Using a D0-brane as a probe, we study the spacetime geometry in theneighborhood of N D-branes in matrix theory. We find that due to fermionic zeromodes, the coordinates of the probe in the transverse directions arenoncommutative, and the angular part is a fuzzy sphere.Comment: 10 pages, minor modificatio
