Telescope

bottom two rows: 100101
<--- 111110X --->
100101 111110 (binary) = 2,430 (decimal)



The last part represents the Arecibo radio telescope with its diameter (2430 multiplied by the wavelength gives 306.18 m). In this case, the number is oriented horizontally, with the least-significant-digit marker to the lower right in the image.


Crop circle

A crop circle containing a modified form of the Arecibo message, referred to as the Arecibo reply, was found near Chilbolton's Observatory, Milk Hill, depicting a grey in place of the human figure
