📖 Read the story
Scientists found two strange planets far away in space. These planets are very large, like the planet Jupiter. But there is something special about them. They are very light and soft. Scientists call them ‘superpuff’ planets. They are as light as cotton candy. Cotton candy is the sweet pink snack people eat at a fair. To find these planets, scientists used special telescopes. One telescope is in Antarctica. It is very dark there for three months every year. This helps scientists look at the stars for a long time. These two planets move in a circle around their star. They pull on each other with a force called gravity. Gravity is like an invisible hand that pulls things together. By watching the planets move, scientists learned they are very light. It is amazing to find big planets that are so soft and fluffy! Would you like to visit a planet made of cotton candy?
