![]() “We think we’re looking at a hot bubble of gas zipping around Sagittarius A* on an orbit similar in size to that of the planet Mercury, but making a full loop in just around 70 minutes,” Wielgus said in a statement. One notable fact about the bubble is the tremendous speed at which it is moving, according to lead researcher Maciek Wielgus of the Max Planck Institute for Radio Astronomy. It was captured by the Event Horizon Telescope (EHT) collaboration. This is the first image of Sagittarius A* (or Sgr A* for short), the supermassive black hole at the center of our galaxy. This bubble of gas wasn’t seen in the image of Sagittarius A* (which was captured by a collaboration called the Event Horizon Telescope) but instead was inferred from observations using the Atacama Large Millimeter/submillimeter Array (ALMA). ![]() Sagittarius A* and animation of the hot spot around itĪs shown in this video animation, the bubble of hot gas is moving around the black hole in a similar manner to the way the Earth orbits the sun. ![]()
