NASA s Voyager 1 Probe Detects Gentle Rain of Plasma Activity in Interstellar Space
On 5/11/21 at 10:33 AM EDT
Voyager 1 the first man-made object to enter interstellar space continues to detect plasma waves in deep space despite being far, far away from our sun.
Scientists think that interstellar space, which is the unimaginably vast near-vacuum in between stars, is filled with interstellar plasma.
James Cordes, George Feldstein professor of astronomy at Cornell University, said in a statement that interstellar space is like a quiet or gentle rain, and that the activity of our sun a solar flare, for example is like a lighting burst of plasma activity.
Humanity s most distant space probe captures a strange sound
A new paper reveals that the Voyager 1 spacecraft detected a constant hum coming from outside our Solar System.

Voyager 1, humankind s most distant space probe, detected an unusual hum in the data from interstellar space.
The noise is likely produced by interstellar gas.
Further investigation may reveal the hum s exact origins.
Voyager 1, humanity s most faraway spacecraft, has detected an unusual hum coming from outside our solar system. Fourteen billion miles away from Earth, the Voyager s instruments picked up a droning sound that may be caused by plasma (ionized gas) in the vast emptiness of interstellar space. Launched in 1977, the Voyager 1 space probe along with its twin Voyager 2 has been traveling farther and farther into space for over 44 years. It has now breached the edge of our solar system, exiting the heliosphere, t

In emptiness of space, Voyager I 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.
As the craft toils, it has long since zipped past the edge of the solar system through the heliopause – the solar system’s border with interstellar space – into the interstellar medium. Now, its instruments have detected the constant drone of interstellar gas (plasma waves), according to Cornell-led research published May 10 in Nature Astronomy.
Examining data slowly sent back from more than 14 billion miles away, Stella Koch Ocker, a Cornell doctoral student in astronomy, has uncovered the emission. “It’s very faint and monotone, because it is in a narrow frequency bandwidth,” Ocker said. “We’re detecting the faint, persistent hum of interstellar gas.”
