巨大ブラックホールの輪郭撮影 天の川銀河で初成功 （提供写真）

Three NASA telescopes, help astronomers learn more about the Milky Way's supermassive black hole, captured in the latest remarkable image from the Event Horizon Telescope (EHT). The Chandra X-ray Observatory, Nuclear Spectroscopic Telescope Array (NuSTAR), and the Neil Gehrels Swift Observatory (Swift) all observe X-rays from their positions in Earth orbit. X-rays pass through much of the gas and dust that blocks the optical view of the center of the Galaxy some 27,000 light years from Earth. The new EHT image of the Milky Way's central black hole — known as Sagittarius A (abbreviated as Sgr A) shows the area close to the "event horizon," the boundary of a black hole from which nothing can escape. The image is based on data obtained in April 2017. As reported in our latest release, simultaneous observations with Chandra, Swift and NuSTAR reveal what is happening farther out, where the gravitational forces from Sgr A impact the surroundings. The main panel of this graphic contains X-ray data from Chandra (blue) depicting hot gas that was blown away from massive stars near the black hole. Two images of infrared light at different wavelengths from NASA's Hubble Space Telescope show stars (orange) and cool gas (purple). These images are seven light-years across at the distance of Sgr A. A pull-out shows the new EHT image, which is only about 1.8 x 10-5 light-years across (0.000018 light-years, or about 10 light-minutes). Along with the X-ray data from Chandra, NuSTAR, and Swift, scientists in the EHT's 2017 campaign also obtained radio data from the East Asian very long-baseline Interferometer (VLBI) network and the Global 3 millimeter VLBI array; and infrared data from the European Southern Observatory's Very Large Telescope in Chile.

This is the first image of Sagittarius A* (or Sgr A* for short), the supermassive black hole at the center of our galaxy. It was captured by the Event Horizon Telescope (EHT), an array which linked together radio observatories across the planet to form a single "Earth-sized" virtual telescope. The new view captures light bent by the powerful gravity of the black hole, which is four million times more massive than our Sun.

This handout image released by the European Southern Observatory (ESO) on May 12, 2022, shows the first image of Sagittarius A*, the supermassive black hole at the centre of our own Milky Way galaxy. An international team of astronomers on May 12, 2022, unveiled the first image of a supermassive black hole -- a cosmic body known as Sagittarius A*. The image, produced by a global team of scientists known as the Event Horizon Telescope (EHT) Collaboration, is the first, direct visual confirmation of the presence of this invisible object, and comes three years after the very first image of a black hole from a distant galaxy. Black holes are regions of space where the pull of gravity is so intense that nothing can escape, including light. - RESTRICTED TO EDITORIAL USE - MANDATORY CREDIT "AFP PHOTO / European Southern Observatory" - NO MARKETING NO ADVERTISING CAMPAIGNS - DISTRIBUTED AS A SERVICE TO CLIENTS (Photo by Handout / EUROPEAN SOUTHERN OBSERVATORY / AFP) / RESTRICTED TO EDITORIAL USE - MANDATORY CREDIT "AFP PHOTO / European Southern Observatory" - NO MARKETING NO ADVERTISING CAMPAIGNS - DISTRIBUTED AS A SERVICE TO CLIENTS
