Hubble Finds Origin of Huge Cloud Crashing into our Galaxy

[CygnusX-1]

In 2008, astronomers discovered that a multi-million-solar-mass cloud named Smith's Cloud would hit the Milky Way's disk in about 27 million years. Now new Hubble observations have identified the mysterious cloud's likely origin.

That cloud certainly has an odd shape, makes me wonder if one of the so far theoretical 'fast moving Galactic scale black hole' could have torn a chunk from the gas passing thru, the cloud has a sort of bunched up look, similar to cotton candy caught on a stick, the BH being said stick, yet it has obviously moved on fast enough that the could was stripped away from it's tenuous hold by the extremely hot gas and plasma surrounding the galaxy. Nice Find!
