Apochromatic X-ray focusing

A team of scientists from the Paul Scherrer Institut, the University of Basel and DESY have demonstrated the first-ever realization of apochromatic X-ray focusing using a tailored combination of a refractive lens and a Fresnel ...

Hubble captures light-bending galaxy cluster eMACS J1823.1+7822

A vast galaxy cluster lurks in the center of this image from the NASA/ESA Hubble Space Telescope. Like a submerged sea monster causing waves on the surface, this cosmic leviathan can be identified by the distortions in spacetime ...

Scallop eyes as inspiration for new microscope objectives

Neuroscientists at the University of Zurich have developed innovative objectives for light microscopy by using mirrors to produce images. Their design finds correspondence in mirror telescopes used in astronomy on the one ...

Hubble observes gravitational lens of a massive galaxy cluster

A massive galaxy cluster in the constellation Cetus dominates the center of this image from the NASA/ESA Hubble Space Telescope. This image is populated with a serene collection of elliptical and spiral galaxies, but galaxies ...
