It’s a media object relating to the Kureze effect and (mainly) the Ingress storyline. You can just delete it if you don’t follow said storyline.
Can someone explain what gello and the Ghostbusters clue in news has to do with storyline???
It was from the Kureze effect. The image was revealed by Kureze after the Phase conclusion, and another Kureze message was in the in-game news. Ergo, storyline related.
