When a star spins super fast, its magnetic field becomes enormously powerful. Imagine a ball of plasma moving at full speed. The rapid rotation causes...
The gravity of a planet is basically its ability to hold onto everything that passes nearby. When the planet is too small, its gravitational force...
Ancient civilizations observed the phases of the Moon directly without any special instruments. They simply had to look up and follow its cycle of about...
Ancient civilizations often worshipped the Sun because of its crucial role in agriculture. Without the Sun, there would be no photosynthesis, thus no plants, and...

The pyramids, these imposing structures, also served as genuine astronomical observatories for the ancient Egyptians. They used their architectural precision to track the movements of...
X-rays are invisible forms of light. They have a very high energy. Their wavelength is short, which means they easily pass through a lot of...
Stars begin their life as giant clouds of gas and dust. Under the effect of gravity, these clouds contract to form protostars. When the temperature...
In winter, the marked contrast between the very cold air near the ground and the warmer layers of air higher up enhances atmospheric turbulence. The...
Tromsø is a city located in northern Norway, beyond the Arctic Circle. It is situated at about 69 degrees north latitude. This means it is...
