   Explanation: On April 20, 2023 the shadow of a [5]New Moon raced across
   planet Earth's southern hemisphere. When viewed [6]along a narrow path
   that mostly avoided landfall, the Moon in silhouette created a
   [7]hybrid solar eclipse. Hybrid eclipses are rare and can be seen as a
   total eclipse or an annular "[8]ring of fire" eclipse depending on the
   observer's position. Viewers of this much anticipated hybrid event were
   able to witness a total solar eclipse while anchored in the Indian
   Ocean near the centerline of the eclipse track off the coast of western
   Australia. This ship-borne image from [9]renowned eclipse chaser Fred
   Espenak captured the active Sun's magnificent outer atmosphere, or
   [10]solar corona, streaming into space. The composite of 11 exposures
   ranging from 1/2000 to 1/2 second, taken during the 62 seconds of
   totality, records an extended range of brightness to follow alluring
   details of the corona not quite visible to the eye.
