Light from Jupiter takes 38 minutes to reach Earth – so when we look up at Jupiter, we see it as it was 38 minutes ago. Similarly, we see the Bullet Cluster as it was 3.7 billion years ago. See how learners can get excited about space, find out what's out there – and how we learn about it! – and connect with scientists exploring the universe. With hands-on activities, sonifications, tactile materials, astronomer profiles, and more, enable your learners to explore the universe and its history with NASA's Chandra Observatory, Universe of Learning, MicroObservatory, YouthAstroNet, and more!
