The visibility of galaxies in the night sky has raised questions about why nearby planets are not as easily seen. Observers can see stars and galaxies millions of light-years away, such as those in the Andromeda galaxy, but the visibility of closer celestial objects, like planets, is less clear. Research into the observable universe and the behavior of the universe itself may be shedding light on these phenomena, with some studies suggesting that many galaxies, potentially even those near the Milky Way, remain undiscovered.
