Correct the misused or missing articles and rewrite the paragraph.

Stars are large balls of spinning hot gas like our sun. The stars look tiny because they are far away. Many of them are much larger than sun. Did you know that a Milky Way galaxy has between two hundred billion and four hundred billion stars in it? Scientists estimate that there may be as many as five hundred billion galaxies in an entire universe! Just like a human being, the star has a life cycle from birth to death, but its lifespan is billions of years long. The star is born in a cloud of cosmic gas and dust called a nebula. Our sun was born in the nebula nearly five billion years ago. Photographs of the star-forming nebulas are astonishing.
