Summary:

• **What Scientists Discovered About Life on Other Planets**: Scientists have found that water and oxygen alone are not enough for life to exist on other planets. They discovered that two additional important ingredients are needed, which helps us understand what conditions other planets must have to support living things like we have on Earth.

• **Why This Discovery Matters**: By learning what makes a planet able to support life, scientists can better search for living organisms on other worlds. This research helps us know which planets and moons in our solar system and beyond might be good places to look for life, making space exploration more focused and successful.
