The Event Horizon Telescope focused on two supermassive black holes: the four-times the sun size, Sagittarius A*, which lies at the heart of this galaxy, and a super black hole about 1,500 times heavier at the core of the nearby galaxy M87. Getting this far took several years of study and coordination, besides the necessary cooperation between different observatories around the world, going from Hawaii to the South Pole. “Even if the first images are still crappy and washed out, we can already test for the first time some basic predictions of Einstein’s theory of gravity in the extreme environment of a black hole,” said Falcke. According to Falcke, this images will indeed turn black holes from some mythical conception to something concrete that can be studied.

Astronomers explain the mystery of magnetically powered jets produced by supermassive black holes. Radio astronomer Heino Falcke – of Radboud University in Nijmegen, The Netherlands – said that black holes are the ultimate endpoint of space and time. Scientists are going to test Einstein’s theory of gravityĮinstein proposed for the first time the existence of extremely massive black holes in 1915, but even he doubted his prediction afterward.
The event horizon is the limit beyond which nothing at all can escape. Now an international team of astronomers, including researchers at MIT’s Haystack Observatory, has captured the light around our own supermassive black hole, revealing for the first time, an image of Sagittarius A (Sgr A, pronounced ‘sadge-ay-star’), the black hole at the heart of the Milky Way galaxy. All the scientists involved is especially interested in having the picture of the event horizon, which is a difficult region that surrounds the black hole. However, they are not sure yet about their success, because there is a lot of data to be processed in the forthcoming months, and though, they are confident they have finally captured a black hole for the first time, the actual photos are not going to be available until the end of 2017. “I’m very happy and very relieved, and I’m looking forward to getting a good night’s sleep,” Fish says. As the last of the data arrived at the observatories, all the astronomers and engineers were celebrating, and Fish was listening to the chords of bohemian rhapsody.

From April 5 to April 14, astronomers around the world will do everything they can to capture the first photographs of Sagittarius A*, which is the supermassive black hole in our Galaxy. They supermassive black holes they observed were Sagittarius A*, which is the black hole located in the middle of our galaxy, and the one in the core of galaxy M87. After five nights of observations, today astronomers revealed they had finally captured the first-ever image of the famous gravitational sinkhole known as a black hole. The Even Horizon Telescope resulted from an alliance between scientists from different observatories around the world. The image is not going to be published yet. It comes from the same team of over 300 international scientists who produced the first ever image of a black hole in another galaxy in 2019.The Event Horizon Telescope apparently had succeeded to complete its ten-day long task of taking the very first picture of a black hole even before it was planned.
The first ever image of the supermassive black hole at the center of our galaxy has been published by the Event Horizon Telescope (EHT). In addition to other facilities, the EHT network of radio observatories that made this image possible includes the Atacama Large Millimeter/submillimeter Array (ALMA) and the Atacama Pathfinder EXperiment (APEX) in the Atacama Desert in Chile, co-owned and co-operated by ESO is a partner on behalf of its member states in Europe. The image of the Sgr A* black hole is an average of the different images the EHT Collaboration has extracted from its 2017 observations. The new view captures light bent by the powerful gravity of the black hole, which is four million times more massive than our Sun. Although we cannot see the event horizon itself, because it cannot emit light, glowing gas orbiting around the black hole reveals a telltale signature: a dark central region (called a shadow) surrounded by a bright ring-like structure. The telescope is named after the event horizon, the boundary of the black hole beyond which no light can escape. It was captured by the Event Horizon Telescope (EHT), an array which linked together eight existing radio observatories across the planet to form a single “Earth-sized” virtual telescope. first direct visual evidence of the presence of this black hole. This is the first image of Sgr A*, the supermassive black hole at the centre of our galaxy.
