A partially obscured fusion furnace

Once a plasma enthusiast, always a plasma enthusiast... Jean Jacquinot, former director of JET and of the French CEA Research Department for Controlled Fusion (and now an advisor to ITER Director-General Bernard Bigot) began his career in fusion in the mid-1960s. When he retired some forty years later he found himself a new passion: astrophotography. On Friday 20 March he took this striking image of our own familiar fusion furnace as it was partially obscured by the moon. (Note the small solar flare on the lower right of the Sun edge.)
