The Voyager one spaceship, which recently evolved into the very first man-designed entity to depart our sun system, has transmitted creepy, high pitched shrieks and squeals from past the void.
The noises, described by several as a ‘howl’ and by some others as a ‘scream’, were recorded from a distance of twelve Billion miles from our sun.
The ‘shrieks’ detected by Voyager’s instruments are indeed plasma waves. The high-pitched noises emitted by them are impossible to hear in outer space, but within the range of detection by Human ear.
A voice for NASA remarked, “The soundtrack reproduces the amplitude and frequency of those plasma waves as “heard” by Voyager one. The waves detected through the instrument antennas may be just augmented and played through a speaker.”
Ed Stone, a Voyager Project scientist based at the California Institute of Technology stated that, “The 36-year old probe is sailing in unexplored waters of a new cosmic ocean and they have brought us alongside on the journey.”
Earlier this year, Voyager 1’s instruments indicated this craft had left, or was going to depart, the solar system. However, nobody could give a particular figure regarding how long it may take. The transmission of those peculiar noises has aided scientists to determine, once and for all, that Voyager one has indeed left our space for pastures unknown.
The Voyager craft was initially launched in 1977 and, since that point, it’s travelled billions of miles throughout our solar system. It’s now so far away from the planet that radio messages, including the creepy shrieks of interstellar deep space, take about 17 hours to be delivered at NASA H.Q..
Voyager 1 is expected to keep on transmitting until sometime in 2020.
The sounds from outside the limits of the solar system are a desirable method to mark our species historic access into interstellar deep space.
