Washington: US space agency NASA said Thursday that its Voyager 1 spacecraft has become the first man-made object to venture into interstellar space.
New and "unexpected" data indicated 36 years after it was launched, Voyager 1 has left the heliosphere, the bubble of hot, energetic charged particles surrounding the solar system, and entered into a region of cold, dark space, known as interstellar space, Xinhua reported citing NASA.
It said the spacecraft arrived in this cold, unexplored interstellar region on or about Aug 25, 2012, and is now about 19 billion km from our Sun.
"Now that we have new, key data, we believe this is mankind's historic leap into interstellar space," Ed Stone, Voyager project scientist based at the California Institute of Technology, said in a statement.
