Description

In 1977, the Big Ear radio telescope at Ohio State University received a signal so anomalous that the astronomer reviewing the data circled it and wrote "Wow!" in the margin. It has never been explained. The Unknown Origin Signal t-shirt operates in that same space — the moment between reception and understanding, when the data is real but the source is not yet known. Encoded script runs the outer ring. The craft sits at the centre of a transmission that arrived before we had the language to read it. The signal was received. The origin remains unknown.
