First Image Of A Black Hole Expected Today (UPDATED)


Scientific news item:
At last,  April 10 could mark the day scientists have been anticipating for more than a century as the first image of a black hole is expected to finally be revealed. The Event Horizon Telescope (EHT) Collaboration will “present its first results in multiple simultaneous press conferences around the world,” according to a media release. While the EHT team did not specify that an image will be released, scientists around the world are expecting it.
However, an artist's rendering of a black hole has already been provided:

In all seriousness, we hope to share images of the black hole if/when it becomes public.

UPDATE:  Here it is, folks --


A brief explanation of what you're seeing:
True to the nature of the science, the picture does not show the black hole itself. The defining feature of all black holes is that they are so dense, generating a gravity field so powerful, that nothing, not even electromagnetic energy—which, of course, includes visible light—can escape their pull. What the pictures reveal instead is the black holes’ so-called event horizons, the swirl of gas and dust and stars and light itself, circling the black hole drain, before they’re sucked inside never, ever to reemerge.
To use an overused word:  awesome.

I always enjoy your wonderful postings of the beauty of space, so seeing a black hole will be a true thrill. I expect it will be a little bit chilling, too. How cool, and how exciting! I can't wait!

Annnnndd it's cool! Everyone is joking about the Eye of Sauron or the Glazed Donut of Doom, but I think it's amazing. It's great to see a glimpse of something that's always been mysterious. Yay!
