Polar Weather Clues on Jupiter and Saturn Reveal Interiors
Polar Patterns at the Poles For years, astronomers have watched Jupiter and Saturn from afar, marveling at their colossal storms and swirling bands. Yet at the poles, their weather behaves like a different planet. Recent analyses suggest that the north and south poles of these gas giants host distinct atmospheric conditions. These polar weather patterns,…

Mysterious Polar Weather on Jupiter and Saturn Unveiled
Decoding polar weather patterns on gas giants For decades, scientists have been puzzled by the starkly different weather patterns observed at the poles of Jupiter and Saturn. Despite their similar sizes, compositions, and distances from the Sun, the two giant planets exhibit weather systems that behave in markedly distinct ways. A new line of research…

Earth’s Core Unveiled: Seismic Clues Point to an Onion-like Inner Iron Layer
New Evidence Suggests an Onion-like Core Structure For decades, scientists have probed Earth’s interior with seismic waves that travel through the planet during earthquakes. A new wave of research synthesizes these signals to paint a surprising picture of the Earth’s core: the inner iron center may be layered in a way that resembles an onion…

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…
