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 dot ...

In this combination image released by ESA/Webb, left, an enhanced-color image of Neptune from the NASA/ESA Hubble Space Telescope and right, that image is combined with data from the NASA/ESA/CSA ...

Neptune’s supersonic winds and icy storms revealed a planet so extreme that it forever changed our picture of the solar ...

It was 24 January 1986 when Voyager 2 flew by Uranus on its never-ending outbound journey from the solar system. Three and a half years later, on 25 August 1989, the probe flew past Neptune and became ...

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. When you purchase through ...

Global color mosaic of Triton, taken in 1989 by Voyager 2 during its flyby of the Neptune system. Neptune’s moon of Triton, now under study as a target for a NASA flyby mission dubbed Trident, may be ...

Voyager 2's image of Neptune released shortly after the flyby in 1989 (left) with the newly reprocessed version in true colour (right). A new study suggests that Neptune and Uranus are a similar shade ...

New models suggest Uranus and Neptune may hold far more rock than expected, raising questions about how these distant planets formed.

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 our ...

Imagine predicting an entire planet's existence with nothing but math, and then finding it right where the numbers ...

Researchers at the University of Toronto created a model to observe how close a flyby star would have to be to pull a planet from our solar system out of its orbit. Future Publishing via Getty Imag A ...
