: It is estimated to be 6.5 billion times the mass of the Sun .

: The famous 2019 image shows a bright, asymmetrical ring of light surrounding a dark central "shadow". This ring is caused by light bending in the intense gravity of the black hole, with the brighter side resulting from the Doppler effect as material rotates toward Earth. : It is estimated to be 6

: Follow-up observations, including polarized light images released in 2021, have mapped the strong magnetic fields at the black hole’s edge. These fields are critical for understanding how the black hole launches its signature jets. : It is estimated to be 6
