‘Shrieks’ Heard From Space

The Voyager one spacecraft, which recently evolved into the 1st man-designed object to depart our solar system, has transmitted creepy, sharp pitched shrieks and squeals from outside the void.

The noises, described by some as a ‘howl’ and by others as a ‘scream’, were recorded from a distance of twelve Billion miles from our sun.

The ‘shrieks’ detected by Voyager’s devices are actually plasma waves. The high-pitched sound emitted by them are muted in space, but within the range of detection by Human ear.

A representative for NASA remarked, “The soundtrack reproduces the amplitude and frequency of those plasma waves as “heard” by Voyager 1. The waves detected by the instrument antennas may be just amplified and trialled in a speaker.”

Ed Stone, a Voyager Project scientist based in the California Institute of Technology said that, “The 36-year old probe is now sailing through unexplored waters of a brand new cosmic sea and it’s brought us alongside for the trip.”

Previously this year, Voyager one’s instruments indicated that craft had either left, or was about to depart, the solar system. Then again, no one could give an explicit figure regarding how long it may take. The transmission of those peculiar sounds has helped scientists to determine, once and for all, that Voyager 1 has indeed left our space for pastures unknown.

The Voyager craft was initially launched in 1977 and, ever since that time, it has traversed billions of miles throughout our solar system. It is now so far away from the planet that radio messages, with the peculiar shrieks of interstellar outer space, take about 17 hours to arrive at NASA headquarters.

Voyager 1 is supposed to carry on transmitting until sometime in 2020.

The noises from outside the limits of our solar system are a fascinating way to mark our species historic entry into interstellar outer space.
