Hints of auroras were first faintly detected in ultraviolet light during a flyby of the Voyager 2 spacecraft in 1989. Webb captured Neptune's shimmering lights in infrared light, providing direct ...

Faint hints of Neptune’s auroras were first detected during Voyager 2’s flyby of the planet, but Webb’s latest discovery is the first direct evidence of the phenomenon. “Turns out ...

If a star gets too close to Neptune during a “stellar flyby” and knocks off its axis by 0.1%, it could destabilize the entire solar system as a result, according to research published by ...

offer the clearest look at the planet’s narrow rings and faint dust bands since NASA’s Voyager 2 became the first spacecraft to observe Neptune during its flyby in 1989. “In addition to ...

NASA's Voyager 2 was the first spacecraft to see Neptune in all its gaseous glory, during a 1989 flyby. No other spacecraft have visited the icy, blue planet. So it's been three decades since ...

Voyager 2, a NASA probe launched in the 1970s, also glimpsed two dark storms on Neptune during its 1989 flyby of the planet, but those disappeared well before Hubble could observe them when it ...

Voyager 2 conducted a flyby of Uranus in 1986, and the images revealed a planet with a more pale cyan or blue color. The vessel flew by Neptune in 1989 and the imagery showed a planet with a rich ...

Researchers have shared a radical new idea for how to put a spacecraft in orbit around Neptune: Use the thin atmosphere of Triton, Neptune's largest moon, to capture it. The only spacecraft to ...

The James Webb Space Telescope's first images of Neptune, the mysterious ice giant that orbits in the far reaches of the outer solar system, were so spectacular that even astronomers could barely ...
