GEOLOGIC ACTIVITY SCAN 🧊

Randomized: 5 Questions from our Advanced Research Bank.

THE LIQUID OCEAN

Mathematical models suggest a 200km thick saltwater ocean exists beneath the ice. How a small body keeps enough internal heat to prevent freezing for 4.5 billion years is a major heat-budget mystery.

OCEAN EVIDENCE
Status: Hypothesized

AMMONIA PEAKS

Short-lived ammonia has been detected near Virgil Fossae. Since UV radiation destroys ammonia quickly, its presence implies very recent (or ongoing) cryovolcanic eruptions from the interior.

ATMOSPHERIC VANISHING

Newer 2018–2024 occultation data shows Pluto's atmosphere is currently "collapsing" or refreezing as it retreats from the Sun, yet some areas show unexpected thermal inertia that keeps the gas stable.
