Off the Solomon Islands, researchers discovered the world’s largest coral colony—measuring 112 by 105 feet, larger than a blue whale. Initially mistaken for a shipwreck, this massive structure is so large it can be seen from space. Estimated at hundreds of years old, it has survived climate events that killed countless other reefs, offering hope that some coral ecosystems are more resilient than scientists thought.

From the desk: Finding a thriving giant that’s been quietly growing for centuries reminds us that nature still holds surprises.
