So a slightly more circular shape of galaxies can be seen from our perspective than one student expected. But it turns out that it's actually not a ring when viewed from any other angle, more of a corkscrew.

Then the authors AI generated a "ring in space" and it created a picture of an alien structure, and they use that for the story picture.

This is such a a non-story that nobody would even read aside from other cosmological researchers except for that completely misleading picture paired with the headline.
