In the emptiness of space, Voyager 1 detects plasma 'hum'
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.

Billions of years ago, in the center of a galaxy cluster far, far away (15 billion light-years, to be exact), a black hole spewed out jets of plasma. As the plasma rushed out of the black hole, it pushed away material, creating ...

Since the early 1970s, orbiting satellites have picked up on noise-like plasma waves very close to the Earth's magnetic field equator. This "equatorial noise," as it was then named, seemed to be an unruly mess of electric ...

(Phys.org) —NASA's Voyager 1 spacecraft has experienced a new "tsunami wave" from the sun as it sails through interstellar space. Such waves are what led scientists to the conclusion, in the fall of 2013, that Voyager had ...
