Reaching interstellar space isn't just something that happens in science fiction movies.
NASA has confirmed that its Voyager 2 probe has just entered interstellar space, becoming the second man-made object in history to do so.
Voyager 1 was the first in 2012, but its successor has the tech to make unprecedented observations.
Scientists say Voyager 2 exited the heliosphere, our Sun's protective bubble, on November 5th.
Now, the probe is more than 11 billion miles from Earth in interstellar space.
The probe was launched back in 1977 and has gone way beyond its original mission, but it's just getting started studying a region we don't know much about.
