The plasma wave system on the National Aeronautics and Space Administration (NASA) Voyager 1 spacecraft has detected a roaring sound in the galaxy. Scientists believe that this sound is caused by a small amount of gas in space. This dim monotonous hum refers to the background noise that is present in the expansion between the star systems. These series of plasma waves detected at short frequency radio frequencies have been detected since 2017.
Launched by NASA 44 years ago on 5 September 1977, Voyager 1 Is part of the Voyager project to study the outer solar system. It was launched 16 days after the launch of its dual, Voyager 2. Voyager 1 went into galaxy on August 2012 and continues to collect data. It provides scientists with observations of “truly unnamed territory” and helps to understand “the nature of energy and radiation in space”.
As stated in it Cornell Chronicle, Published research Natural astronomy May 10 allows scientists to determine how the galaxy interacts.
The galaxy has turbulent waves and crashing waves give us clues about its density. Features such as the shape of the heliosphere, star formation, and our location in the galaxy are determined by the density of the galaxy.
Speaking about their findings, Stella Koch Ocker, the study’s lead author, said there was less activity in galaxy gas than scientists had previously thought. Stella called this research a testament to Voyager 1. The spacecraft is the gift of engineering to science. Stella holds a PhD in Astronomy from Cornell University.
Shami Chatterjee, another researcher involved in the study, said Voyager returns details regardless of what the sun does. Now, he said, to measure galactic plasma, they do not need a lucky event related to the sun.
