The average human body has about 30 trillion cells. But the number of bacteria living in the human body is on average 39 trillion, which is more than the number of cells in the body. In the picture, a type of bacteria can be seen, which plays a key role in the digestive system.

The image below, taken by Venera 9 in 1975, is the first clear image of the surface of Venus. Venus is the hottest planet among the solar system's planets. This probe recorded a temperature of about 485 °C on the surface of Venus. Meaning that these stones are like a hot oven.

A rogue planet is a planet that doesn't revolve around any star and moves alone in a galaxy. It's said that the number of rogue planets in the Milky Way may be 100,000 times the number of its stars. But due to coldness and weak radiation, these planets are difficult to discover.

Angel falls in Bolivar state of Venezuela with a height of 979 meters is the highest waterfall in the world. In a part of the waterfall, the water of the river falls as much as 807 meters. This height is so high that the water becomes a spray before reaching the ground.

The below artwork of moon craters was created by Hamid Naderi Yeganeh using the mathematical equations written in the image.

The fastest human-made object is Parker Solar Probe which can travel at a speed of 690,000 km/h, roughly equivalent to 1/1600 the speed of light. Parker was launched in 2018 and in 2025 it will approach the surface of the Sun at a distance of about 10 times the radius of the Sun.

The image below shows two galaxies colliding. This pair of colliding galaxies is called Arp 273, which is located 300 million light-years away. The outer arm of the larger galaxy is distorted. The reason is that the smaller galaxy had an unsuccessful hit with the larger galaxy!

Amber is a stone formed by the fossilization of tree resin. Sometimes, living organisms are placed inside the resin, and when the resin turns into stone, fossils of several million years are created from it. The insect fossil in the picture is 40 to 50 million years old.

Tenochtitlan was the center of the Aztec Empire (a native nation in the Americas). When Europeans arrived in this city in 1519, it was one of the world's largest cities with at least 200,000 inhabitants, and only Paris, Venice and Constantinople had such a population in Europe.

Emperor penguins can hold their breath underwater for up to 27 minutes and go to a depth of 500 meters. At a depth of 500 meters, the water pressure is so high that without strong bones, the pressure difference between the water and the air inside causes damage to the body.

WOH G64, the red supergiant which can be seen in the center of the image below, is one of the largest known stars with a radius of approximately 1540 times the radius of the Sun. This dying star has a mass less than 30 times that of the Sun, despite this large radius.

In 1960, Norwegian archaeologist Anne Stine Ingstad and her husband discovered the remains of a Norse presence in Canada 1,000 years ago. With this discovery, it became clear that Christopher Columbus wasn't the first European who arrived North America other than Greenland.

While a laptop can do a few billion operations in a second, the brain can do approximately one billion billion (1000000000000000000) operations per second. But it's used for things such as image recognition in the brain. That's why the laptop is faster in math calculations.
