Astronomers have uncovered a hidden cosmic web of galaxies and gas by mapping hydrogen light from the early universe.

High-energy lasers can burn drones in the sky like a blowtorch. But they can be stymied by weather, and making them at scale will be a challenge.

Astronomers have created the largest and most detailed 3D map yet of a glowing signal from the early universe, revealing hidden galaxies and gas from 9-11 billion years ago. By analyzing faint ...

Researchers in Hong Kong and the UK have revealed how one species of self-propelling microbes can actively change the path of their swimming motions, depending on how much light they receive.
