The Hubble and Kepler space telescopes found evidence for what could be a giant moon accompanying a gas-giant planet that orbits the star Kepler-1625, located 8,000 light-years away in the constellation Cygnus. News release: https://go.nasa.gov/2yc4sCY
The moon may be as big as Neptune and it orbits a planet several times more massive than Jupiter.
