Traditionally, the emergence of life is linked to the presence of a star, which provides the necessary energy for chemical processes. However, a new study from 2025 challenges this notion.
The research indicates that moons, which are ejected into deep space by planets during supernova events, might retain subsurface oceans. These oceans could remain heated not by sunlight, but through the gravitational flexing caused by their orbits.
This finding opens up new possibilities for understanding where life might exist beyond our solar system, suggesting that life could potentially thrive in environments previously thought to be inhospitable.
