Re-Ionization Era

Artist’s concept of a scene during the Era of Reionization: Scattered across the black background are many small points of orange-yellow light. In the center is the largest orange-yellow orb, with its brightness illuminating its close surroundings. Purple clumpy material stretches across the scene, resembling a tangled spiderweb. It is densest surrounding the central orange-yellow light and becomes sparser toward the edges of the frame.

A visualization of galaxies–composed of gas, stars and dark matter–colliding and form filaments in the large-scale universe, providing a view of the Cosmic Web.
