Seeing Where Stars Collide
Hilo HI (SPX) Jun 17, 2015
Scientists have imaged a cluster of stars, heavily obscured by material in our galaxy, where stars are so densely packed that it is likely a rare environment where stars can collide. "It's a bit like a stellar billiards table; where the probability of collisions depends on the size of the table and on the number of billiard balls on it," said Francesco R. Ferraro of the University of Bologna (Italy), one of the team members who used the Gemini Observatory to make the observations. The cluster of s ... read more
