A Picture of the Milky Way’s Supermassive Black Hole


[embedded content]

Space aside for a moment, whenever the Milky Way’s supermassive black hole, Sagittarius A*, comes up the only thing I think is “wow that sounds like a delicious ice cream”. Call me food motivated… or maybe I just need to find an ice cream that has candy and cake in it ¯_(ツ)_/¯. Anyway, Veritasium published the video above about Sagittarius A*

So now that we’re thinking about black holes (and ice cream, you’re welcome) Center for Astrophysics compares M87* and Sgr A* in this ~90s video

We’ve watched the videos, now it’s time to do the reading from Even Horizon Telescope:

Because the black hole is about 27,000 light-years away from Earth, it appears to us to have about the same size in the sky as a donut on the Moon. To image it, the team created the powerful EHT, which linked together eight existing radio observatories across the planet to form a single “Earth-sized” virtual telescope [1]. The EHT observed Sgr A* on multiple nights, collecting data for many hours in a row, similar to using a long exposure time on a camera.

Like a donut on the Moon. 🍩🌝
