    Recently a Joint Newsletter from European Southern Observatory (ESO) And thisEvent Horizon Telescope (EHT) has announced that an online conference will be held on May 12, 2022 in France at 3:00 pm, which will report new results and specifically The largest black hole Of Milky Way. This is more than 4 million Masses Like the sun and everything else Black holes Too big, we don’t know how it came to be. We are not sureStar The compact was ejected to our hub Galaxy With this mass, it may seem like the most feasible, but actually a black hole. On the other hand, we know many stars of this type, but they are very light in weight and are considered black holes in the Milky Way. Their origin is less mysterious because they are called star-mass black holes, usually 5 and 15 times heavier. The sun. Let’s make some reminders about these Star black holes I take what Futura explained about them in a previous article. When a Star More than 8 solar masses fall in gravity after discharging its nuclear...
    EHT Collaboration, CC BY-SA This image shows Sagittarius A*, the black hole at the center of the Milky Way galaxy. On May 12, 2022, astronomers on the Event Horizon Telescope team released an image of a black hole called Sagittarius A* that lies at the center of the Milky Way galaxy. Chris Impey, an astronomer at the University of Arizona, explains how the team got this image and why it is such a big deal. 1. What Is Sagittarius A*? Sagittarius A* sits at the the center of our Milky Way galaxy, in the direction of the Sagittarius constellation. For decades, astronomers have been measuring blasts of radio waves from an extremely compact source there. In the 1980s, two teams of astronomers started tracking the motions of stars near this mysterious source of radio waves. They saw stars whirling around a dark object at speeds up to a third of the speed of light. Their motions suggested that at the center of the Milky Way was a black hole 4 million times the mass of the Sun. Reinhard...
    Astronomers at the United States National Science Foundation and the Event Horizon Telescope Collaboration announced on Thursday that they have successfully photographed the supermassive black hole lurking at the center of our Milky Way galaxy. Thursday's mindblowing breakthrough will be published in a forthcoming special issue of The Astrophysical Journal Letters. The colossal object, known as Sagittarius A*, is located 27,000 light-years away from Earth in the direction of the constellation Sagittarius. It was first discovered in 1974 by Bruce Balick of the Astronomy Department at the University of Washington in Seattle and Cornell University's Robert Brown. Sagittarius A*'s properties were later confirmed in the 1990s by a world-renowned group of researchers – Andrea Ghez, an astrophysicist and professor in the Department of Physics and Astronomy at the University of California, Los Angeles, Reinhard Genzel of the Max Planck Institute for Extraterrestrial Physics in Garching, Germany, and the University of California Berkeley, and Oxford University's Sir Roger Penrose. Using radio telescopes to peer through the haze of interstellar dust that absorbs visible light, Ghez, Genzel, and Penrose observed stars...
    It’s just over three years to the day that I wrote about the first ever image of a black hole being obtained in a galaxy known as M87. Today, the long anticipated image of the black hole residing in the center of our very own Milky Way Galaxy was released. The worldwide collaboration of telescopes called the Event Horizon Telescope (EHT) took data starting in 2017 of our Milky Way Galaxy’s own supermassive black hole, Sagittarius A* (Sgr A*) — pronounced “sadge-ay-star.” It is a black hole beast at the center of our galaxy that is 4.4 million times the mass of our Sun. For decades, astronomers have studied the galactic center of the Milky Way, including Sgr A*, and getting an image of our galaxy’s black hole was a high priority for EHT.

    Scientists unveiled the first picture of the black hole that forms the heart of the Milky Way galaxy Thursday during a press conference hosted by the National Science Foundation with the Event Horizon Telescope Collaboration in Washington, D.C. The image is the product of a team effort by the Event Horizon Telescope, or EHT Collaboration, and it was brought to life using a worldwide network of radio telescopes, according to a release from the NSF. The price tag for the effort was about $60 million, with approximately $28 million coming from the NSF, according to a report. TOM BRADY TO JOIN FOX SPORTS AS LEAD NFL ANALYST AFTER RETIREMENT The picture of the black hole, named Sagittarius A*, is proof that such a body sits at the center of the galaxy, and it can offer scientists a myriad of clues about how celestial giants operate. According to the release, the black hole itself cannot be seen, but the glowing gas represents its "telltale signature," which is a dark central area adorned with a...
    For the first time, astronomers have captured an image of the supermassive black hole at the center of our galaxy. It’s the first direct observation confirming the presence of the black hole, known as Sagittarius A*, as the beating heart of the Milky Way. Black holes don’t emit light, but the image shows the shadow of the black hole surrounded by a bright ring of light, which is bent by the gravity of the black hole. Astronomers say the black hole is 4 million times more massive than our sun. It has taken years for astronomers to capture and confirm this image and discovery. Previously, scientists observed stars orbiting some invisible, massive object at the galactic center. The discovery was made possible by more than 300 researchers from 80 institutions working with a network of eight different radio telescopes around the globe that comprise the Event Horizon Telescope. The telescope is named after the “event horizon,” the point at which no light can escape from a black hole. The-CNN-Wire ™ & © 2022 Cable News Network, Inc., a WarnerMedia Company....
    Three years ago, scientists revealed that they had “seen what we thought was unseeable”: a picture of a black hole. In reality, we can’t outright see a black hole—an object so dense that light cannot escape it. But what the team at the Event Horizon Telescope (EHT) managed to do was capture its bright silhouette, composed of extremely hot, super-charged gas and plasma that swirls around the black hole’s “event horizon,” or the point of no return. On Thursday, the EHT told the world it had gone a step further and taken the first ever photo of Sagittarius A* (Sgr A*), the supermassive black hole that sits at the center of the Milky Way. “This is the first image of the supermassive black hole at the heart of our galaxy,” Sera Markoff, an astronomer and EHT team member based at the University of Amsterdam, told reporters Thursday. “Today, we have direct evidence that this object is a black hole.” The 2019 announcement was of the supermassive black hole at the center of Messier 87 (or M87), a galaxy 53 million...

    Astronomers from the Southern European Laboratory have announced a conference where they will present a mysterious discovery that could be presented as “revolutionary” in relation to the Milky Way. The team of eminent astronomers has provoked the community of all astronauts and amateurs by mocking the announcement of a “revolutionary” discovery in our Milky Way. These results will be announced on May 12th, and we can say that there is a lot to be interested in. In fact, if this mysterious and surprising rowdy announcement had come from a Lambda laboratory it would have been almost a story. But it is actually the opposite; The message comes directly from the dignitaries European Southern Observatory (ESO)A company obviously does not usually go into a state of turmoil. And, above all, it’s about resultsEvent Horizon Telescope (EHT). In this context, astronomers tremble at the mere mention of an important conclusion. And for good reason: the same machine made production possible The world’s first live image of the black hole. An important step for experts, but it also had implications for...
    How to make the black hole visible? Astronomers have been photographing a star near the Milky Way’s central black hole for 20 years and watching the star dance around Sagittarius A *. The S2 star can be seen in the center of the photo. The star is located 26,000 light-years from Earth. You can clearly see the star accelerating at certain times and dancing around the black hole in time. At that time, the speed of this star was 25 million kilometers per hour. This is 7,000 kilometers per second or 3% of the speed of light. Suppose you have to travel from Earth to the Sun at this speed, a one-way journey is only six hours. The deadline below is ESO’s Largest Telescope (VLT) and Released in 2018. The black hole is not visible in the photo. However, if you follow the S2 star, you will know where this black hole is lurking. This is the first time that scientists have tested Albert Einstein’s theory of general relativity near a black hole. “Einstein’s general theory of relativity does...
    A rare 'missing link' black hole has been found in the Milky Way's closest large galactic neighbour, a new study reveals.  Astronomers say the black hole has an 'intermediate-mass', and is the rare third type of black hole that has only recently come to light.  Described as 'unlike any other', the black hole was found in a star cluster called B023-G078 in the Andromeda galaxy.  Otherwise known as Messier 31 or M31, Andromeda is the closest large spiral galaxy to our galaxy, the Milky Way.  This newly-found black hole has a mass 100,000 times greater than our Sun, making it smaller than black holes found at the centre of galaxies (supermassive black holes), but bigger than black holes born when stars explode (stellar black holes).   One theory is that intermediate-mass black holes could be the seeds from which supermassive black holes grow.   The black hole was found hidden within B023-G078, an enormous star cluster in Andromeda with a solar mass of 6.2 million. The left panel shows a wide-field image of M31 with the red box and inset showing the location and...
    Astronomers have revealed the 'deepest and sharpest images to date' of the region around our Milky Way galaxy's supermassive black hole. The stunning new images, captured at various times earlier this year and released today by the European Southern Observatory (ESO), show several stars moving around their orbit of the black hole, Sagittarius A*. ESO researchers used the Very Large Telescope (VLT), located in the Atacama Desert of northern Chile, to take the shots, which zoom in 20 times more than what was possible before.   They have also revealed a never-before-seen star close to the black hole, called S300 and provide the most precise estimate of the mass of the Milky Way's central black hole to date – 4.3 million times that of the Sun.   'The best way to answer these questions is to follow stars on orbits close to the supermassive black hole. And here we demonstrate that we can do that to a higher precision than ever before.'  Black holes are regions of spacetime where gravity pulls so much that even light can not get out. They act as intense...
    Our Milky Way's supermassive black hole has a 'leak', NASA scientists have revealed.  The black hole, called Sagittarius A*, periodically emits a 'blowtorch-like jet' out into space through this leak, perhaps once every several thousand years, NASA says.  It's thought the black hole 'burps out' this jet every time it swallows something hefty like a gas cloud, and the jet then hits a huge hydrogen cloud.    Sagittarius A* is at the galactic centre of our Milky Way and has a mass that's 4.1 million times that of our Sun.   Scroll down for video  The black hole, called Sagittarius A*, periodically emits a 'blowtorch-like jet' out into space through this leak, perhaps once every several thousand years, NASA says (artist's impression) SUPERMASSIVE BLACK HOLES ARE AT THE HEART OF GALAXIES Supermassive black holes are objects found at the heart of most galaxies.  They have a mass millions to billions of times the mass of the Sun and allow nothing to escape, not even light.  In the Milky Way the supermassive black hole is known as Sagittarius A*.  There is also a class of ultramassive...
    This is unheard of and calls into question the development patterns of galaxies and supermassive black holes. Leo I, a dwarf galaxy orbiting the Milky Way, has a black hole similar to our galaxy in its center. In the late 1960s, a handful of researchers, including Martin Reese, but especially his colleague and compatriotAstronomer The British Donald Linden-Bell argued that most large galaxies should rest at their centers. Larger black holes. This is essentially a study that has been accepted for at least 20 years, although the definitive evidence for the existence of objects with a phenomenon horizon is still missing, in line with the predictions of the theory of general relativity. It was also observed that there is often a significant and consistent relationship of proportions between Masses Massive black holes and galaxies provide them, which often involves a common developmental mechanism. When galaxies are desired Milky Way Where M87 Dwarf galaxies were clusters, so they must have black holes, which are certainly very large, but smaller than what we can see in their hearts today. Dwarf galaxies known...
    Astronomers may have discovered the first planet ever discovered outside the Milky Way, 28 million light-years from Earth. Experts using NASA's Chandra X-Ray Observatory and the European Space Agency's XMM-Newton telescope may have discovered the planet in the spiral galaxy Messier 51 (M51), also known as the Whirlpool galaxy. All of the exoplanets that have been discovered so far (more than 4,000 of them) have been spotted in the Milky Way, with most less than 3,000 light-years from Earth. If this planet is confirmed, it would 'thousands of times farther away than those in the Milky Way,' a NASA statement said. Astronomers nay have found the first planet outside the Milky Way The potential planet may reside in the spiral galaxy Messier 51, 28 million light-years away from Earth 'We are trying to open up a whole new arena for finding other worlds by searching for planet candidates at X-ray wavelengths, a strategy that makes it possible to discover them in other galaxies,' the study's lead author, Rosanne Di Stefano of Harvard University's Center for Astrophysics, said in a statement....
    Scientists at the Harvard and Smithsonian Center for Astronomical Physics believe that, as a rule, supermassive black holes are located at the center of galaxies. Scientific warning. But after research, they suggested that some of these black holes prefer to travel in the galaxy. Researchers call such black holes “wanderers” and it is almost impossible to see them directly, but a new special simulation has allowed a team of scientists to determine such “wanderers” and their location in the universe. This will help scientists understand how these amazing black holes, which are billions of times the mass of the Sun, form and grow. Astronomers believe that supermassive black holes exist in almost all galaxies, but do not fully understand how they form. See also: The black hole in the center of the Milky Way began to absorb more material Scientists know that black holes form when the nuclei of the largest stars collapse, but this mechanism does not work for black holes, whose mass is 55 times that of our Sun.

    Sagittarius A*, the supermassive black hole at the center of the Milky Way galaxy, is surrounded by orbiting stars thanks to its mammoth gravitational pull. For decades, astronomers have been observing one specific star in this region, and new research proves once again, that Albert Einstein knew a thing or two about gravity.  In a study published Thursday in the journal Astronomy & Astrophysics, researchers revealed for the first time that a star "dancing" around Sagittarius A* moves just as Einstein predicted with his general theory of relativity. The team of scientists studied the star for 27 years using European Southern Observatory's Very Large Telescope in Chile's Atacama Desert, hoping to unlock the mysteries of the gargantuan black hole at the heart of our galaxy. Isaac Newton's theory of gravity predicted a star would orbit the black hole in an elliptical manner, but researchers found S2's orbit is actually shaped like a rosette around the black hole, which is located 26,000 light years from the sun.  "Einstein's General Relativity predicts that bound orbits of one object around another are not...
    A new map of the Milky Way created by the National Astronomical Observatory of Japan shows Earth is spiraling faster and is 2,000 light years closer to the supermassive black hole at the center of our galaxy than was previously thought.  In 1985, the International Astronomical Union announced that Earth was 27,700 light years away from the black hole, named Sagittarius A*. But a 15-year analysis through Japanese radio astronomy project VERA found that the Earth is actually only 25,800 light years away. They also found that Earth is moving 7 km/s faster than they previously believed. Sagittarius A* and black holes of the like are dubbed "supermassive" for a reason — they are billions of times more massive than the sun.  But the NAOJ said there is no need to worry, as the latest data does not indicate the planet is "plunging towards the black hole." It just means there is now a "better model of the Milky Way galaxy."  Position and velocity map of the Milky Way Galaxy. Arrows show position and velocity data for the 224...
