And Here It Is…


From The Event Horizon Telescope (EHT)

This is the first ever photograph of a black hole.  Not what you expected?  Well, to a VERY small degree, that’s because I lied to you in my last post when I said that it would be the black hole at the center of our Milky Way galaxy, Sag A*.  This is actually the center of M87, a supermassive galaxy in the constellation Virgo.  Although it is about 53 million light-years away, it is apparently large enough that it made a better target than Sag A*.  But the EHT team reports that an image of Sag A* is coming soon.

If you want to learn more about the structure of a black hole and the “event horizon”, here’s a video that I found helpful: https://www.youtube.com/watch?v=zUyH3XhpLTo


About Greg Marshall

I am a retired electronics engineer and after a few months of enjoying my leisure I began to miss doing product development. My astronomy hobby always needed new solutions to unique problems, so I decided that whenever I came up with a good solution I would try to make it available to others.
