Researchers find evidence of hot water on Mars -- in a rock on Earth

Zircon, often regarded as a time capsule, can reveal the geological history of Mars, including evidence of hot water and hydrothermal processes from 4.45 billion years ago.
Through advanced techniques like scanning electron microscopy, we found intricate growth zones in zircon, indicating Mars had hydrothermal activity similar to Earth, suggesting life could have existed.
