Scientists using data from the Atacama Cosmology Telescope in Chile have made a detailed map of dark matter’s distribution across a quarter of the sky.First Full-Color Images From Webb Space TelescopeThe map shows regions the distribution of mass extending essentially as far we can see back in time; it uses the cosmic microwave background as a backdrop for the dark matter portrait. The team’s research will be presented at the Future Science with CMB x LSS conference in Kyoto, Japan.“We have mapped the invisible dark…

Researchers used data from the Dark Energy Survey and the South Pole Telescope to re-calculate the total amount and distribution of matter in the universe. They found that there’s about six times as much dark matter in the universe as there is regular matter, a finding consistent with previous measurements.But the team also found that the matter was less clumped together than previously thought, a finding detailed in a set of three papers, all published this week in Physical Review D.The Dark Energy Survey observes…
