It measures 40 billion km across - three million times the size of the Earth - and has been. 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. Astronomers have taken the first ever image of a black hole, which is located in a distant galaxy. But Einsteins theory of general relativity predicts that within this image there also lies a thin 'photon ring' consisting of multiple mirror images of the main emission. 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 first images of the supermassive black hole M87 display a bright ring encircling the event horizon, which appears as a dark patch in its surrounding emission. The new view captures light bent by the powerful gravity of the black hole, which is four million times more massive than our Sun. The telescope is named after the event horizon, the boundary of the black hole beyond which no light can escape.Īlthough 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. Astronomers have long speculated about a. 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. This is the first image of Sagittarius A (or Sgr A for short), the supermassive black hole at the center of the Milky Way galaxy, 27,000 light-years from. Astronomers using the Event Horizon Telescope (EHT) have taken the first image of the Milky Way's supermassive black hole, named Sagittarius A. It’s the 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.
