radio interferometer

A radio interferometer is a system of two or more radio antennas working together to observe celestial objects. By combining the signals from these antennas, it mimics a much larger telescope, providing higher resolution images of distant cosmic phenomena like stars and galaxies. This technique allows astronomers to see finer details than with individual antennas alone, enabling more precise studies of the universe. The distance between antennas and how their signals are combined determine the level of detail, making interferometers powerful tools for exploring space’s subtle structures.
