Happy #HobbitDay to those who celebrate! We don't typically cover the exploits of Bilbo, Frodo, or other hobbits in our pages, but we have loads about #NewZealand, where the "Lord of the Rings" movies were filmed in their entirety. Check it ➡️ eos.org/tag/new-zeal...
The cover of the October 2024 issue of Eos magazine, which features a photograph of a New Zealand fjord bounded by steep mountainsides and below a blue sky with wispy white clouds. The cover line reads "Land of the Long White Cloud and the Deep Blue Sea: Innovative geoscience projects are documenting Aotearoa New Zealand's deep history--and far-reaching future--on land and sea."

Here's more evidence that caves and karst are extremely cool: This bioluminescence in a limestone karst cave in Australia's Dorrigo National Park. These gnat larvae produce luminous adhesive liquid droplets, which attract and trap insects to provide a food source for the gnats.
