Update: The study's authors have provided us with a link to a free .pdf version of the full paper ! In a revolutionary development, a team of astronomers has discovered that a faint smudge of a galaxy called NGC1052-DF2 (or DF2, for short) may have no dark matter at all; the group's results show that DF2 has less dark matter than predicted by a factor of at least 400 . That’s a big deal. Astronomers have never seen a galaxy like this before, and it raises intriguing questions about galaxies and dark matter.
