dc.description.abstractPulsar stars act like simple radio stations consisting of a rotating two pole electromagnet. They behave like interstellar beacons radiating electromagnetic pulses in the microwave band.The interstellar radiation reaches our planet after traveling distances of the order of thousands of light-years and after having interacted with the interstellar plasma. By studying the transmission and dispersion of these waves by means of Maxwell and Newton equations, the distance to Pulsars can be determined as well as other interesting characteristics.The interaction of our ionosphere with these radiofrequencies can be significant. The following article shows how radiofrequency waves lower than 9MGHz, and AM frequencies inclusive, are reflected by the earth ionosphere, and how the distance to Pulsars can be calculated by means of frequency dispersion and also how the ionic concentration in space can be calculated. Space is not empty, as stated in many books. As a minimun there can be as many as 30,000 electrons per cubic meter and other particles, dust, and neutral and ionized hydrogen. Space can be consider as a low density plasma.en_US
