Galaxies are like giant cities made of stars, gas, and dust held together by gravity. The Milky Way is shaped like a spiral, with arms spinning around a central bulge. Some galaxies are large and bright, while japan mobile number others are small and faint. Scientists use powerful telescopes to study distant galaxies and learn more about how they formed and evolved.
Black holes and supernovae
Outer space is full of mysteries, such as black holes and supernovas. A black hole is a place where gravity is so strong that nothing, not even light, can escape it. It's like a cosmic vacuum cleaner that sucks in everything nearby.
Supernovae are huge explosions that occur when stars run out of fuel and collapse. They shine brightly for a short time, then fade away. Supernovae can create new elements and scatter them into space, helping to form planets and even life.
Telescopes: Eyes on the Universe
How do we see all these outer space wonders? With a telescope! Telescopes are like giant eyes that help us see distant objects in the sky. Some telescopes are located on Earth, like the Hubble Space Telescope, which orbits high above our planet and takes amazing pictures of distant stars and galaxies.
