The Voyager one spaceship, which recently grew to be the very first man-designed object to leave our solar system, has transmitted peculiar, sharp pitched shrieks and squeals from past the void.
The noises, described by a few as the ‘howl’ and by some others as a ‘scream’, were recorded at a expanse of 12 Billion miles from our sun.
The ‘shrieks’ detected by Voyager’s instruments are actually plasma waves. The high-pitched signal emitted by them are impossible to hear in outer space, but within the range of detection through the Human ear.
A spokesperson for NASA remarked, “The soundtrack reproduces the amplitude and frequency of these plasma waves as “heard” by Voyager one. The waves detected through the instrument antennas may be merely augmented and played through a speaker.”
Ed Stone, a Voyager Project scientist based in the California Institute of Technology said that, “The 36-year old probe will now be sailing in unfamiliar waters of a new cosmic sea and they have brought us alongside for the journey.”
Previously this year, Voyager one’s devices indicated that spacecraft had either left, or was going to leave, the solar system. However, nobody could give an exact figure regarding how long it may take. The transmission of those bizarre sounds has helped scientists to work out, once and for all, that Voyager 1 has certainly left our space for pastures unknown.
The Voyager spacecraft was initially launched in 1977 and, ever since that point, it has traversed billions of miles throughout our solar system. It’s now so far from earth that communication messages, including the creepy shrieks of interstellar outer space, take approximately seventeen hours to turn up at NASA head office.
Voyager 1 is supposed to carry on transmitting until a short time in 2020.
The sounds from outside the boundaries of our solar system are a fascinating way to mark our species historic entry into interstellar deep space.
