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.
