I just read that the large radio telescope in Arecibo, Puerto Rico can detect a signal that lays down only one picowatt of power over the entire earth. Out of curiosity, I imagined that there is a twin Earth planet somewhere in space and wanted to calculate the maximum distance of detection based on the parameters of the telescope.
Does anyone know what human-made source currently puts out the most powerful signal and a rough estimate of its power?
Thanks.
