The Sun is a giant sphere of hydrogen and helium, undergoing constant nuclear fusion reactions at its core. This fusion releases an immense amount of energy, radiating light and heat that reaches every corner of the solar system. Without the Sun, Earth and the other planets would be frozen worlds, devoid of life.
Earth is the only planet known to support life, thanks to its perfect blend of water, atmosphere, and distance from the Sun. Its diverse ecosystems range from vast oceans to dense rainforests and icy polar regions. Earth’s magnetic field protects it from harmful solar radiation, ensuring the survival of its inhabitants.
Mars, with its rusty red surface, offers evidence of ancient rivers and lakes, suggesting it may have once supported life. Today, scientists are exploring its polar ice caps and studying its soil for signs of water. As technology advances, Mars is the top candidate for future human colonies and exploration missions.
Galaxies are enormous collections of stars, gas, and dust, bound together by gravity. The Milky Way, our home galaxy, is just one of trillions in the universe. The vast distances between galaxies are measured in light-years, emphasizing just how immense the universe is.
Our spiral galaxy, home to our solar system and billions of stars.
The closest galaxy to the Milky Way, on a slow collision course with us.
Black holes are among the most fascinating objects in space. With gravity so strong that even light cannot escape, these cosmic giants challenge our understanding of physics and the universe itself.
The boundary around a black hole where nothing can escape.
Found at the center of galaxies, including our own Milky Way.
