Voyager 2 is the only spacecraft to have visited all four gas giants: Jupiter, Saturn, Uranus, and Neptune.
-
The probe discovered 10 new moons around Uranus and five around Neptune, expanding our understanding of these distant planets.
Discoveries at Jupiter
Jupiter was the first major stop for Voyager 2. The data collected here was groundbreaking.
-
Voyager 2 discovered active volcanoes on Jupiter's moon Io, the first time such activity was observed outside Earth.
-
The spacecraft provided detailed images of Jupiter's Great Red Spot, a massive storm larger than Earth.
Saturn's Secrets
After Jupiter, Voyager 2 moved on to Saturn, revealing more secrets of our solar system.
-
Voyager 2 discovered new rings around Saturn, adding to the complexity of the planet's ring system.
-
The probe found that Saturn's moon Titan has a thick atmosphere, primarily composed of nitrogen.
Uranus and Neptune
Voyager 2's journey continued to the ice giants, Uranus and Neptune, where it made several important discoveries.
-
Voyager 2 discovered that Uranus has a tilted magnetic field, which was a surprising find for scientists.
-
The spacecraft observed Neptune's Great Dark Spot, a storm similar to Jupiter's Great Red Spot.
Beyond the Solar System
Voyager 2 didn't stop at Neptune. It continued its journey into interstellar space, sending back data from beyond our solar system.
-
In 2018, Voyager 2 entered interstellar space, becoming the second human-made object to do so after Voyager 1.
-
The probe is currently more than 11 billion miles from Earth, and it continues to send data back to NASA.
The Golden Record
One of the most fascinating aspects of Voyager 2 is the Golden Record it carries. This record contains sounds and images meant to represent life on Earth.
-
The Golden Record includes greetings in 55 different languages, music from various cultures, and sounds of nature.
-
The record also contains 115 images depicting life on Earth, including pictures of humans, animals, and landscapes.
Longevity and Legacy
Voyager 2's mission was initially expected to last only a few years, but it has far exceeded those expectations.
- The spacecraft is powered by a radioisotope thermoelectric generator, which has allowed it to operate for over 40 years.
Voyager 2's journey and discoveries have significantly expanded our knowledge of the solar system and beyond. Its mission continues to inspire scientists and space enthusiasts alike.
