Perhaps not

A little while ago I pointed to an amazing paper which argued that there's a black hole in a naked-eye-visible star system, about 1000ly from us. There may not be:
- Is HR 6819 a triple system containing a black hole? – An alternative explanation
- A stripped-companion origin for Be stars: clues from the putative black holes HR 6819 and LB-1
- The nearest discovered black hole is likely not in a triple configuration
So, that's sad, but it's also a good example of science doing its job: someone claimed something which was plausibly correct & some other people looked at the data behind the claim and found that, probably, it was not correct after all.
