It's #BlackHoleWeek! What happens when two black holes merge? Gravitational waves may help solve this mystery and NSF @NANOGrav is on a mission to find the answer. Watch this video to learn more. www.youtube.com/watch?v=c2EKbvnee3o

1/ It’s #BlackHoleWeek! ⚫🌌 This week we’ll show you what ESO telescopes 🔭 have been up to since last year in the study of black holes. Starting with finding the link between the explosive deaths of massive stars and black hole formation! 💥🌌 👇 www.youtube.com/watch?v=TPImj75Zl10

When two black holes merge they emit a huge amount of energy as gravitational waves. The peak luminosity in gravitational waves is greater than the luminosity in visible light of all the stars we can see in the Universe #BlackHoleWeek 🎬: SXS Collaboration pic.twitter.com/BhXoXGauGE

The polarized light rays that manage to escape the pull of the black hole travel to a distant camera. The intensity of the light rays and their direction are what we observe with the Event Horizon Telescope. What is Polarization?🤔 📹:@ehtelescope Collaboration and Fiks Film pic.twitter.com/9ysAuBmGeQ
