The Voyager one spaceship, which only just became the very first man-designed entity to depart our solar system, has transmitted eerie, high pitched shrieks and squeals from beyond the void.
The noises, described by several as the ‘howl’ and by some as a ‘scream’, were recorded from a distance of twelve Billion miles from our sun.
The ‘shrieks’ detected by Voyager’s instruments are actually plasma waves. The high-pitched sound emitted by them are inaudible in the cosmos, but within the range of detection by the Human ear.
A voice for NASA stated, “The soundtrack reproduces the amplitude and frequency of the plasma waves as “heard” by Voyager one. The waves detected by the instrument antennas could be just augmented and trialled in a speaker.”
Ed Stone, a Voyager Project scientist based at the California Institute of Technology said that, “The 36-year old explorer is sailing through unfamiliar waters of a brand new cosmic ocean and they have brought us alongside on the journey.”
Earlier this year, Voyager 1’s instruments indicated that the craft had either left, or was going to leave, the solar system. Yet, nobody could give a definite figure concerning how long it may take. The transmission of those peculiar noises has assisted scientists to determine, once and for all, that Voyager 1 has indeed left our space for pastures unknown.
The Voyager spacecraft was originally launched in 1977 and, since that time, it has traversed billions of miles in our solar system. It’s now so far from the planet that radio messages, including the peculiar shrieks of interstellar outer space, take around seventeen hours to be delivered at NASA head office.
Voyager 1 is expected to carry on transmitting until a short time in 2020.
The noises from beyond the limits of the solar system are a fascinating solution to mark our species historic entry into interstellar deep space.
