UK scientists are celebrating landmark progress to using fusion as a clean energy source, after managing to “capture a star” in a specially built machine.

In the first images released from a new high-speed colour camera, it has been possible to picture the equivalent of a star on Earth, created by the glowing pink of plasma .

In the footage, lithium is dropped into the plasma, a state of matter that has reached tens of millions of degrees, causing it to glow red when energised.

Within the company Tokamak Energy’s spherical machine, known as ST40, the matter can be seen turning green before tracing the magnetic field lines, revealing the plasma’s path.

Carried out in partnership with the U.S. Department of Energy (DoE) and the UK Department for Energy Security and Net Zero (DESNZ),
