Why do astronomers find it difficult to locate extrasoler plants with telescopes?

Astronomers find it challenging to locate exoplanets because these distant worlds are often overshadowed by their host stars, making them difficult to detect. Additionally, the vast distances involved mean that the light from exoplanets is incredibly faint compared to the brightness of stars. Techniques like transit photometry and radial velocity can help, but they require precise measurements and long observation times to identify the subtle signals indicative of planets. Lastly, the sheer number of stars and the complexity of their environments complicate the search further.
