One of four concepts being considered for a Discovery Program mission, Trident would investigate one of the solar system’s most unusual worlds. When NASA’s Voyager…
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…
In 1989, NASA’s Voyager 2 zipped past Neptune—its final planetary target before speeding to the outer limits of the solar system. It was the first…
Astronomers using the NASA/ESA Hubble Space Telescope, along with older data from the Voyager 2 probe, have revealed more about the origin of Neptune’s smallest…
Since Pluto’s demotion from fully-fledged planet to dwarf planet, Neptune holds the title of outermost planet in the Solar System. This new image of the…
ESO’s Very Large Telescope (VLT) has achieved first light with a new adaptive optics mode called laser tomography — and has captured remarkably sharp test…
Three billion miles away on the farthest known major planet in our solar system, an ominous, dark storm – once big enough to stretch across…
NASA has released the first study of potential future missions to the mysterious “ice giant” planets Uranus and Neptune. The Ice Giant Mission Study is…
Seventy days worth of solar system observations from NASA’s Kepler spacecraft, taken during its reinvented “K2” mission, are highlighted in this sped-up movie. The planet…
This newly released image of Neptune and its large moon Triton was captured by NASA’s New Horizons Spacecraft as it continues on its voyager towards…
This historic image of Neptune was taken twenty-five years ago by NASA’s Voyager 2 Spacecraft. NASA’s Voyager 2 spacecraft gave humanity its first glimpse of…
The Lunar and Planetary Institute used Voyager’s 1989 historic footage of Neptune’s moon Triton to construct the best-ever global color map of the strange moon….
Using new techniques to suppress Neptune’s glare, astronomers view Neptune’s innermost moon for the first time since it was discovered by Voyager 1989. Neptune’s tiny,…
While analyzing Neptune photos taken by the Hubble Space Telescope, an astronomer discovered a new moon orbiting Neptune. Designated S/2004 N 1, the new moon…
In a newly published study, researchers detail the atmospheric circulation patterns of Uranus and Neptune, finding that the streams of gas observed in the atmosphere…
