Why do astronomers struggle to detect individual planets in the Andromeda Galaxy?
Answer
Stars are packed too closely together, causing their light to blend
From our perspective on Earth, the stars in the Andromeda Galaxy are so densely packed that their light overlaps, creating a diffuse glow rather than distinct points of light. This clustering prevents telescopes from resolving the tiny, non-luminous light signals or dips in brightness that would indicate the presence of a planet orbiting a specific star.
