NASA news: Hubble telescope spots a beautiful galaxy from 200 million light-years away
What is a galaxy?
A galaxy is a huge collection of gas, dust, and of stars and their solar systems.
These bodies are held together by gravity. Our galaxy, the Milky Way, also has a supermassive black hole at its core.
When you look up at stars in the night sky, you are seeing other stars in the Milky Way.
There are so many galaxies other than ours, experts cannot even count them all.
The Hubble Space Telescope looked at a small patch of space for 12 days and found 10,000 galaxies, of all sizes, shapes and colours.
Some astronomers believe there could be as many as one hundred billion galaxies in the universe.
