Rocky Giants: New Findings Reframe Uranus and Neptune Interiors
New Research Challenges the Classic ‘Ice Giants’ Label For decades, Uranus and Neptune have been classified as the Solar System’s “ice giants.” The name implied interiors dominated by water, ammonia, and other ices that solidify under extreme cold. But a bold new approach is turning this idea on its head. In a pre‑print study accepted…

Rocky Giants: Reimagining Uranus and Neptune Interiors
Introduction: Rethinking the Outer-Planet Class For decades, Uranus and Neptune have been branded the solar system’s ice giants. Based on early models, scientists believed these distant worlds were dominated by frozen ices—water, ammonia, and methane—surrounding a rocky core. But fresh research is challenging this long-held label, proposing a more nuanced interior structure that could even…

Are Uranus and Neptune Really Ice Giants? New Research Hints at a Rockier Interior
Rethinking a Long-Standing Label: Ice Giants or Rock Giants? For decades, Uranus and Neptune have been classified in astronomy as “ice giants,” a category that places them between the hydrogen-helium gas giants (Jupiter and Saturn) and the rocky Terrestrial planets. A recent study accepted for publication in Astronomy & Astrophysics invites scientists to reconsider that…
