   Explanation: Five bright comets are compared in these panels, recorded
   by a coronograph on board the long-lived, sun-staring [5]SOHO
   spacecraft. Arranged chronologically all are recognizable by their
   [6]tails [7]streaming [8]away from the Sun at the center of each field
   of view, where a direct view of the overwhelmingly bright Sun is
   blocked by the coronagraph's occulting disk. Each comet was memorable
   for earthbound skygazers, starting at top left with [9]Comet McNaught,
   the 21st century's brightest comet (so far). [10]C/2023 A3
   Tsuchinshan-Atlas, approaching its perihelion with the active Sun at
   bottom center, has most recently grabbed the attention of comet
   watchers around the globe. By the end of October 2024, the blank 6th
   panel may be filled with bright sungrazer comet [11]C/2024 S1 Atlas.
   ... [12]or not.
