Radio telescopes are used to determine UT. ©bigstockphoto.com/hongee Definition of Universal Time Universal Time is a During a solar day, our planet completes a full rotation around its UT Measured by the Stars Despite being defined as a solar time standard, Universal Time is usually measured by the stars. This ensures a higher degree of accuracy. As Earth spins around its axis, the Sun and other immobile celestial bodies appear to move across the sky. By registering the moment a fixed star passes a location's Modern technology allows us to determine UT with an unprecedented level of accuracy. Procedures like Very Long Base Interferometry (VLBI), where an array of radio telescopes is used to intercept radio signals from distant celestial bodies, such as quasars, achieve a precision of less than 4 milliseconds in relation to TAI. Sidereal Time vs. Solar Time The time measured by the stars is called sidereal time. It is not the same as solar time, so scientists have to mathematically convert their measurements to arrive at UT. Sidereal time reflects the period it takes Earth to complete a full rotation around its axis in relation to a fixed object outside of Earth's orbit around the Sun. Universal Time, on the other hand, refers to the time it takes Earth to complete a full rotation in relation to the Sun. Since the Earth revolves around the Sun, moving in the same direction as it spins around its axis, it has to rotate a little further each day to catch up with the Sun. Thi...
