This means radio telescope arrays can see incredibly smallĭetails. That have the same resolution as if they had a single telescope as big as the distanceīetween the two telescopes. However, space-based radio observatoriesĬomplement Earth-bound radio telescopes in some important ways.Ī special technique used in radio astronomy is called "interferometry." RadioĪstronomers can combine data from two telescopes that are very far apart and create images In fact, radio telescopes can observe even on cloudy days. Radio waves can make it through the Earth's atmosphere without significant obstacles. The Spektr-R spacecraft with an imagined radio antenna that isĬreated by combining Spektr-R's data with that of Earth-bound radio Try your hand at building an observatory with the Build It Yourself: Satellite!
