Astronomers using NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) have observed an unusually warm, dusty debris disk around BD +20 307, a binary star system located 300 light-years away in the constellation of Aries. Their results suggest that an extreme collision between two rocky planetary bodies is the most likely origin for the warm dust in the BD +20 307 system.
