Topic description and stories

A new map of the dark matter made by the Atacama Cosmology Telescope. ̽��ֱ��orange regions show where there is more mass; purple where there is less. ̽��ֱ��typical features are hundreds of millions of light years across. ̽��ֱ��grey/white shows where contaminating light from dust in our Milky Way galaxy, measured by the Planck satellite, obscures a deeper view.
