Today’s Image of the Day from NASA Earth Observatory features the Great Blue Hole, which is located off the coast of Belize in the Caribbean Sea near the center of the Lighthouse Reef atoll.
The mysterious hole and its surrounding coral reefs are among the top diving destinations in the world.
The deeper, dark blue waters of the massive marine sinkhole stand out against the clear blue shallow waters of the reefs.
According to NASA, the Great Blue Hole likely formed during the last Ice Age when global sea levels were much lower.
The Lighthouse Reef and the Great Blue Hole make up just a small portion of the Belize Barrier Reef system, one most pristine marine ecosystems with some of the greatest biodiversity on the planet.
The photograph was captured by an astronaut onboard the International Space Station on March 5, 2020.
