Radio astronomy opens an invisible window on the cosmos, revealing phenomena hidden from optical telescopes — pulsars, quasars, cosmic microwave background radiation, and the cold hydrogen that traces galactic structure. Since Karl Jansky's accidental discovery of cosmic radio emission in 1932, the field has driven some of the greatest discoveries in astrophysics.
These simulations let you explore radio telescope beam patterns, combine baselines for interferometric resolution, analyze pulsar timing residuals, visualize the radio spectrum, and synthesize aperture images — all with physically grounded models and interactive parameter control.
