#TIL The sun is a huge high-gain antenna due to gravitational lensing. A hypothetical Voyager 3 can supposedly reach its >= 550 AU focal point in 50 years, which would allow a high-resolution optical scan of an exoplanet, or to receive alien livestreams from Alpha Centauri at 10 Mbps/watt with just a 1-meter telescope.
