“I think that the event which, more than anything else, led me to the search for ways of making more powerful radio telescopes, was the recognition, in 1952, that the intense source in the constellation of Cygnus was a distant galaxy—1000 million light years away. This discovery showed that some galaxies were capable of producing radio emission about a million times more intense than that from our own Galaxy or the Andromeda nebula, and the mechanisms responsible were quite unknown. ... [T]he possibilities were so exciting even in 1952 that my colleagues and I set about the task of designing instruments capable of extending the observations to weaker and weaker sources, and of exploring their internal structure.” ScienceUniverseSpacePowerPossibilitySourceStructureAstronomyObservationIntensityMechanismTelescopeMilky WayNobel LaureateLight YearsGalaxiesAndromedaAndromeda GalaxyRadio AstronomyRadio Telescope Author:Martin Ryle
“In 1945 J.A. Ratcliffe ... suggested that I [join his group at Cavendish Laboratory, Cambridge] to start an investigation of the radio emission from the Sun, which had recently been discovered accidentally with radar equipment. ... [B]oth Ratcliffe and Sir Lawrence Bragg, then Cavendish Professor, gave enormous support and encouragement to me. Bragg's own work on X-ray crystallography involved techniques very similar to those we were developing for "aperture synthesis", and he always showed a delighted interest in the way our work progressed.” WayScienceInterestSupportSunGroupsHard WorkInvolvedDiscoveryEncouragementRadioTechniqueEnormousDevelopingProfessorsRaysInvestigationEquipmentLaboratoryDelightedEmissionsRadarSynthesisCambridgeSupport And EncouragementAperture Author:Martin Ryle
