Ariel, Uranus’ Brightest Moon, May Have Once Hidden an Ocean Over 100 Miles Deep

New research published in Icarus suggests that Ariel, one of Uranus’ major moons, may once have harbored a vast subsurface ocean over 100 miles (170 kilometers) deep.

This icy world, known for its fractured terrain and contrasting young and ancient geological features, is increasingly emerging as a potential “ocean world.” By modeling tidal stresses and orbital eccentricity, scientists have reconstructed how Ariel’s dramatic surface features may have formed — and what they reveal about its hidden past.

Colorado’s Wolves Expand Westward as New Map Tracks Their Movements

A new map from Colorado Parks and Wildlife shows wolves wandering farther west toward the Utah border during September, although most of their activity remains centered in the state’s mountainous regions.

The data, collected between August 26 and September 23, reflects shifting patterns in wolf behavior as Colorado continues its voter-mandated reintroduction program.

NISAR’s First Radar Images Capture Maine’s Coast and North Dakota’s Farmlands in Striking Detail

NASA has released the first radar images from its newly launched Earth-mapping satellite, NISAR.

The pictures showcase the rugged Maine coastline and farmlands of North Dakota, revealing features in extraordinary detail. A $1.3 billion joint mission with the Indian Space Research Organization (ISRO), NISAR is designed to survey nearly all of Earth’s land and ice repeatedly, offering transformative insights for climate science, disaster forecasting, and environmental monitoring.
