Why astronomers have difficulty looking at distant star ecept?

Astronomers face challenges when observing distant stars primarily due to the vast distances involved, which can lead to light from these stars being faint and redshifted. Additionally, interstellar dust and gas can obscure their visibility, complicating detection. The Earth's atmosphere can also distort observations, making it harder to obtain clear images. However, advancements in technology, such as space telescopes, help mitigate some of these issues.
