Новый удивительный прибор позволяет взглянуть за горизонт Черной дыры

Animation of the path that an incoming light ray traces through the GRAVITY instrument. Note the intricate design and complex interaction of the various components for the four telescopes. For interferometry to work, the light paths have to be superposed with a precision of a fraction of the wavelength – less than 1 micrometer. More information and download options: Credit: MPE
