Voyager 2 becomes second spacecraft to reach interstellar space
Voyager 1 first achieved the feat in 2012.
Nasa’s Voyager 2 has become only the second human-made object to reach the space between stars.
Nasa said on Monday that Voyager 2 exited the region of the sun’s influence last month.
For the second time in history, a human-made object has reached the space between the stars. Now slightly more than 11 billion miles (18 bil. km) from Earth, @NASAVoyager 2 has now left the Sun's protective bubble & is flying in interstellar space: https://t.co/zRnhiaJqGS #AGU18 pic.twitter.com/Zzncki4GKB— NASA (@NASA) December 10, 2018
The spacecraft is now beyond the outer boundary of the heliosphere, some 11 billion miles from Earth.
It is trailing Voyager 1, which reached interstellar space in 2012.
LIVE NOW: @NASAVoyager 2 launched before its twin in 1977, but followed a longer path away from Earth. Along the way, Voyager 2 has been providing scientists with unprecedented observations of the space it’s traveling through.

Interstellar space is the vast mostly emptiness between star systems.
According to Nasa, the Voyagers are still technically in our solar system.
After visiting Jupiter, Saturn, Uranus and Neptune, @NASAVoyager 2 has left the Sun's protective bubble and is now flying in the interstellar space between the stars.

Scientists maintain the solar system stretches to the outer edge of the so-called Oort Cloud.
It will take thousands of years for the spacecraft to get that far.
The @NASAVoyager 2 probe no longer feels the solar wind & is flying through the interstellar space between the stars. It carries a working instrument providing 1st-of-its-kind observations of the nature of this gateway.

Despite the great distance, flight controllers are still in contact with Voyager 2.
The Voyagers launched from Cape Canaveral, Florida, in 1977.
