Our cosmic neighborhood may be far more crowded than previous estimates have suggested. New research hints the Milky Way could have many more small dwarf galaxy “satellites” around it than expected. The team, comprised of cosmologists from Durham University, combined supercomputer simulations with mathematical modeling to predict the existence of missing Milky Way “orphan” galaxies. The researchers’ novel technique suggests …

100 undiscovered galaxies may be orbiting the Milky Way, supercomputer simulations hint
The Milky Way may be surrounded by dozens of yet-to-be-detected satellite galaxies, scientists claim. Using the highest-resolution simulation of our galaxy’s dark matter — an invisible entity that shapes the large-scale structure of the universe — and new mathematical models, cosmologists predict that more than 100 additional satellite galaxies beyond the ones already cataloged may be swirling around our own. …

The Lambda Cold Dark Matter (LCDM) theory suggests that most galaxies are low-mass dwarf galaxies, many of which orbit larger galaxies like the Milky Way. More broadly, the LCDM represents our best understanding of how the universe works. But there’s a problem. According to the theory, the Milky Way should have significantly more satellite galaxies than scientists have observed with …
