Scientists have unveiled a new way to capture ultra-sharp optical images without lenses or painstaking alignment. The ...

Optical aberration theory remains a fundamental component in the design and operation of space telescopes. With increasingly ambitious astronomical missions and the demand for high-resolution imaging, ...

“They can move in steps that are a fraction of a wavelength of light, or about 1/10,000th the diameter of a human hair,” explained Lee Feinberg, optical telescope element manager of the NASA James ...

IIIF provides researchers rich metadata and media viewing options for comparison of works across cultural heritage collections. Visit the IIIF page to learn more. The optical device which the ...

Conventional telescopes are limited in detecting low-surface-brightness (LSB) structures, which are essential for studying galaxy evolution. Now, researchers have developed a new telescope system ...
