Observations Ranging is a technique used in radio astronomy to measure the distance and velocity of objects in space. It involves the observation of a simultaneous burst of radio emission from a distant astronomical object, such as a supernova or a pulsar, from multiple locations on the Earth's surface. By measuring the time difference between the arrival of the signals at each location, astronomers can calculate the distance and velocity of the object.
The technique was first used in the 1960s by a team of astronomers led by Thomas Gold,
Observations Ranging has several advantages over other methods for determining the distance and velocity of objects
Today, Observations Ranging is used in a variety of applications, including the study of supernovae, pulsars,
