The Ice Giant Atmospheres of Uranus and Neptune Compared
Quick fact
Despite being similar in size and composition, Uranus shows almost no atmospheric features, while Neptune hosts some of the fastest winds in the solar system, reaching over 2,000 km/h—likely powered by Neptune's internal heat, which Uranus lacks.
Why this is interesting
You've seen Neptune's deep blue storms and Uranus's tranquil, pale glow—but why are these two ice giants, so similar in size and composition, so strikingly different? What hidden forces create such contrasting faces?
