The Mystery of Jupiter's Missing Water
Despite being the largest planet, Jupiter is surprisingly dry. While scientists expect to find vast amounts of water deep in its atmosphere, actual measurements reveal far less than chemical models predict.
Jupiter is primarily composed of hydrogen and helium, matching the raw materials that formed our sun. However, the unexpected shortage of oxygen and water puzzles researchers who study planetary evolution. This suggests that the early formation of our solar system was more complex than we once imagined. We are still learning why this gas giant failed to gather as much water as its neighbors.
