NASA’s Voyager 2 Enters The Interstellar Space

NASA’s Voyager 2 spacecraft has crossed the elusive boundary that marks the edge of the Sun’s realm and the start of interstellar space. Researchers Bill Kurth and Don Gurnett confirmed that on November 5, 2018, at the University of Iowa. The team analyzed the plasma density of the plasma wave detector on the spacecraft and reported a marked increase in its density, which indicates that Voyager 2 now lies in a cool, higher-density of the interstellar medium (ISM). Voyager 2 is now the second human object to cross the region of the sun’s influence, after the Voyager 1.
