Satellite Constellations and Radio Astronomy

In the San Augustine Plains of central New Mexico, 27 radio telescopes stand tall, operating nearly 24 hours, 7 days a week capturing extremely weak signals emitted from all over the Universe. This flat and vast land, once a seabed, sits at an altitude of 7,000 feet and is surrounded by 360 degrees of mountains. Despite the ideal conditions of this location, "listening" to these faint radio emissions is becoming increasingly difficult as the Earth becomes "noisier" in the same direction in which these dish antennas are pointed, the sky. At ground level, the National Radio Astronomy Observatory's (NRAO) Very Large Array keeps a continuous live monitoring station dedicated for receiving Wi-Fi and Bluetooth radio transmissions for visitors' cellphones and other electronic devices...
