N2 - A light pseudoscalar coupled to two photons would be copiously emitted by the core of a supernova. Part of this flux would be converted to γ rays by the galactic magnetic field. Measurements on the SN 1987A γ-ray flux by the Gamma-Ray Spectrometer on the Solar Maximum Mission satellite already imply a bound on the coupling g<3×10-12 GeV-1. The improved generation of satellite-borne detectors, like EGRET or the project GLAST, could be able to detect a pseudoscalar-to-photon signal from a nearby supernova, for allowed values of g. © 1996 The American Physical Society.
