A luminous web is visible in the night sky beyond a treeline. Scattered between the nodes of the web is darkness, signifying the presence of dark matter. In the center of the web, the darkness melds to form the shape of a spider.

Something strange and mysterious creeps throughout the cosmos. Scientists call it dark matter. It is scattered in an intricate web that forms the skeleton of our universe. Dark matter is invisible, only revealing its presence by pushing and pulling on objects we can see. NASA’s Roman Space Telescope will investigate its secrets. What will be revealed?
