Scientists using NASA's Hubble Space Telescope
just found intriguing evidence of the first possible exomoon.
Exomoons are moons orbiting planets outside our solar system.
The Kepler spacecraft showed the first hints
of a moon orbiting exoplanet Kepler-1625b.
Now Hubble has also observed a transit of the planet
with a signature that appears to be a moon.

If truly a moon, it would be the size of Neptune
and its planet is bigger than Jupiter.
More Hubble observations will confirm what this truly is.
