When using the LaTeX package url (\usepackage{url} somewhere in the preamble) which tends to give much more nicely formatted web addresses, the following may be preferred:

 @misc{ wiki:xxx,
   author = "Wicri Earth",
   title = "The Blue Marble --- Wicri Earth{,} ",
   year = "2010",
   url = "\url{https://wicri-demo.istex.fr/Wicri/Terre/en/index.php?title=The_Blue_Marble&oldid=1993}",
   note = "[Online; accessed 9-August-2025]"
