In 1977, NASA launched Voyager 1 to explore the outer planets and far beyond. Since then, Voyager 1 has traveled over 14 billion miles, capturing extraordinary images of our solar system. This slideshow highlights 13 of the most breathtaking images Voyager 1 sent back to Earth, along with some from its sister spacecraft, Voyager 2, on their incredible journeys toward interstellar space.
Earth and the Moon – A Distant View
Taken on September 18, 1977, Voyager 1 became the first spacecraft to capture both Earth and its Moon in a single frame. At a distance of 7.25 million miles from Earth, this iconic image shows the Moon floating beyond our home planet, emphasizing the vastness of space.1

Jupiter’s Great Red Spot
In early 1979, Voyager 1 provided a close-up of Jupiter’s Great Red Spot, a storm larger than Earth. This swirling mass of clouds, first observed centuries ago, gave scientists new insight into Jupiter’s turbulent atmosphere, thanks to the detailed images captured by Voyager.
Active Volcanism on Io
During its flyby of Jupiter’s moon Io, Voyager 1 discovered something unprecedented—active volcanoes. This was the first observation of volcanic activity on another celestial body besides Earth. Voyager detected plumes erupting miles into space, revealing Io’s fiery surface.
Saturn’s Breathtaking Rings
Voyager 1 reached Saturn in 1980, capturing stunning images of its intricate ring system. Saturn’s rings, composed of countless ice and rock particles, revealed a beauty never before seen. Voyager even discovered a new, faint G-ring and enigmatic spokes in the B-ring.2
Titan’s Hazy Atmosphere
As Voyager 1 flew past Saturn’s largest moon, Titan, it detected a thick atmosphere primarily composed of nitrogen. Titan’s opaque haze left its surface hidden, fueling speculation about the moon’s geological secrets. This image offered a glimpse into one of the most mysterious moons in our solar system.
The Pale Blue Dot
Perhaps the most famous image Voyager 1 ever captured is the “Pale Blue Dot,” taken on February 14, 1990, from 3.7 billion miles away. In this image, Earth appears as a tiny speck, less than a pixel in size, suspended in a sunbeam. Carl Sagan’s reflections on this image remind us of our small place in the vast universe.

Close-up of Europa
Voyager 1 also flew by Jupiter’s moon Europa, capturing images of its icy surface. The close-up showed evidence of potential subsurface oceans, raising the possibility of life beneath its frozen crust. These images set the stage for future missions to study Europa more closely.
Voyager 1’s Family Portrait of the Solar System
In 1990, Voyager 1 captured a family portrait of the solar system from beyond Pluto. This composite image includes six planets: Jupiter, Saturn, Uranus, Neptune, Earth, and Venus. It’s a striking reminder of our solar system’s expanse and the spacecraft’s journey far from home.
Saturn’s Moons – Tethys, Dione, and Rhea
Voyager 1 captured images of Saturn’s moons Tethys, Dione, and Rhea in 1980, showcasing their cratered surfaces and icy landscapes. These moons, though small, are integral parts of Saturn’s complex system of rings and satellites.
The F Ring of Saturn
One of the discoveries made by Voyager 1 was the narrow, braided F ring of Saturn. This stunning image shows the intricacies of the ring’s structure, including its twists and clumps, revealing a dynamic system shaped by gravitational interactions with Saturn’s moons.
Entering Interstellar Space
In 2012, Voyager 1 became the first human-made object to enter interstellar space, crossing the heliopause—the boundary between the solar wind and interstellar medium. The spacecraft’s data showed a steep drop in solar particles and a rise in cosmic rays, confirming this historic milestone.
A Golden Message to the Cosmos
Voyager 1 carries the Golden Record, a 12-inch disc containing sounds and images from Earth. This record, curated by Carl Sagan and his team, serves as a message to any intelligent life that might find it, showcasing humanity’s diversity and curiosity.
Beyond the Solar System
Voyager 1’s journey continues today, traveling at 38,000 miles per hour into interstellar space. Though its power is diminishing, the data it sends back from beyond the solar system gives us unprecedented insight into the universe beyond the Sun’s influence.
Conclusion
Voyager 1’s images, from the close-up of Jupiter’s Great Red Spot to the distant Pale Blue Dot, have changed our understanding of the cosmos. As it continues its journey through interstellar space, this remarkable spacecraft reminds us of humanity’s quest for discovery beyond the stars.
