      On April 19-20, 2023, an unusual eclipse swept over the Earth on a   
      narrow path, creating fully shadowed skies in Australia, Timor-Leste,   
      and Indonesia. In these locations, full totality first appeared as an   
      annular eclipse, then as a total eclipse, then returned to an annular   
      appearance. Nearby locations outside the thin path of totality (Asia,   
      East Indies, Australia, the Philippines, and New Zealand) experienced a   
      partial solar eclipse.   
      
      This unusual eclipse is known as a “hybrid eclipse”, and they only   
      occur a few times a century. As explained by EarthSky, this type of   
      eclipse is so special because the full eclipse—the moment when the moon   
      is positioned centrally in front of the sun—looks different depending   
      on your location. This variation is caused primarily by the Earth’s   
      curvature.   
      
      The Moderate Resolution Imaging Spectroradiometer (MODIS) on board   
      NASA’s Aqua satellite acquired a true-color image of full totality of   
      the hybrid eclipse on April 20. The island of Timor-Leste is completely   
      shrouded in black, which is the shadow, or the umbra, created by full   
      totality. The umbra also covers other islands in Indonesia and much of   
      the island of New Guinea. A bronze tone surrounds the umbra. This is   
      the penumbra, and people looking up in these regions would experience a   
      partial eclipse.   
      
      The image is a mosaic, acquired in two passes of the satellite. A black   
      section, which cuts through the center of the image, separates the two   
      swaths. Only the swath on the west shows any signs of the short-lived   
      but dramatic hybrid eclipse.
