has event horizon telescope seen a blackhole

“The gas in the vicinity of the black holes moves at the same speed-nearly as fast as light-around both Sgr A* and M87*,” said Chan.

There are differences and similarities between the two black holes. Our own Sagittarius A* black hole is over a thousand times smaller than the black hole at the center of the galaxy M87.

However, the two black holes imaged by the Event Horizon Telescope (EHT) Collaboration are very different. EHT collaboration (acknowledgmen Black hole head-to-head: Sagittarius A* vs. Because of their relative distances from Earth, both black holes appear the same size in the sky. While Sgr A*, 27 000 light-years away, has a mass roughly four million times the Sun’s mass, M87* is more than 1000 times more massive. M87*, which lies 55 million light-years away, is one of the largest black holes known. Also displayed is the Sun’s diameter and the current location of the Voyager 1 space probe, the furthest spacecraft from Earth. The image shows the scale of Sgr A* in comparison with both M87* and other elements of the Solar System such as the orbits of Pluto and Mercury. M87*, at the heart of the galaxy Messier 87, and Sagittarius A* (Sgr A*), at the centre of the Milky Way. Size comparison of the two black holes imaged by the Event Horizon Telescope (EHT) Collaboration. The final image of the Sgr A* black hole is an average of the different images the team extracted using the EHT’s 11 telescopes around the world: “The brightness and pattern of the gas around Sgr A* were changing rapidly as the EHT Collaboration was observing it - a bit like trying to take a clear picture of a puppy quickly chasing its tail,” said EHT scientist Chi-kwan (‘CK’) Chan, from Steward Observatory and Department of Astronomy and the Data Science Institute of the University of Arizona. It uses a global network of radio observatories in unison to effectively create an Earth-sized telescope. The Event Horizon Telescope (EHT) project creates images of black holes. Kassim, Naval Research Laboratory What is the EHT? This giant image was assembled from observations made by the Very Large Array (VLA). The thread-like shapes are not yet understood, but probably trace powerful magnetic field lines. The dense, bright circles are the nurseries of new, hot stars and the bubbles are the graveyards of exploded, massive stars. The bright center is the home of the supermassive black hole, Sagittarius A*. The diagonal line of bright objects in this image of the heart of our Milky Way Galaxy are all. 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 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.
