Among them, a fantastic improvement of the sharpness of astronomical images, obtained with ground based optical telescopes, has been the result of two revolutions: adaptive optics and optical interferometry. Written for a general audience, interwoven with fascinating details about the evolution of vision and optics, this book tells a personal story of these revolutions in observational astronomy, born two centuries ago and blossoming in the past fifty years. With the construction of the Very Large Telescope in Chile, Europe played a leading role where young scientists, joining creative astronomers and engineers, have developed a superb creativity. Today, incredibly sharp images of exoplanetary systems and black hole environments are obtained and reveal new questions about Earth-like objects or fundamental physics. The author has been one of the actors of this adventure. His first-hand testimony is opening the future to new horizons. 410 0$aAstronomers' universe. 606 $aImaging systems in astronomy$xHistory 606 $aAstronomical instruments$xHistory 615 0$aImaging systems in astronomy$xHistory. 615 0$aAstronomical instruments$xHistory. 676 $a522 700 $aLe?na$b Pierre$052155 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910427677903321 996 $aAstronomy's quest for sharp images$91984745 997 $aUNINA
