Researchers have uncovered more than a thousand previously unknown tectonic ridges across the Moon’s dark plains, showing the ...

Recent research suggests that Saturn's bright rings and its largest moon, Titan, may have both originated in collisions among its moons. While Cassini's 13-year mission expanded our understanding of ...

HONOLULU (KHON2) — Scientists continue to explore the deep story of how Earth and the moon formed. One idea has gained attention because it pushes us to imagine the planet in its earliest and wildest ...

The moon's orbit isn't a perfect circle. Instead, it's more stretched out, kind of like an oval, which means its distance from Earth varies by about 30,000 miles (48,000 km). The surface of the moon ...
