> radio waves from satellites and telescopes beaming out in the plane of our solar system
Surely radio telescopes don't "beam out" radio waves? They receive them. If they are configured to transmit, like the Deep Space Array, they don't beam in the plane of the solar system; they beam at whatever spaceship they are trying to communicate with.
Satellites even less; they have to conserve power, so they don't send radio waves into outer space. Their antennae point at the Earth.
Also, the sentence containing that fragment has no main verb, so I had to read it several times to figure out what it meant.
