Galaxies Grow Up in Dark Matter Nurseries - Universe Today
Want to know where new galaxies are going to be born? Just look for clumps of dark matter. Although dark matter is completely invisible to any kind of detector we have today, this mysterious substance can warp radiation by its gravity. Astronomers have used Hubble and the Subaru Telescope to map out the distribution of dark matter in an area of sky 5 times larger than the full Moon. Wherever dark matter is at its thickest, galaxies are likely to form.
