Scientists from Cambridge found signs of life on a planet called K2-18b. They used a telescope to study the planet's air. They found gases that on Earth are made by small living things. But they need more information to be sure.

The planet K2-18b is very far away. It is 124 light years from Earth. The scientists think the planet might have an ocean. This ocean could have life. But they are not sure yet. They need to study more to know for sure.

Other scientists have different ideas about the planet. Some think it might not have life. They say the gases could come from other things. The scientists will keep studying to find the truth. They hope to know more in one or two years.
