It is official, finally NASA has confirmed that Voyager 1 spacecraft has left the solar system and reached the interstellar space, some 12 billion miles (19 billion km) from our sun.
NASA’s Voyager 1 spacecraft officially is the first human-made object to venture into interstellar space. New and unexpected data indicate Voyager 1 has been traveling for about one year through plasma, or ionized gas, present in the space between stars.
The Voyager 1 spacecraft has left our solar system, marking a new milestone for the satellite, which was launched 36 years ago. NASA confirmed that the spacecraft had crossed the frontier, becoming the first man-made object to ever punch through the solar system and enter interstellar space. It is now about 19 billion kilometres from our sun. After analyzing Voyager 1’s data that is continuously sent back to Earth, NASA determined that the spacecraft likely left the heliosphere on Aug. 25, 2012.
The data acquired by NASA’s Voyager 1 spacecraft as it left the Solar System has been converted into an audio file. This is the sound of the thin gas made up of particles that exist in the space between the stars. It was recorded over several months (October 2012 to May 2013) and compressed into a few seconds.
