Optical systems such as telescopes or cameras have been limited by a phenomenon scientist call the Rayleigh criterion ... effectively limiting the resolution. However, an international research ...

The resolution limit of traditional optical microscopy is set by the Rayleigh criterion: if two features are separated ... struggle to obtain molecular-scale resolution. Microscope images of a square ...

The satellite photos that were being studied were provided by DigitalGlobe. So why not use higher-resolution images? One reason is that hiring a plane to fly over North Korea isn’t particularly ...

Typically, astronomers will get higher resolution images by using a bigger telescope, but the EHT already spans the Earth. Instead, the collaboration observed shorter wavelengths of light ...
