- 1Spacecraft hunting for life on icy moons swings past Earth●Why a spacecraft exploring moons where life may thrive is zipping by Earth
A spacecraft built to explore icy moons where life could exist is flying close by Earth, using the planet's gravity to adjust its course. The maneuver is part of a long journey toward the outer solar system, where scientists hope to study oceans beneath the moons' surfaces. The flyby has drawn attention as a milestone in the search for conditions suitable for life beyond our planet.
- 2Icy moons may keep hidden oceans even after collisions▼Icy moons may hold on to their underground oceans even after being smashed apart
New research suggests icy moons in the outer solar system could retain their subsurface oceans even if they are shattered by large impacts, with fragments potentially holding on to liquid water. The finding has implications for the search for life, as it widens the range of places where habitable conditions might survive dramatic collisions and reassembling events over billions of years.
