[Anthony Garofalo] has made a fancier plasma speaker. Not content with a simple spark, he uses a plasma vortex. To make the vortex, the spark gap is swapped out for an electrode placed in the centre ...

Video from NASA telescopes shows a filament on the sun breaking off and swirling around its north pole. A solar physicist called the polar vortex a "scientific curiosity" and hasn't seen anything like ...

The structure is believed to be around 60,000-miles-tall. This is the latest in a string of stunning solar events as our sun nears a peak of activity. A stunning solar "waterfall" has been spotted on ...

You’ve heard of the polar vortex, but how about a solar polar vortex? Scientists and the public alike are in awe over a bizarre video that emerged of a vaporous-looking eddy of solar plasma swirling ...

We’re used to loudspeakers as circular components with a paper cone and a big magnet inside which is suspended a coil that is connected to our audio amplifier. But moving-coil speakers are not the ...

Drexel researchers have developed technology to help eliminate a chemical compound, originally used in nonstick pans, waterproofing and fire fighting foam, that has become a persistent contaminant in ...

The high-energy radiation that carries orbit angular momentum has become an extremely important tool to investigate the angular momentum-related physics in the microworld. But the generation and ...

On August 31, 2012 a long filament of solar material that had been hovering in the sun's atmosphere, the corona, erupted out into space at 4:36 p.m. EDT. Source - NASA Goddard Space Flight Center. CC ...

Hall thrusters are used in earth-orbiting satellites and show promise to propel robotic spacecraft long distances, and the plasma ejected from the exhaust end of the thruster can deliver great speeds.

Researchers from Drexel University have found a way to destroy stubbornly resilient toxic compounds, ominously dubbed “forever chemicals,” that have contaminated the drinking water of millions across ...
