Voyager 1 Becomes the First Man-Made Object in Interstellar Space

Today, Voyager 1 passed into interstellar space, the space outside of the bulk of our sun’s affects. It is the first man-made object ever to make it that far into space.

Mankind has just made a great leap by sticking its toe in the water of long-distance space exploration.

Scientists began to notice that the materials, namely the plasma, around the probe began to change in 2004 and they suspected it was coming close to interstellar space.

Voyager Captures Sounds of Interstellar SpaceNASA's Voyager 1 spacecraft captured these sounds of interstellar space. Voyager 1's plasma wave instrument detected the vibrations of dense interstellar plasma, or ionized gas, from October to November 2012 and April to May 2013. The graphic shows the frequency of the waves, which indicate the density of the plasma. Colors indicate the intensity of the waves, or how "loud" they are. Red indicates the loudest waves and blue indicates the weakest. The soundtrack reproduces the amplitude and frequency of the plasma waves as "heard" by Voyager 1. The waves detected by the instrument antennas can be simply amplified and played through a speaker. These frequencies are within the range heard by human ears. Scientists noticed that each occurrence involved a rising tone. The dashed line indicates that the rising tones follow the same slope. This means a continuously increasing density. When scientists extrapolated this line even further back in time (not shown), they deduced that Voyager 1 first encountered interstellar plasma in August 2012. The Voyager spacecraft were built and continue to be operated by NASA's Jet Propulsion Laboratory, in Pasadena, Calif. Caltech manages JPL for NASA. The Voyager missions are a part of NASA's Heliophysics System Observatory, sponsored by the Heliophysics Division of the Science Mission Directorate at NASA Headquarters in Washington.

Voyager 1 was launched in 1977 and since then it has traveled to an astounding distance of 12 billion miles away from our sun, according to NASA. The Earth is almost 93 million miles from the sun. Although the probe is entering interstellar space, it has not yet left our solar system, it is in an zone where the two spheres overlap as you can see below.

NASA is celebrating the far-out triumph with a ringtone made from the sounds collected by Voyager 1. The inter-stellar probe is also hosting an AMA on Reddit at 6 p.m. EST.
