Sunlight is passed through a crystal that splits each photon into two entangled halves. Their invisible link allows imaging where ordinary optics are blind: in fog, under murky water, in near-total darkness. Previously, only lasers could do this—bulky and expensive. Now, daylight can be the source,

New data from the JWST telescope on galaxy NGC 4696 in the Centaurus cluster have for the first time traced the kinematic connection between large-scale filaments and a compact circumnuclear disk with a radius of about 120 parsecs. The S-shaped structure, familiar from Hubble images, turned out to b

Why does the ratio of X-ray brightness to H-alpha line emission in diverse systems—from galactic winds to jellyfish—stubbornly hover around three? Astonishingly, H-alpha arises from cold gas (10,000 K), while X-rays come from plasma heated to millions of degrees. Three-dimensional simulations have c
