"During a routine time-lapse observation of the solar chromosphere [the thin, reddish layer of the Sun’s atmosphere above the visible surface], I captured a serendipitous moment when an aircraft crossed the field of view. Preserving this transient frame, I employed multiple blending modes to enhance the details of the solar background. Beyond stacking individual video frames, I processed the sequence, undertook colour inversion and synthesised 100 images through combined mean and minimum blending. This dual approach effectively accentuated both bright plages [active regions in the chromosphere] and dark laments through enhanced contrast. "The composite image reveals the evolution of the Sun’s dynamic surface across a two-hour observational period, while the aircraft’s two-second transit remains frozen in time. This layered imaging rearranges time, blending celestial bodies and human technology in one photo."

    If you need a blast of beauty (and who doesn't?) I highly recommend browsing the new Astronomy Photographer of the Year winners. They're spectacular -- and neither of these shots even made it to #1.
