How it spread

Trace the origin

The reveal was synchronized across six press conferences: all began at 13:00 UTC and unveiled the image at 13:07. A single recognizable orange ring then became shared raw material for jokes, while Bouman’s reaction photo gave the collaboration a human entry point.

Documented milestone; not a measured attention peak.
