Match the description to the correct astronomical term. Makes up about three percent of the total matter budget within a galaxy cluster, consisting of stars and galaxies. The process through which small structures like halos form first, followed by larger structures through mergers and accumulation. Indicates that most of the matter in our galaxy resides beyond the visible light we can see. A project that systematically mapped the universe by marking galaxies as white dots, allowing for a 3D arrangement and simulation of a fly-through of the universe. Long, thin stretches of matter that connect large structures in the universe, such as galaxy clusters, forming a cosmic web. The force responsible for pulling matter together, playing a central role in the formation of cosmic structures. Consists of hot, dense, ionized gas that emits at X-ray wavelengths, representing about twelve percent of a cluster's mass. Dense regions surrounding galaxies, composed primarily of dark matter, approximately ten times larger than the galaxy it surrounds. Causes light from background objects to bend, sometimes into beautiful arc-like shapes
