SUMMARY: Astronomers using the giant Gemini South 8-metre telescope in Chile have spotted what seems to be a collision between two planet-sized objects orbiting the nearby star Beta Pictoris. A collision like this would create a lot of dust, but the star is like a powerful fan that should quickly blow it all away. Based on the amount of dust still there, astronomers think the collision happened only 100 years ago, or so. This is exactly like the scenario astronomers believe our own Solar System went through 5 billion years ago as the various planets formed through multiple collisions.
