Something Huge and Invisible Is Making Nearby Stars Vanish, Scientists Propose

If I’m reading this right, and if it’s written right, it appears that the Hyades star cluster, some 153 light years away, has a few “tails” of stars and gas. But one of the tails seems to have had a number of stars yoinked out of it by something that is not visible. It seems that some scientists think it might be a mass of dark matter massing about 10 million times the sun.

It seems odd to me that there might be a ten million solar mass *anything* only a few hundred light years away…
