📖 Read the story
Scientists found tiny living things very high in the sky. These are called microbes. They live thirty kilometers above the ground. This place is near space. It is very cold there. The temperature is about minus sixty degrees. There is not much air to breathe. The sun is also very strong and dangerous. Most animals cannot live in this place. Scientists used large balloons to find these microbes. Microbes are so small that you need a special tool to see them. These microbes are very strong. Scientists say this cold place is like the planet Mars. If tiny things can live high in the sky, maybe they can live on other planets too! This discovery helps us understand how germs move around the world. It also tells us about life in space. It is an amazing discovery for science.
