Astronomers have discovered a black hole the likes of which have never been seen before

Astronomers have discovered a dormant black hole unlike any discovered before. They say there is no explanation for the unexpected data showing a stellar-mass black hole in the Large Magellanic Cloud, the Milky Way's neighboring galaxy.
The star that caused the black hole appears to have disappeared without a big explosion, researchers say. Researchers have described the black hole as a "needle in the haystack." Astronomers believe that dormant black holes are relatively common throughout the universe, but we know very little about them and confirmed examples are rare.
They are difficult to spot mainly because being dormant means they don't interact much with the environment. Researchers have spent years looking for them, but have had difficulty identifying even this specimen.
There are also a whole host of explanations for many of the phenomena that point to such black holes, making their confirmation difficult.
To find this black hole, researchers analyzed nearly 1,000 massive stars in the Large Magellanic Cloud. They looked for examples of stars that might have accompanying black holes.
Finally, they discovered VFTS 243. The researchers checked whether it was indeed a dormant black hole, given the skepticism surrounding such discoveries, and say they're confident in what they've found - but want to continue their research.
