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 ...

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 ...

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 ...

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 ...

To harness the forces that power the Sun to produce substantial clean energy on Earth, researchers heat fuel to such a high temperature that atoms melt into electrons and nuclei to form a hot, gaseous ...

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.

Plasma waves are a critical element to understanding the many mysteries of the gas giant’s turbulent, magnetically powerful atmosphere, the researchers say. Reading time 3 minutes Since entering ...

Voyager 1 composite plasma wave spectrum. Top: Frequency-time dynamic spectrum showing all of the Voyager 1 PWS wideband data available since Voyager 1 crossed the heliopause on August 25, 2012. The ...

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 ...
