NASA’s Voyager 1 also detects a faint monotone hum beyond our solar system by Jake Pearson

Said NASA’s Voyager 1, the longest spacecraft on Earth Farewell to the Solar System About a decade ago, an interstellar spacecraft passed through an invisible door 11 billion miles from Earth. After that, it travels another 3 billion miles, still sending home data, which allows scientists to search for space between stars. In a paper Published Monday in the journal Nature Astronomy, The researchers examined the information that Voyager 1’s plasma wave system found during its voyage, but especially after it crossed the boundary of the Solar System.
The sound is like a single tone that, over time, changes. The way the frequency moves around as Voyager 1 travels further can tell researchers how the density of the interstellar medium is changing. The hum could also help researchers understand the density of the space between stars. There has never been an opportunity to track and evaluate this kind of data. Cornell research scientist Shami Chatterjee, who co-authored a study on the new sound with Ocker, described the data as the spacecraft saying: “Here’s the density I’m swimming through right now. And here it is now. And here it is now. And here it is now.”

Voyager 1 has struggled past the edge of the solar system and is the boundary between the solar system and the interstellar space.
