The field of nuclear fusion has seen some exciting advances of late, with scientists demonstrating how fuels can be heated to the temperatures needed for the necessary reactions to take place. All are ...

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 1960, Theodore H. Maiman's experiment at Hughes Research Laboratories produced the first laser beam using a ruby crystal ...

Whenever light hits an object, some of the light scatters back from the surface of the object. However, if the object is moving extremely fast, and if the light is incredibly intense, strange things ...

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 ...

An experiment at Lawrence Livermore National Laboratory’s (LLNL’s) National Ignition Facility (NIF) appears to have approached fusion ignition as it recreated the extreme temperatures and pressures at ...
