Dustiest Star Could Harbor a Young Earth
Artist's conception of a possible collision around BD +20 307 that might have created some of the dust observed in the recent Gemini/ Keck observations. The collisions responsible for this dust could range in size from the largest known asteroids (approximated here) to planets the size of the Earth or Mars.Credit:
