The Great Barrier Reef stands as one of Earth's most remarkable natural wonders, stretching over 2,300 kilometers (1,400 miles) along Australia's northeastern coast. This massive living ecosystem is so vast that it can be clearly observed from space, making it one of the few biological structures visible to astronauts orbiting our planet.

A Living Colossus

What makes this visibility particularly impressive is that the Great Barrier Reef isn't a solid landmass but rather a complex system comprised of approximately 3,000 individual coral reefs and 900 islands. The collective size of this ecosystem covers an area of about 344,400 square kilometers (133,000 square miles), roughly the size of Japan or Italy. Shutdown123
