Thirty years ago, we saw the planet Neptune up close for the first time. Swipe to see some of what our Voyager 2 mission revealed about the eighth planet in 1989.

Neptune, a gas giant planet, is a world of storms, with winds that can be three times faster than Jupiter's and nine times faster than Earth's.

Neptune hosts a set of gossamer-thin rings, captured here partially backlit by the Sun, a view impossible to see from Earth.

Neptune’s moon Triton circles the planet in a direction opposite to Neptune’s rotation, which suggests it's an object that the giant planet captured. Despite the extreme cold, Voyager 2 discovered geysers on Triton spewing icy material upward more than 5 miles (8 kilometers). Just hours after its closest approach, Voyager 2 left the Neptune system behind forever, and began its long journey into interstellar space. We’ve never been back — yet.

You can begin your own Neptune exploration at solarsystem.nasa.gov/neptune.

One step closer to Europa! Europa Clipper, our upcoming mission to Jupiter’s intriguing ocean moon, is ready to move into the next phase. Coming up is the final design, followed by construction and testing of the spacecraft and science payload.

The mission will conduct an in-depth exploration of Jupiter's moon, Europa, and investigate whether the moon, which hides an ocean of liquid water beneath its icy shell, could harbor conditions suitable for life.

What lies beneath: on the Moon, impact craters offer geologists a peek at materials found beneath the lunar surface. This spectacular view of Jackson Crater on the Moon’s far side comes from our Lunar Reconnaissance Orbiter.

Jackson Crater is about 45 miles (72 kilometers) across. The central peak rises a little more than a mile (about 1800 meters) above the crater floor. Get more details at lroc.sese.asu.edu/images

This new Hubble Space Telescope view of Jupiter, taken on June 27, 2019, reveals the giant planet's trademark Great Red Spot, and a more intense color palette in the clouds swirling in Jupiter's turbulent atmosphere than seen in previous years. The colors, and their changes, provide important clues to ongoing processes in Jupiter's atmosphere.

The bands are created by differences in the thickness and height of the ammonia ice clouds. The colorful bands, which flow in opposite directions at various latitudes, result from different atmospheric pressures. Lighter bands rise higher and have thicker clouds than the darker bands.

The @OSIRIS_REx spacecraft has been mapping asteroid Bennu in detail, looking for a spot to collect a sample. And today, we can announce the final four sites, selected for their safety, science value, ease of navigating to the site, and the size of rocks and dust that the spacecraft can collect. Check out @OSIRIS_REx for more info.

August 5th is a red-letter day in space exploration. In 2011, our Juno spacecraft set sail for Jupiter on a mission to study the giant planet’s mysterious interior. In 2012, the Curiosity rover touched down on Mars. Both missions succeeded — and both continue their quests today. Follow along at solarsystem.nasa.gov
