Voyager spacecraft finds solar system is bigger than thought

An artist's concept of NASA's Voyager spacecraft, which is now about 11 billion miles from the sun, NASA said.

Story highlights

  • Voyager 1 is about 11 billion miles from the sun and was launched in 1977
  • Voyager 1 finds new region of solar system, rather than the edge as scientists had predicted
  • Voyager 2 is about 9 billion miles from the sun on a different flight path
Are we there yet? If you're Voyager 1 and you're looking for a spot beyond the end of our solar system, the answer is no.
NASA officials have been saying for months that Voyager 1 is almost there when it comes to interstellar space as it continues the longest road trip in the history of mankind.
Voyager 1 and Voyager 2 took off 16 days apart in 1977, and Voyager 1 is now about 11 billion miles (18 billion kilometers) from the sun.
On Monday, project officials said new information sent back from the ship yielded a surprising result.
