NASA's Voyager 2 spacecraft is now flying through the stars

Voyager 2, at 11 billion miles from Earth, has entered the stars. 
Monday morning NASA announced that the legendary exploration spacecraft had left a protective bubble produced by the sun's wind and energy, called the heliosphere, and is now hurtling through interstellar space. 
Voyager 2 is the second spacecraft to ever reach the outer limits of the solar system and enter into the interstellar wilderness. Voyager 2's counterpart, Voyager 1, previously entered the stars in 2012.
