What is a galaxy?
It is a huge collection of gas, dust, and billions of stars and their solar systems. They are all held together by gravity. There are 3 main types of galaxies, classified based on their shape: spiral, elliptical, and irregular.
Features of a galaxy:
1. Each has millions, billions or trillions of starts depending on its size.
2. Almost all galaxies – except a few tiny dwarf galaxies – have a supermassive black hole at the centre.
3. All galaxies tend to spin and have significant magnetic fields.
