Paint it, Black

Ron gets a mysteriously dark no-prize for bringing us news of possibly the first "dark matter" galaxy ever observed:

Clouds of hydrogen, detected by their unique radio waves, usually mean astronomers have found a galaxy of stars, which can be confirmed with an optical telescope.

Kilborn and team found a cloud of hydrogen using a radio telescope at the UK's University of Manchester. The cloud did not match any known galaxy, so the researchers thought it might be another new galaxy.
To their surprise, they found no stars in the isolated cloud.

The finding is not definitive, but it has potential. More data is, as always, needed to be sure.
