German scientists have successfully created the first helium plasma out of a "stellarator" called Wendelstein 7-X, or W7-X.

Wendelstein 7-X took nine years for the scientists at Max Planck for Plasma Physics in Greifswald to create, and the preparations for the first experimental test took over a year.

"Stellarators" are used to mimic a process similar to what the sun does - nuclear fusion of atoms to generate energy, which, when harnessed to full potential, can provide limitless, safe and cheaper energy, according to AFP.

As if constructing a "stellarator" was not enough of a challenge in the plasma physics community, the W7-X had a major setback from 2003 to 2007 because the contracted manufacturer went out of business, almost bringing down the project, too, according to Business Insider.

That is why, when W7-X successfully produced its first plasma, the Max Planck Institute for Plasma Physics proudly tweeted the achievement.

"We're very satisfied. Everything went according to plan," said Hans-Stephan Bosch, a scientist involved in machine operation, according to The International Business Times.

The next step for the team is to extend the duration of plasma discharges, as well as figure out a way to heat the helium plasmas using microwaves.
