Nasa's Voyager 2 probe reaches interstellar space

Spacecraft becomes second human-made object to reach space between stars

Nasa's Voyager 2 has become only the second human-made object to reach the space between stars.

Nasa said that the spacecraft left the region of the sun's influence last month and is now beyond the outer boundary of the heliosphere, about 11 billion miles from Earth. It is trailing Voyager 1, which reached interstellar space - the vast, mostly empty area between star systems - in 2012.
