New scientific findings suggest Voyager I is very close to leaving the solar system.
The study set for publication in the journal Geophysical Research Letters initially suggested that Voyager I became the first man-made object to reach interstellar space on Aug. 25, 2012.

Drastic changes in radiation levels were recorded at that time, and galactic cosmic rays (cosmic radiation from outside the solar system) spiked to levels not seen since Voyager's launch in 1977, the American Geophysical Union said today.

But NASA officials were skeptical, and later released a statement to TIME via email saying Voyager had not left the solar system.
The spacecraft has reached a new area of space called the "magnetic highway," but is waiting for a dramatic change in the direction of the magnetic field before placing Voyager in interstellar space, officials at NASA's Jet Propulsion Laborary told Fox News.
Thirty-five years after its launch, Voyager I is by far the furthest man-made object from the sun at an estimated 11 billion miles away.
