The NASA spacecraft Voyager 1 has become the first man-made object to leave the solar system and enter the cold, obscure space between the stars, reports Euronews.
NASA scientist, Gary Stark, explained where Voyager had got to.
“We’ve exited the material created by the sun and we’re truly in an alien environment. The material in which Voyager finds itself is not created by the sun. It’s created in fact by our neighbouring stars supernova remains and so forth,”- he said.
At its launch in September 1977, Voyager 1 carried messages from world dignitaries such as then US President Jimmy Carter, as well as recorded sounds and music to communicate with any life form it might come across.
36 years and nearly 19 billion kilometres later, Voyager is still sending faint signals back to base.
The plutonium batteries are due to die by 2020 but it’s thought Voyager 1 may continue rattling through space for billions of years.
