Melkeveien

Her et sted bor du. Diameteren på melkeveien er et sted mellom 100 000 og 120 000 lysår. En gang i fremtiden må vi evakuere fra vår lille planet fordi solen vil vokse etterhvert som den slipper opp for drivstoff. Husk å fly med et selskap hvor de har avkjølet chardonnay.

(CNN) -- Hurtling across the Milky Way like an eternal explorer -- the Voyager 1 spacecraft continues to nonchalantly reveal the mysteries of the solar system to a captivated Earthbound audience.

Active volcanoes, methane rain, icy geysers and intricate details about Saturn's rings -- the list of revelations attributed to the mission reads like fantastical sci-fi novel but it has revolutionized planetary astronomy.

Thirty-seven years after it launched, Voyager 1 is still out in the vast expanse of space, periodically relaying new data back home. But in 2013, NASA made the groundbreaking announcement that Voyager 1 had left the heliosphere -- a magnetic boundary "bubble," if you will, which scientists use to explain the separation of our solar system from the rest of the galaxy.

"That means Voyager has traveled outside the bubble of our sun," explains Voyager project manager Suzy Dodd. "The data Voyager 1 sends us now is data from other stars and from super nova eruptions and the remnant of stars that have exploded over the course of history."

It's an incredible achievement for a probe built for an initial five-year mission. But now, not for the first time since the extraordinary statement, doubts have been cast on whether the craft has actually made the historic crossing.
