NASA’s Voyager 1 spacecraft has detected a strange humming sound in interstellar space that scientists are dubbing “persistent hum.” This noise is being picked up by its plasma wave instrument and caused by interactions between the interstellar medium and energy emitted by the spacecraft.

Voyager 1 was launched in 1977 and has been traversing interstellar space since 2012, becoming the first human-made object to leave our solar system. Equipped with various scientific instruments for studying this environment beyond Earth’s atmosphere, including the plasma wave instrument which detects electromagnetic waves within space.
Voyager 1 has detected a low-level sound with an approximate frequency of 3 kHz. Its source is believed to be the interstellar medium – that space between stars where matter and radiation exists – creating this continuous hum.
Although the sound is imperceptible to human ears, scientists studying interstellar space have made an important discovery. Their finding indicates there may be more activity in interstellar space than previously believed and could provide new insight into the physical processes occurring there.
The discovery of the persistent hum is just the latest in an array of remarkable discoveries made by NASA’s Voyager 1 probe since it became the first human-made object to leave our solar system back in 2012. Since then, it has been sending back data on the interstellar environment.
The discovery of a persistent hum is a reminder of NASA’s incredible Voyager 1 mission and their ongoing exploration of interstellar space. It also serves as evidence for scientific inquiry and discovery, even in remote and inhospitable regions of space.
The Voyager 1 mission has been a remarkable achievement for NASA and the scientific community, providing unprecedented insights into the mysteries of interstellar space.
The persistent hum detected by the spacecraft’s plasma wave instrument adds to a growing body of knowledge about the interstellar medium and the physical processes that occur in this region of space.
It is a reminder of the ongoing importance of space exploration and scientific discovery, and the incredible potential that exists for further exploration and discovery in the vast expanse of the universe.
