Interstellar Comet Incoming: 3I

Is there an alien visitor in our solar system right now? 👽☄️

Not exactly—but there is something just as rare. A comet from another star system, named 3I, is currently passing through our solar system. It’s believed to be the third interstellar object scientists have ever detected. Astrophysicist Erika Hamden explains why discoveries like this are so exciting, and what they tell us about the vastness of our galaxy. As our tools improve, we may be on the verge of spotting even more of these cosmic travelers. 🔭✨
