Chinese scientists have made an exciting discovery about the moon. They found water molecules in the soil samples brought back by the Chang’e-5 mission, which returned to Earth in 2020. The discovery of water molecules in lunar soil helps us learn more about the moon and may lead to more findings in the future. This finding was announced by the Chinese Academy of Sciences and published in the journal Nature Astronomy.

1. Discovery: The scientists discovered a type of mineral in the moon's soil that has water molecules in it. They named this mineral "unknown lunar mineral" or ULM-1.
2. Previous Findings: Before this, India’s Chandrayaan-1 spacecraft and NASA’s instruments had also found evidence of water on the moon, but this was mostly from the surface and not from returned samples.
3. Significance: This discovery is important because it helps us understand more about the moon's composition and the presence of water.
4. Future Research: Scientists hope to find more evidence in future missions. The Chang’e-5 mission marked a significant step in lunar exploration, and with more samples from missions like Chang’e-6, we expect to learn even more about the moon.
