Because the light from the Star is so bright  that it cover-up the dim light
from the planet.

We also know that a Star emit radio wave.
Won't that radio wave from the Star cover-up the radio wave from the planet
where ET live?

With two or more telescopes (optical or radio), and good interferometry between them, the light (or radio waves) from the star can be cancelled to then reveal the weaker light from nearby planets.

This is already being done.


The better question is how much noise a star generates at the frequencies that s@h are searching?

Good luck,
