Light my fire: How to start up fusion devices every time

How do you start a fusion reaction, the process that lights the sun and stars, on Earth? Like lighting a match to start a fire, you first produce plasma, the state of matter composed of free electrons and atomic nuclei that ...

Image: Hubble views star nearing its end

This image from the NASA/ESA Hubble Space Telescope shows NGC 5307, a planetary nebula that lies about 10,000 light-years from Earth. It can be seen in the constellation Centaurus (the Centaur), which can be seen primarily ...

New technique could streamline design of intricate fusion device

Stellarators, twisty machines that house fusion reactions, rely on complex magnetic coils that are challenging to design and build. Now, a physicist at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory ...

Improving the magnetic bottle that controls fusion power on Earth

Scientists who use magnetic fields to bottle up and control on Earth the fusion reactions that power the sun and stars must correct any errors in the shape of the fields that contain the reactions. Such errors produce deviations ...
