Star Hits the Hard Surface of a Supermassive Sphere (image) University of Texas at Austin Share Print E-Mail Caption This is the first in a sequence of two artist's impressions that shows a huge, massive sphere in the center of a galaxy, rather than a supermassive black hole. Here a star moves towards and then smashes into the hard surface of the sphere, flinging out debris. The impact heats up the site of the collision. Credit Mark A.
