• Flying Over Saturn's Moon Mimas • This movie was made of narrow angle images taken over a period of 7 hours during Cassini's close encounter with Saturn's moon Mimas on August 2, 2005. During the movie, the moon appears to rotate through about 115 degrees and the range varies from 253,000 to 64,000 km (158,000 to 40,000 miles). The image scale in the final pan across the surface, is about 760 meters per pixel. •• Credit: NASA/JPL/Space Science Institute | Astronomy Nation

🌌 Mimas — the tiny Saturn moon with a big secret This is Mimas, a small, cratered moon that looks like a frozen rock. In 2024, a team re-analyzed Cassini tracking data and found strong evidence that Mimas hides a global ocean beneath its icy shell — about 20–30 kilometers under the surface — and that the ocean is young, likely less than 25 million years old. 🧪 How did they figure this out? Instead of looking for geysers or fractures, researchers modeled subtle changes in Mimas’s orbit and rota

Mimas es un satélite natural de Saturno, conocido por su cráter gigante Herschel, que le da una apariencia distintiva. Descubierto en 1781, Mimas tiene una superficie helada y craterizada, y su órbita lo lleva a experimentar fuerzas de marea que pueden generar calor interno y posible actividad geológica en su interior. #astronomia #cosmos #Ciencia #universo #telescopio | Boveda Celestial
