This infographic is done in shades of blue and white. At the top left is the title: “History of the Universe.” Below that is a cone with graphics representing different stages of cosmic history within eight evenly spaced ovals. Below the cone is text connected to each oval indicating time since the beginning of the universe, the name of the cosmic era, and a brief description. The first oval on the left is filled with blobs, and the associated text reads: 10 to the negative 32 seconds, Inflation, and Initial expansion. Moving right, the next oval is filled with light (represented as squiggles), protons, and neutrons. The text below reads: one microsecond; first particles; and neutrons, protons, and electrons form. The next oval is filled with light (squiggles) and atomic nuclei. The text below reads: three minutes; first nuclei; and helium and hydrogen form. The next oval is filled with light (squiggles) and atoms. The text below reads: 380,000 years; first light; and the first atoms form. The next oval is filled with transparent areas of blue representing gas with a few dots representing stars. The text below reads: 200 million years; first stars; and gas and dust condense into stars. The next oval is filled with tightly packed galaxies with some transparent areas representing gas. The text below reads: 400 million years; galaxies and dark matter; and galaxies form in dark matter cradles. The next oval is filled with galaxies that have moved apart with stars in between. The text below reads: 10 billion years; dark energy; and expansion accelerates. The last oval is filled with galaxies that have moved far apart with stars in between. The text below reads: 13.8 billion years; today; and humans observe the universe.

A graphic shows a central black circle outlined in white. This circle is surrounded by a black ring which is surrounded by a light blue ring which then fades outward into bright and then dark and diffuse purple. Across the middle of the image is a light blue line that gives the appearance of a ring around the circular object.
