surprising clumpiness

Read an article at about our galaxy's clumpy halo. University of Iowa astronomers using the HaloSat launched from the Space Station observed that the Milky Way is surrounded by a large disc-like halo of hot gases, material that is being both pulled into the galaxy and is being ejected. Recycled material.

X-ray emissions show it is not uniform. 

Also, the researchers are wondering if there are more halos around the galaxy, larger still, dimmer, that may harbour large amounts of baryonic material.
