A new moon was found near Neptune, joining the other 13 we knew about. It's so small that it wasn't detected during the Voyager 2 flyby in 1989.

Thirty years ago, NASA's Voyager 2 mission flew by Neptune, capturing the first close-up images of the blue gas giant. Before this, the eighth planet in our solar system was only known as a fuzzy ...

A passing star, or a stellar flyby, with the potential to pull Neptune out of its orbit by just 0.1%, could mean catastrophe for the entire solar system. But don’t worry — it won’t happen in ...

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 ...

WASHINGTON (AP) — Neptune's glowing auroras are captured in the best detail yet by NASA's James Webb Space Telescope. Hints of auroras were first faintly detected in ultraviolet light during a ...

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 ...

To date, there has been only one mission to Neptune, the Voyager 2 flyby of 1989. That flyby capped a "grand tour" of the outer planets that took advantage of a unique gravitational alignment to ...

One problem with a return mission to Neptune is that a flyby focused solely on that world does not provide significant bang for the buck. Without the lucky alignment available to missions in the ...

For decades, images taken of Neptune have looked like the planet has a deep blue hue, while Uranus seemed more green. However, these two ice giants may actually look more similar to eachother than ...

Astronomers have observed a mysterious large dark spot in Neptune’s atmosphere, along with a bright feature that has never been spotted before. CNN values your feedback 1.
