Dozens of times over the last decade NASA scientists have launched laser beams at a reflector the size of a paperback novel about 240,000 miles (385,000 kilometers) away from Earth. They announced ...

In a discovery that could reshape how we view and understand the human brain, researchers have successfully passed a laser beam through an entire human head. While it may sound like science fiction, ...

The energy sent is low-intensity, invisible infrared light, which allows ground-based solar projects to generate power even ...

When two black holes merge or two neutron stars collide, gravitational waves can be generated. They spread at the speed of ...

The properties of dense helium (He) — which happens to be a principal constituent of giant gas planets like Jupiter — at thermodynamic conditions between those of condensed matter and high-temperature ...

Lightning rods have been used to guide lightning strikes for centuries, but now scientists have demonstrated something a bit more advanced than a humble metal stick. Beaming a high-powered laser into ...
