Finding planets that could support life is like searching for a needle in a haystack, but there's a new clue: small planets with big moons.
Our own Moon is incredibly important for life on Earth, keeping our planet stable and even playing a role in how life first appeared.
New research suggests that this kind of moon-planet relationship is more common around smaller planets, potentially making them better candidates for life.
The search for alien life is focusing on these planets with big moons, hoping to find new worlds similar to our own.
