Black holes

From Sagittarius A* at the centre of the Milky Way to M87*, the first ever imaged, from X-ray binaries to supermassive giants: known black holes with their masses and event horizons.

• Sagittarius A* The supermassive black hole at the centre of the Milky Way
• M87* The first black hole ever imaged (EHT 2019), centre of Virgo A

• Gaia BH1 The nearest known black hole — quiet, no disc (lensing only)
• V404 Cygni X-ray nova famous for its 2015 outburst
• A0620-00 A quiet X-ray nova in Monoceros (V616 Mon)
• LMC X-1 The first extragalactic black hole, in the Large Magellanic Cloud
• LMC X-3 A slowly spinning black hole paired with a B star in the LMC
• M33 X-7 An eclipsing massive X-ray binary in the Triangulum Galaxy
• M31* The sleeping giant at the centre of Andromeda (140 million M☉)
• Centaurus A* The nearest active galactic nucleus; giant radio jets
• Sombrero kara deliği Centre of the Sombrero Galaxy · 1 billion M☉
• M106 kara deliği The black-hole mass measured most precisely, using water masers
