New dark matter map reveals cosmic mystery
The most detailed map of dark matter in the Universe is puzzling physicists. …
But the new dark matter map is not showing quite what astronomers expected. They have an accurate idea of the distribution of matter 350, 000 years after the Big Bang, from a European Space Agency orbiting observatory called Planck. It measured the radiation still present from that moment, called the cosmic microwave background, or more poetically, the “afterglow of creation”.
