Stellar collision triggers supernova explosion

Astronomers have found dramatic evidence that a black hole or neutron star spiraled its way into the core of a companion star and caused that companion to explode as a supernova. The astronomers were tipped off by data from ...

Researchers simulate compact fusion power plant concept

Fusion power plants use magnetic fields to hold a ball of current-carrying gas (called a plasma). This creates a miniature sun that generates energy through nuclear fusion. The Compact Advanced Tokamak (CAT) concept uses ...

Magnet milestones move distant nuclear fusion dream closer

Teams working on two continents have marked similar milestones in their respective efforts to tap an energy source key to the fight against climate change: They've each produced very impressive magnets.

Negative triangularity—a positive for tokamak fusion reactors

Tokamak devices use strong magnetic fields to confine and to shape the plasma that contains the fuel that achieves fusion. The shape of the plasma affects the ease or difficulty of achieving a viable fusion power source. ...
