• Voyager 1 (VOYAGER) was launched on October 5th, 1977, from Kennedy Space Center at Cape Canaveral, Florida, United States.
• It was NASA's first mission into interstellar space. Voyager 1 is still operating today and has traveled billions of miles in its lifetime. This video features images taken by Nasa’s Voyager spacecraft of Jupiter, Saturn, Uranus and Neptune over the course of four decades.

• The planets seem to have remained unchanged despite the immense distances between them and our solar system.

• The Voyager 1 spacecraft has traveled 11 billion miles across space since its launch in 1977 and it's still going strong. If that's not impressive enough, consider this - it had no onboard computer at the time it was launched! It's now traveling at over 36000 mph (58500 km/h).

• Uranus' gravity field
The gravity field of Uranus is the second largest in our solar system after Jupiter's (and the strongest due to its lack of atmosphere). Because of this, Uranus orbits the Sun at a distance of about 15 billion miles (24 billion kilometers) from the center of our star. Compared to Earth, Uranus travels through space much slower than other planets, taking 84 years for each rotation around the Sun.
●Voyager 1 is a robotic spacecraft that was launched in 1977. Its primary mission is still ongoing, but it has been modified several times since launch. Voyager 1 was designed to send back data regarding the outer limits of our Solar System and how far away the Sun is from us. This information could help determine if life exists elsewhere beyond Earth. It is currently traveling farther out from the Sun than any human-made object before reaching interstellar space.
• Pioneer 10 & 11
Launched in 1972, Pioneer 10 became the first man-made object to enter interstellar space in 2003. Pioneer 11 followed shortly after in 1973. These probes were both built and operated by NASA's Jet Propulsion Laboratory in Pasadena, California. They are named for their respective missions: Pioneer 10, which means "first," and Pioneer 11, which means "second." Pioneer 10 was launched into orbit around Saturn. Pioneer 11 was launched into an orbit outside Venus. Both probes have continued to function well past their predicted lifespans, and they remain active today.
• Each picture taken from Voyager 1 contains an image of our own planet Earth, blown-up to over 20 times larger than what we can normally see from space. This makes it easy to spot spots like California, Africa, and Australia.
• In 2013, astronomers reported the discovery of two planets orbiting between the orbits of Neptune and Uranus. These are the first exoplanets ever discovered around a star other than the sun.
• In 2011, astronomers using the Hubble Space Telescope observed water falling onto Pluto, indicating that it could potentially have active geysers erupting into space.
• In 2007, the Cassini spacecraft flew by Saturn's moon Titan and snapped a stunning photo of the methane lakes dotted across the surface of the moon.
• Jupiter's north pole, once covered in ice, may be home to underground oceans containing liquid water. New evidence suggests there could be channels connecting these oceans with the atmosphere, allowing life to survive underwater.
●Jupiter’s moons are probably one of the first things any astronomer would tell you about Jupiter. These are the natural satellites that orbit Jupiter. There are four major moons orbiting Jupiter, and they were probably formed after Jupiter captured several comets. The four largest moons are named Ganymede, Europa, Callisto, and Io.
● Ganymede is Jupiter's biggest moon and has the distinction of being one of the few moons that orbits inside the asteroid belt. This is because it was broken off from the surface of Jupiter about 4 billion years ago. Jupiter’s gravity slowly pulled apart the moon until it became an independent satellite.
●Europa is thought to have been created through collision between two objects. One theory suggests that it may have come from a small planet that collided with Jupiter. The other idea states that it could have come from a huge comet that broke into pieces. Either way, this rock is believed to be covered in water ice, much like its neighboring moon, Enceladus.
●Callisto is the innermost of Jupiter's moons. Like Europa, it comes from a collision between two celestial bodies. Its mother body was likely some type of object that had passed too close to Jupiter when it orbited around the giant planet. The collision created a large amount of debris that eventually came together to form the moon.
Finally, we arrive at Io, the smallest but also the hottest of Jupiter's moons. Io is the only known world that orbits in the extremely corrosive Jovian atmosphere. Io looks a little different than the others as its surface is not solid but rather covered with volcanoes. Some scientists think that Io was once part of a larger body before it got broken up. Io appears to be an active place with many geysers and plumes shooting millions of gallons of hot gases into space.

• Galaxy
Our galaxy contains billions of stars, many of which have planets and moons. Our sun is located in one of at least 100 billion galaxies. And while scientists don’t think that extraterrestrial life exists (yet), others argue that we should look into outer space before we make claims about how isolated life might exist on Earth.
• Milky Way
The Milky Way is the name of our galaxy. We are just one spiral arm of the larger cosmic dust cloud called the Local Supercluster. The Milky Way has a mass of about 200 billion times that of the Sun — three quarters of the known universe! The Milky Way consists of a thin disk-shaped central region containing the Sun and Solar System surrounded by a thick band of diffuse dark matter plus multiple arms filled with hundreds of billions of stars.
