Dieses ist das erste Bild von Sagittarius A*, dem Schwarzen Loch im Zentrum unserer Milchstraße. Gewonnen wurde das Bild aus Daten vom Event Horizon Telescope.

  Se parece a aquella impresionante imagen del primer "agujero negro" fotografiado en la historia. Claro, lo que se ve es su disco de acreción.

  1. Sagittarius A*
    
    Sagittarius A* (pronounced "Sagittarius A-Star", abbreviated Sgr A*) is a bright and very compact astronomical radio source at the Galactic Center of the Milky Way. It is located near the border of the constellations Sagittarius and Scorpius, about 5.6° south of the ecliptic, visually close to the Butterfly Cluster (M6) and Shaula. Sagittarius A* is the location of a supermassive black hole, similar to massive objects at the centers of most, if not all, spiral and elliptical galaxies. Observations of several stars orbiting Sagittarius A*, particularly star S2, have been used to determine the mass and upper limits on the radius of the object. Based on mass and increasingly precise radius limits, astronomers have concluded that Sagittarius A* is the Milky Way's central supermassive black hole. The current value of its mass is slightly in excess of 4 million solar masses. On 12 May 2022, astronomers announced the image, for the first time, of Sagittarius A*.Reinhard Genzel and Andrea Ghez were awarded the 2020 Nobel Prize in Physics for their discovery that Sgr A* is a supermassive compact object, for which a black hole is the only currently known plausible...
