When Black Holes Collide

A video illustrates two black holes merging, showcasing gravitational lensing effects on nearby stars. The event horizons and a combined Einstein ring are visible, with stars appearing inside and outside the ring. The merger emits strong gravitational waves, offering new cosmic insights. #BlackHoleWeek

Celebrating #BlackHoleWeek, some of our scientists are working with the Science Ceilidh #SciComm team to create a binary black hole themed dance. Science Ceilidh work to connect researchers with their local communities through the arts. The final dance will be shared with participants at the upcoming #GR24Amaldi16 conference.

It's #BlackHoleWeek!

You might not expect it, but NSF–DOE Rubin Observatory's observations in visible light will help us learn about these dark and mysterious cosmic entities. But how?

Rubin won't observe black holes directly. Instead, it'll observe super-bright blasts of light called Active Galactic Nuclei, which are powered by hungry supermassive black holes.

AGN are some of the brightest objects in the Universe, which means we can see them extremely far away.

Apparently it's #BlackHoleWeek!

Here's a conceptual black hole and our very own Sagittarius A*.🥳

Did you know if you get to close to a black hole you'd be spaghettified?🤭
