Researchers argue back and forth about whether we’ve spotted an exomoon

From Ars Technica:
"In 2017, the astronomy world was abuzz at the announcement that exoplanet Kepler-1625b potentially had its own moon—an exomoon. This was the first hint anyone had seen of an exomoon, and was followed five years later by another candidate around the planet Kepler-1708b.
...
The most recent paper on the topic, published by astronomers in Germany, has come to the conclusion that the exomoon candidates around Kepler-1625b and Kepler-1708b are unlikely. Previous work has also cast doubt on the exomoon candidate around Kepler-1625b."

Thanks Stephen. I suppose this means exomoons have not been ruled out, just that we have been unable to detect them.
