    "body_text": "Serendipitous JWST infrared images contain a point source at the position of Type Ic supernova SN 1983V more than 40 years after the explosion. The source differs from nearby ionized regions, and archival Hubble data show a plausible hydrogen-alpha counterpart consistent with continuing shock interaction heating the dust. Modeling favors a torus and about 0.0077 solar masses of dust, which could reflect binary-linked mass loss. Spectroscopy is still needed to confirm that the source is the supernova remnant rather than an interloper.",
