Summary:
- Scientists have discovered that it rains deeply inside the interiors of planets, even giant gas planets like Jupiter and Saturn. This is a surprising finding that challenges our previous understanding of how planets form and evolve.
- The rain inside these planets is made of exotic materials like liquid metallic hydrogen, which can only exist under the extreme pressures and temperatures found deep within the planets. This "deep rain" plays a crucial role in shaping the planets' structures and compositions.
- Understanding this deep rain phenomenon could help us better predict the properties of exoplanets (planets outside our solar system) and provide new insights into how our own solar system formed and developed over time.
