This newly discovered Exomoon, which is highly volcanically active, would indicate a young age. Remember, IF a planet is volcanic and is "billions" of years old, or even just "millions"- theoretically it should no longer be volcanically active....

"Astronomers have found evidence for a possible exomoon orbiting a gas giant planet 550 light-years away. If they’re interpreting the evidence correctly, this moon would be a place of destruction,
even more volcanically active than Jupiter’s famous volcanic moon, Io.
Astronomers may have discovered a “hyper-volcanic” exomoon – an extreme version of Jupiter’s moon Io – orbiting a distant planet. A new study suggests that this possible moon, 550 light-years away, is even more volcanically active than Io, the most volcanically active body in our own solar system. An amazing discovery, if true."
