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 Jupiter’s Great Red Spot, Neptune’s Great ...

The solar system ice giants Neptune and Uranus have finally revealed their true colors — thanks to images collected by Voyager 2 three decades ago that have been polished with data from the Hubble ...

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. The new ...

It's been one Neptunian year—or about 165 Earth years—since astronomers first observed the most distant planet from the sun.

Neptune's tumultuous atmosphere gives rise to vortices similar to Jupiter's Great Red Spot, but storms on Neptune usually just last a few years. For the first time, astronomers are watching one of ...

While the Hubble Space Telescope might be most famous for its images of beautiful and far-off objects like nebulae or distant galaxies, it also takes images of objects closer to home, including the ...

A new treatment of images collected by Voyager 2 in the late 1980s using data from the Hubble Space Telescope has revealed the actual colors of the solar system's distant ice giants, Neptune and ...
