Dwarf Galaxies Orbiting Milky Way Could Hold Vital Clues To Nature Of Dark Matter

Astronomers have discovered a “treasure” of several dwarf galaxies, about a billion times dimmer than the Milky Way, orbiting our galaxy. The discovery, jointly announced by a team of scientists from the University of Cambridge and astronomers associated with the Dark Energy Survey -- a multinational collaboration of research institutes in the U.S. and Europe -- could help scientists unravel the mysterious dark matter that constitutes over 84 percent of all matter in the universe.

The astronomers analyzed publicly available data collected using the Dark Energy Camera located at the Fermi National Accelerator Laboratory in the U.S. and discovered nine new neighbors of the Milky Way.
