The Big Bang
Description: An animation of the explosive beginnings of the Universe following the evolution of the Universe from it's rapid expansion from a very dense, hot state to the formation of stars and galaxies.

Effects of Dark Energy
Description: This animation shows the expansion history of the Universe by modeling the Universe as a two-dimensional grid of galaxies. The Big Bang, shown as a flash of light, is immediately followed by rapid expansion of the Universe. This expansion then slows down because of the gravitational attraction of the matter in the Universe. As the Universe expands, the repulsive effects of dark energy become important, causing the expansion to accelerate. The size of the deceleration and acceleration has been exaggerated.

Timeline of the Universe
Description: Diagram showing a representation of the evolution of the universe over 13.7 billion years. The far left depicts the earliest moment we can now probe, when a period of "inflation" produced a burst of exponential growth in the universe. For the next several billion years, the expansion of the universe gradually slowed down as the matter in the universe pulled on itself via gravity. More recently, the expansion has begun to speed up again as the repulsive effects of dark energy have come to dominate the expansion of the universe.
