Schematic comparison of carrier injection through a) 1 + 2 and b) 2 + 3 quantum interference within a semiconductor. The higher-order 2 + 3 process concentrates carriers into a narrower range of momentum-space directions and produces a more directional photocurrent.
University of Michigan researchers use phase- and polarization-controlled two-color laser fields to generate a photocurrent within a semiconductor and control the direction in...

Satellites crossing the night sky above the northern Atacama Desert in Chile during an hour. It’s a stack of a time-lapse video taken on October 15, 2025, about two hours after sunset. Some streaks are caused by planes, easily identified by blinking-colored lights, but most trails are from satellites. In the foreground is the dome of ESO’s Extremely Large Telescope, the world’s largest optical/infrared telescope, currently under construction atop Cerro Armazones. Behind it are the lasers of ESO’s Very Large Telescope (VLT) at Paranal Observatory, 22 km away.

Rubin’s 1.7-gigapixel image of a field of stars within the constellation Lupus gives us an unprecedented view of the Universe. Faint, glowing clouds spread across this image are galactic cirrus—clouds of interstellar gas and dust found in the foreground of the Milky Way.
