A research team of fusion scientists succeeded in proving that ions can be heated by plasma oscillations driven by high-energy particles. This has been confirmed by performing a large-scale simulation ...

Most people know about solids, liquids, and gases as the main three states of matter, but a fourth state of matter exists as well. Plasma—also known as ionized gas—is the most abundant, observable ...

The results obtained from a large number of probe measurements of plasma-beam oscillations and of plasma electron temperatures and concentrations in some low pressure hot cathode inhomogeneous ...

Hall thrusters utilise electric propulsion through the ionisation and acceleration of plasma under crossed electric and magnetic fields, offering efficient and reliable performance for spacecraft.

Voyager 1—the most distant human-made object—has made yet another remarkable discovery having to do with interstellar space. It’s steady, persistent, and long-lasting: a low-frequency hum that’s ...

To harness the forces that power the Sun, researchers heat fuel to such a high temperature that atoms melt into electrons and nuclei to form a hot, gaseous soup called plasma. The plasma can rip ...

A weak but persistent signal from the Voyager 1 spacecraft at first seemed like a fluke to Cornell University Ph.D. candidate Stella Koch Ocker. “I was literally just kind of staring at a plot, and I ...

Niek van Hulst heads up the Molecular Nano-Photonics group at the Institute of Photonic Sciences (ICFO) in Barcelona, Spain. His current research projects include optical field enhancement and probing ...

This rendering provided by NASA shows Voyager 1. NASA has nailed a thruster test on Voyager 1, a spacecraft 13 billion miles away. Last week, ground controllers sent commands to fire backup thrusters ...

Voyager 1 – one of two sibling NASA spacecraft launched 44 years ago and now the most distant human-made object in space – still works and zooms toward infinity. The craft has long since zipped past ...
