Ralph Spencer

Ralph Spencer is a Professor Emeritus of Radio Astronomy at the University of Manchester in the UK, with a distinguished career in the study of radio waves from celestial objects. He has contributed to the understanding of satellite communications and the effects of space debris on astronomical observations. Recently, Spencer has voiced his agreement with findings related to the detection of radio signals from old satellites, underscoring the need for astronomers to distinguish between astrophysical sources and signals from man-made objects.
