📡 Interstellar Communication Link: 2D Star Map

Interactive 2D star map of a deep-space radio or laser link: aim a transmitter from the Sun at nearby stars, then watch signal pulses cross the light-years while the Friis free-space equation and Shannon capacity give received power, SNR and achievable bit rate.
