What if you could send a robot on a 12-year journey to photograph a planet no human has ever seen up close?

The Day Voyager 2 Flew Past Neptune!

A brave little spacecraft visits the coldest, windiest planet in our solar system

Voyager 2 became the first (and only!) spacecraft to visit Neptune after traveling for 12 years!

On August 20, 1989, something absolutely incredible happened 2.7 BILLION miles away from Earth. A spacecraft no bigger than a small car zoomed past Neptune, the most distant planet in our solar system!

Voyager 2 had been traveling through space for TWELVE YEARS to get there. That's like if you started a road trip when you were born and didn't arrive until middle school!

When Voyager 2 finally reached Neptune, it discovered some wild stuff. Neptune has winds that blow at 1,200 miles per hour — that's faster than any hurricane on Earth! It found a giant storm called the Great Dark Spot, which was as big as our entire planet. Whoa!

But the coolest discovery? Voyager 2 spotted geysers on Neptune's moon Triton, shooting icy material five miles into the sky. Scientists were shocked because Triton is one of the coldest places in our solar system — yet something was still erupting there!

💡 Voyager 2 is still sending messages back to Earth from over 12 billion miles away — it takes 17 hours for a signal to reach us!
