2017, et même si il n'était pas assez développé pour que ses données interférométriques puissent former des images de silhouettes d'horizon de trous noirs, les données peuvent être exploitées a posteriori, avec l'aide des données très riches de 2017. Cela offre aux astrophysiciens l'opportunité d'étudier l'évolution de l'anneau entourant l'ombre de l'horizon du trou noir supermassif, avec une surprise à la clé! Une étude publiée dans The Astrophysical Journal.

Highest resolution Event Horizon Telescope (EHT) observations will probably soon tell us more about the supermassive black hole at the Galactic Centre (Sgr A*) and the cores of active galactic nuclei (AGN). It might also help to clarify the long-standing question whether the central massive objects in AGN are instead close pairs of black holes. Mergers of supermassive black hole pairs would provide the strongest gravitational wave signals. I will present examples of how we identify potential close binary black hole candidates based on the combined analysis of high resolution radio interferometric (VLBI) observations and multi- wavelength data. I will also provide an outlook on the scientific prospects with regard to future EHT-observations.

Dr. Avery Broderick, an astrophysicist who holds the Delaney Family John Archibald Wheeler Chair at Perimeter Institute for Theoretical Physics in Waterloo, shared his collaborative discovery of the first ever glimpse of a black hole, with ideacity. In April 2019, he and colleagues from the Event Horizon Telescope (EHT) collaboration unveiled humanity

On April 10, astronomers announced that they had captured the first images of a black hole through the Event Horizon Telescope (EHT) – a planet scale array of eight ground based radio telescopes forged through international collaboration. University of Illinois Physics Professor Charles Gammie, is a member of the EHT Science Council and co-led a group which provided the theoretical analysis. The team developed sophisticated computer code to make running and analyzing the simulations as efficient as possible. Professor Gammie joins Illinois Innovators to discuss the significance of the discovery, the role the Illinois team played in the project, and what’s next.

For the first time in history, humankind can be witness to one of Einstein's predictions: the existence of black holes. This morning, an international scientific team announced that they were able to see and capture the first-ever picture of a black hole. The black hole is situated at the center of the Messier 87 galaxy, a massive galaxy in the nearby Virgo galaxy cluster.

The April 10 announcement that scientists had created the first-ever image of a black hole — in actuality its shadow, bending and warping a bright ring of light and gas around its mysterious center — was a triumphant moment for members of the Event Horizon Telescope (EHT) project. The supermassive black hole lies at the center of the M87 galaxy, 55 million light years from Earth. Black holes exert a gravitational pull so great that even light cannot escape, though their gravitational bending effects distort light around them. On today's episode, Kwamina argues that black holes don't matter. Selorm doesn't think so.

The multinational team behind the Event Horizon Telescope (EHT), which spans the Earth by linking dishes in 8 different countries, have revealed the first images of the supermassive black hole - that has a mass 6 billion times that of our Sun - sitting at the centre of galaxy Messier 87, fifty-five million light years from Earth. For the first time we can see what a black hole - or rather the space around a black hole - looks like.

Chapter 1

The Event Horizon Telescope (EHT) -- a planet-scale array of eight ground-based radio telescopes forged through international collaboration -- was designed to capture images of a black hole. In coordinated press conferences across the globe, EHT researchers revealed that they succeeded, unveiling the first direct visual evidence of a supermassive black hole and its shadow.

The Event Horizon Telescope (EHT) — a planet-scale array of eight ground-based radio telescopes forged through international collaboration — was designed to capture images of a black hole. In coordinated press conferences across the globe, EHT researchers revealed that they succeeded, unveiling the first direct visual evidence of the supermassive black hole in the centre of Messier 87 and its shadow. The shadow of a black hole seen here is the closest we can come to an image of the black hole itself, a completely dark object from which light cannot escape. The black hole’s boundary — the event horizon from which the EHT takes its name — is around 2.5 times smaller than the shadow it casts and measures just under 40 billion km across. While this may sound large, this ring is only about 40 microarcseconds across — equivalent to measuring the length of a credit card on the surface of the Moon. Although the telescopes making up the EHT are not physically connected, they are able to synchronize their recorded data with atomic clocks — hydrogen masers — which precisely time their observations. These observations were collected at a wavelength of 1.3 mm during a 2017 global campaign. Each telescope of the EHT produced enormous amounts of data – roughly 350 terabytes per day – which was stored on high-performance helium-filled hard drives. These data were flown to highly specialised supercomputers — known as correlators — at the Max Planck Institute for Radio Astronomy and MIT Haystack Observatory to be combined. They were then painstakingly converted into an image using novel computational tools developed by the collaboration. --- Support this podcast: https://anchor.fm/space-news/support

Did you know there is an effort underway to actually see the event horizon of a black hole? Right now, astronomers around the world are processing data taken earlier of the center of our galaxy in attempt to see the boundary between normal space and that of Sag A*, the supermassive black hole at the center of the Milky Way. The results are due out soon and this hangout is your chance to learn about one of the most amazing astronomy endeavours ever attempted from Geoff Bower, Chief Scientist for Hawaii Operations for the Event Horizon Telescope. --- This episode is sponsored by · Anchor: The easiest way to make a podcast. https://anchor.fm/app Support this podcast: https://anchor.fm/deepastronomy/support

Depuis avril 2017, nous sommes tous dans l'attente fébrile de la divulgation de l'image sans précédent de la silhouette de notre trou noir galactique Sgr A par l'Event Horizon Telescope (EHT). Le traitement et l'analyse des données prend beaucoup de temps et une autre campagne d'observation vient d'être effectuée le mois dernier pour enrichir la première moisson. Aujourd'hui, la collaboration de l'EHT publie un résultat!... mais ce n'est pas celui attendu : il s'agit de résultats d'observations de Sgr A datant de... 2013. Ces résultats ont l'intérêt de montrer que les espoirs mis dans les observations de 2017 sont tout à fait justifiés, et ils ont l'avantage de faire patienter les impatients.

Hoy comenzamos el programa con un pareado: “Pulpos, sepias y calamares, una nueva genética de los mares”, porque estos animales desafían un dogma de la biología molecular y celular. Después damos un salto al centro de la Vía Láctea porque hacia allí se enfoca el Telescopio del horizonte de sucesos o Event Horizon Telescope (EHT) para obtener la primera imagen de un agujero negro. Continuamos con un salto hasta lo más pequeño, para descubrir nuevos megavirus o virus gigantes. Y terminamos con una investigación que propone que los instintos pueden proceder de un aprendizaje heredado.
