We construct the exact solution of one (anti)instanton in N=1/2 superYang-Mills theory defined on non(anti)commutative superspace. We first identifyN = 1/2 superconformal invariance as maximal spacetime symmetry. For gaugegroup U(2), SU(2) part of the solution is given by the standard(anti)instanton, but U(1) field strength also turns out nonzero. The solutionis SO(4) rotationally symmetric. For gauge group U(N), in contrast to the U(2)case, we show that the entire U(N) part of the solution is deformed bynon(anti)commutativity and fermion zero-modes. The solution is no longerrotationally symmetric; it is polarized into an axially symmetric configurationbecause of the underlying non(anti)commutativity. We compute the `informationmetric' of one (anti) instanton. We find that moduli space geometry is deformedfrom hyperbolic space (Euclidean anti-de Sitter space) in a way anticipatedfrom reduced spacetime symmetry. Remarkably, the volume measure of the modulispace turns out to be independent of the non(anti)commutativity. Implicationsto D-branes in Ramond- Ramond flux background and Maldacena's gauge-gravitycorrespondence are discussed.Comment: 39 pages, 3 figures, JHEP style; v2. typos corrected + a paragraph  adde
