If you had a car sitting in a garage for nearly forty years you’d forgive it for not starting with the first turn of the key. Now imagine it’s 21 billion kilometers from home and you just heard that engine purring from interstellar space. For car read Voyager 1, and for engine read a set of four trajectory thrusters, and that’s exactly what NASA boffins have done. The handlers of Voyager –... 

Entering the unknown: This artist’s impression shows how plasma flows around NASA’s Voyager 1 spacecraft as it gets close to entering interstellar space Nasa’s Voyager 1 is on the verge of becoming the first human-made object to enter interstellar space, scientists say. First launched in 1977, the unmanned spacecraft has been in uncharted territory since last year. Scientists had... 

Heliopause is the theoretical boundary where the Sun’s solar wind is stopped by the interstellar medium Voyager 1 has reached a new part of space that connects the magnetic fields of the solar system to intergalactic space. NASA announced that it had found a new layer of space on Monday, located 11 billion miles from Earth. NASA said recordings from the space probe indicate that it has entered... 

More than three decades after launching, NASA’s workhorse spacecraft is inching closer to leaving the solar system behind. Currently 11 billion miles away from the sun, Voyager 1 has been exploring the fringes of the solar system since 2004. On Monday, the spacecraft entered a new region, known as the ‘stagnation zone’ – an area close to the very edge of our solar system, affording...
