Did you know that supermassive black holes are found in a unique class of galaxies called compact symmetric objects? They are characterized for emitting super-fast power jets. To learn more, visit: bit.ly/4dt0PeH 📹: B. Saxton/@TheNRAO/AUI/NSF #BlackHoleWeek pic.twitter.com/cZvvw7f7oE

Sagittarius A*, the black hole at the center of the galaxy, has a mass 4.3 million times greater than the sun. It comprises 99.9% of the mass at the center of the Milky Way. 📌 bit.ly/3JR7Poc 📷 @geminiobs @NOIRLabAstro/ NSF/AURA/J. da Silva #BlackHoleWeek pic.twitter.com/KriQYlAUNs

We have observed a diverse family of black holes using #GravitationalWaves We now now they come in a range of sizes, but what are the biggest and smallest black holes we have discovered? #BlackHoleWeek 1/🧵 📊: @NUCIERA pic.twitter.com/RlMdZ3w8gF

Gravitational-waves provide a unique way to study black holes This Orrery (by @actualdrdoctor) illustrates the diverse black hole binaries and neutron star black–hole binaries from our O3b run. More massive binaries are shown as orbiting more slowly #BlackHoleWeek pic.twitter.com/bO3PbNDY32
