Thanks to new techniques, astronomers are mapping the Universe with more precision, finding galaxies with more and less dark matter. Now astronomers think they've found one that's almost all dark matter with few stars. Dubbed "Nube", the galaxy contains about the same mass as the Large Magellanic Cloud, measuring 22,000 light-years across, with almost no stars inside it. This is the most massive and extended "Almost Dark Galaxy" astronomers have ever found.
