We cannot see any exoplanets from any galaxies outside our own. All the exoplanets we’ve found are in nearby areas of the Milky Way.

When we do detect exoplanets, they tend to be large and orbiting close to their parent star. We cannot see them directly, but instead we observe their effect on the star, either by watching it wobble slightly as the two orbit their common center of mass, or by watching the star dim slightly as the planet passes in front. Neither of these methods is applicable to a planet in our own system orbiting far out from the Sun.
