There are certain bays around the world that glow in the dark due to the presence of bioluminescent organisms.
These organisms, such as plankton and algae, emit light when they are disturbed, creating a magical and breathtaking effect. The most famous bioluminescent bays can be found in Puerto Rico, the Bahamas, and Australia.
3. The Shortest War in History
The shortest war in recorded history was between Britain and Zanzibar on August 27, 1896, and lasted only 38 minutes.
Zanzibar surrendered after just 12 minutes of fighting, and the remaining 26 minutes were spent on ceasefire negotiations. The war was sparked by a dispute over who should be the ruler of Zanzibar.
4. The Largest Living Organism
The largest living organism in the world is a fungus called Armillaria ostoyae, also known as the honey mushroom. It covers over 2,200 acres in Oregon, USA, and is estimated to be around 2,400 years old.
This massive fungus grows by sending out underground tendrils that break down organic matter and absorb nutrients.
5. The Deepest Part of the Ocean
The deepest part of the ocean is called the Challenger Deep, located in the Mariana Trench in the Pacific Ocean. It has a depth of approximately 36,000 feet or about 6.8 miles.

The snowflake was so large that it looked like a small piece of white silk floating in the air.
8. The Hottest Planet in the Solar System
The hottest planet in our solar system is Venus, with surface temperatures reaching as high as 462°C (863°F).
This is due to a runaway greenhouse effect caused by the thick atmosphere of carbon dioxide that surrounds the planet. The high temperatures on Venus make it one of the most inhospitable places in the solar system.

The cave is known for its unique geological features and diverse wildlife, including rare species of bats and salamanders.
20. The Oldest Known Living Thing
The oldest known living thing is a fungus called Armillaria ostoyae, which is estimated to be around 8,650 years old.

This fungus grows by sending out underground tendrils that break down organic matter and absorb nutrients. It is considered a single living organism because it is all connected by a vast network of fungal hyphae.
21. The Largest Waterfall by Volume
The largest waterfall in the world by volume is the Inga Falls, located on the Congo River in the Democratic Republic of Congo. The waterfall is over 9 miles (15 kilometers) long and has an average flow of 48,000 cubic meters (1.7 million cubic feet) per second.
