Hey dude,
Nonetheless, the most distant known planets are SWEEPS-11 and SWEEPS-04, located in Sagittarius, approximately 27,710 light-years from the Sun, while the Milky Way is between 100,000 and 180,000 light years in diameter. This means that even galactic planets located farther than that distance have not been detected.

Intergalactic gas is so tenuous that it emits no light of its own. ... Instead astronomers study it indirectly by observing how it selectively absorbs the light coming from faraway sources known as quasars.
