The image is a photograph of a metal plaque on a pillar in a museum. The plaque is rectangular in shape and has a textured surface. The text on the plaque reads "Extraterrestrial Radiation" in bold, black letters. Below the text, there is a brief description of the radiation, which states that it is the beginning of the twentieth century. 

The plaque is located in a room with a white wall and a glass window in the background. The room appears to be a museum or exhibition space with a wooden floor and white walls. There are a few people visible in the room, suggesting that the photo was taken in a public space.
