Hubble identifies a near-invisible galaxy that may be 99% dark matter Preliminary analysis suggests CDG-2 has the luminosity of roughly 6 million sun-like stars, with the globular clusters accounting for 16% of its visible content. Remarkably, 99% of its mass, which includes both visible matter and dark matter, appears to be dark matter. Much of its normal matter to enable star formation—primarily hydrogen gas—was likely stripped away by gravitational interactions with other galaxies inside the Perseus cluster.
