The first photo of a black hole

The first photo of a black hole

Ok, this is pretty cool. We have the first photo of a supermassive black hole, from imagery taken two years ago of the elliptical galaxy M87 (in the constellation Virgo) by the Event Horizon Telescope project. The EHT team is a group of 200 scientist that has been working on this project for two decades. The image was created using data captured from radio telescopes from Hawaii to the South Pole and beyond using very long baseline interferometry.

The image, of a lopsided ring of light surrounding a dark circle deep in the heart of the galaxy known as Messier 87, some 55 million light-years away from here, resembled the Eye of Sauron, a reminder yet again of the power and malevolence of nature. It is a smoke ring framing a one-way portal to eternity.

Now is a good time to (re)read Jonathan Lethem’s early novel, the absurdist physics love story As She Climbed Across the Table.

Update: Vox’s Joss Fong has a good 6-minute video that explains how the photo was taken:

And this video by Veritasium is even more meaty (and this one too):
