Due to its large size and icy surface (due to the presence of water, methane, and ammonia), Uranus is known as the “ Ice Giant. ” It is one of the two ice giant planets along with Neptune. Uranus and Neptune are two planets in the solar system that experience  diamond rain . Researchers have confirmed this theory in the lab. ( Source ) Uranus is one of the two planets (along with Venus) that spin on their axis from east to west . All the other planets rotate from west to east. ( Source ) The clouds in the upper atmosphere of Uranus are mainly composed of hydrogen sulfide. It is the reason that the planet  smells like rotten eggs . ( Source ) Neptune is farther from the sun than Uranus, but Uranus has the  coldest atmosphere among all the planets in the solar system. The temperature at the troposphere of Uranus is between -153 to -218 C .  ( Source ) At least  27 moons  are orbiting Uranus. Compared to moons of other planets named after ancien...

African bush elephant, Asian elephant, and African forest elephant are the three largest animals on land. African bush and forest elephants were considered the same species till 2010. They were later confirmed as separate species after a genetic study in 2010.  Elephant's trunk is very useful and strong. These mammals use them to eat, drink, breath, and smell. They can lift a blade of grass to objects weighing more than 700 pounds through these long noses. Elephants have the highest number of facial neurons among land animals , and nearly half of them control trunk. ( Source ) There are around 40,000 muscles and 150,000 muscle fascicles in the elephant’s trunk, but it is without bones. The trunk is the most sensitive part of the elephant’s body. It can die in case of any damage to this body part. ( Source ) Elephants can  inhale water through their trunks  at a speed of 540 km/h. It is 30 times faster than the speed of our sneeze.

There are around 15,000 species of ants. The Australian state of Queensland hosts nearly 1,400 ant species, the highest number of native species. ( Source ) A recent study shows that  ants' nests  can indicate the presence of gold in the soil. Ants bring gold from underground into their mounds, providing a clue of gold underneath the ground. ( Source ) Colobopsis explodens (exploding ant) is an ant species in Southeast  Asia  that explodes itself to protect its nest. In this  suicidal procedure , the worker ant explodes and secrets a yellow-colored toxic to kill the invader. ( Source ) The fastest ant in the world is the Saharan Silver ant (Cataglyphis bombycina). This ant in Sahara can travel at a speed of 108 times its body length per second. Their long legs assist them in achieving a pace of one meter per second when finding food during the daytime in the desert . ( Source ) In the African savanna, ants  protect trees  from...

Iceland, an island country in Northern Europe, has the lowest population density in Europe and is also one of the most sparsely populated countries in the world. In the 1960s, an  island appeared  in the North Atlantic Ocean (20 miles from the southern coast of Iceland) after an eruption. This island (named Surtsey) is still almost untouched by humans, as only a few researchers can enter here. ( Source ) Deildartunguhver  Thermal Spring in Iceland is the  most powerful hot spring  in Europe , while the hot spring pipeline from this place to Akranes is the longest in Iceland. The towns of Akranes and Borgarnes get most of their water for central heating through this hot spring. A geyser (also named Geysir) in Haukadalur (Iceland) is the  oldest known geyser  in the world. The English word geyser is taken from this Geysir. ( Source ) Iceland has the highest  usage of marijuana  in the world. More than 18% of people in t...

Colombia is a transcontinental country with its major part in South America. A few of its small islands are in North America. Colombia is the only country in South America  with a  coastline on both the Pacific Ocean and the Caribbean Sea.
