The image is a photograph of a sign that reads "Astronomy: Mesopotamians used the sun, the moon, and the stars to establish a calendar". The sign is displayed in a museum or exhibition space with a wooden frame and a white background. The text is written in black font and is centered on the sign. Below the text, there is a list of dates and events related to Mesopotamia, such as the birth of the sun and the moon. The dates are written in a smaller font size and are arranged in a grid-like pattern.

At the top of the sign, there are illustrations of planets, stars, and other celestial bodies. The sign also includes a legend that explains the meaning of each date and event. The background of the image is blurred, but it appears to be an indoor space with other exhibits and artifacts visible.
