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

When Voyager 2 flew by Neptune in 1989, it sent back images that were processed to better reveal features like bands and a dark spot. But a new study says it's actually a greener planet.

More than 30 years have passed since the Voyager 2 fly-bys of Uranus and Neptune. I discuss a range of lessons learned from Voyager, broadly grouped into process, planning, and people. In terms of ...

A new computational model suggests that Uranus' and Neptune's cores may be less icy than their "ice giant" nickname suggests.

Nearly four decades after Voyager 2 skimmed past Uranus, a fresh look at its measurements is reshaping what scientists ...
