Astronomy is growing now more than ever. There are more candidates than there are jobs. This is not a bad thing, because the more people want to work in astronomy the more we can accomplish. It's not as easy a career to pursue as it once was, but not impossible.
High education is encouraged, as in almost any science. Most astronomers have a Ph.D. The minimum requirement for training is a Senior Certificate with a matric exemption. It takes about 10 years of school to be an astronomer. You need to go through your first 4 years of college to get a Bachelor of Science Degree, usually in physics, math, engineering, or chemistry.
An assistant professor of astronomy can make $30,000 to $40,000 per every nine months. They are employable at age 33, or 16 years after they graduate from high school.
