More than 30 years have passed since the Voyager 2 fly-bys of Uranus and Neptune.

Even by the wild standards of the outer solar system, the strange orbits that carry Neptune's two innermost moons are unprecedented, according to newly published research.

30 Years Ago Voyager 2 Flew Past Neptune

Thirty years ago, on Aug. 25, 1989, NASA's Voyager 2 spacecraft made a close flyby of Neptune, giving humanity its first close-up of our solar system's eighth planet.

Images taken by the Hubble Space Telescope document the formation of a Great Dark Spot on Neptune for the first time, report researchers in a new study.

Like Earth, Uranus and Neptune have seasons, which likely drive some of the features in their atmospheres. But their seasons are much longer than on Earth, spanning decades rather than months.

Three billion miles away on the farthest known major planet in our solar system, an ominous, dark storm -- once big enough to stretch across the Atlantic Ocean from Boston to Portugal -- is shrinking out of existence as seen in pictures of Neptune taken by NASA's Hubble Space Telescope.

SLAC's X-ray laser and Matter in Extreme Conditions instrument allow researchers to examine the exotic precipitation in real-time as it materializes in the laboratory

Scientists have helped solve the mystery of what lies beneath the surface of Neptune - the most distant planet in our solar system.

Huge Storm Observed On Neptune

Storm's surprise appearance in area where no such cloud has been seen before

New images obtained on May 16, 2016, by NASA's Hubble Space Telescope confirm the presence of a dark vortex in the atmosphere of Neptune.

The interiors of several of our solar system's planets and moons are icy, and ice has been found on distant extrasolar planets, as well.

NASA's Kepler spacecraft, known for its planet-hunting prowess of other stars, is also studying solar system objects. In its new K2 mission, Neptune and two of its moons, Triton and Nereid, have been imaged.

Neptune's tiny innermost moon, Naiad, has now been seen for the first time since it was discovered by Voyager's cameras in 1989.

Similar to the giant gas planets Jupiter and Saturn, their smaller cousins, Uranus and Neptune, have long been known to harbor swirling clouds and violent winds churning up their atmospheres. Massive bands of jet streams encircling the entire planet have been observed in both cases.

What is the long-range weather forecast for the giant planets Uranus and Neptune? These planets are home to extreme winds blowing at speeds of over 1000 km/hour, hurricane-like storms as large around as Earth, immense weather systems that last for years and fast-flowing jet streams.
