Karl Jansky pioneered the study of these things and lends his name to a unit of flux density most commonly used to measure these things.
Karl Jansky pioneered the study of these things and lends his name to a unit of flux density most commonly used to measure these things. The existence of Jupiter's magnetosphere was first suggested by the "decametric emission", which was one of these things. Because telescopes that detect them have very low resolving power, technique like VLBI are used, like at the Very Large Array. 3C 273 was first detected by emissions of this type, leading to its designation as a "quasar". The Arecibo dish telescope collects data in this band of the EM spectrum. For 10 points, name this segment of the electromagnetic spectrum that has longer wavelengths than microwaves.
