Welcome to Little Science Daily! Today we talk about space. Scientists are looking for something called dark matter. Dark matter is very strange because it is invisible. We cannot see it with our eyes or telescopes. Even so, dark matter is everywhere in the universe. Scientists have a special machine named LZ. This machine is deep under the ground. It looks for very small pieces called particles. Recently, the machine saw a small flash of light. This light might be a piece of dark matter! This is very exciting because nobody saw it before. However, the scientists must be careful. They only saw the light one time. They need to find it again to be sure it is real. If they are right, it will help us understand the world better. Dark matter is still a big mystery. Would you like to be a scientist and find invisible things in space?
