The national median is $128,820 a year. The bottom tenth earn $78,010 or less and the top tenth $195,190 or more, in 2025 figures. Those figures count people already employed as astronomers, which mostly means university faculty, national observatory staff and federal researchers. They do not count doctorate holders who moved into another field.
$37,000 a year
The National Science Foundation's graduate fellowship stipend, for 3 of 5 years
It also pays $16,000 a year toward tuition. Students without the fellowship are usually paid through teaching or research assistantships with tuition waived. You should not be paying tuition for a science doctorate.
$132,620 a year
The median in Maryland, home to a NASA (National Aeronautics and Space Administration) center and the Space Telescope Science Institute
Only 5 states publish a figure. Arizona ($129,020) is next and Hawaii is the lowest, at $102,000. Nine-month university salaries get topped up with summer research money from grants. Part of an academic astronomer's pay can be money they had to win by writing proposals.
Roughly, all in
$30,000 to $70,000
Tuition, fees, exams and kit. Not rent, food or travel
The expensive part of this career is the bachelor's degree, not the doctorate. The low end is community college credits transferred into an in-state public physics or astronomy program, plus graduate application fees. The high end is four years of in-state public tuition at the top of the range. Doctoral programs in astronomy almost always waive tuition and pay a stipend instead, funded by the department, a research grant or a national fellowship, so the five or six years after the bachelor's cost time rather than money.

Universities
Teaching plus research. The classic job, and the one everyone is competing for.
National observatories and research centers
Staff scientist roles that come with telescope or instrument responsibilities.
Federal agencies
Space and defense agencies hire astronomers as civil servants through USAJOBS (the federal government's hiring site).
Industry
Finance, technology and defense companies hire astronomy doctorates for data and modeling work.
The exact path from high school to qualified.
There is no shortcut. Research astronomy runs on the doctorate.
High school
Grades 11 and 12
Physics and the highest math your school offers, plus any coding you can pick up. An astronomy club is fun but the physics is what matters.
Bachelor's degree
4 years
Physics or astronomy. Get into a research group by your second year, because a summer research placement is what makes a graduate application competitive.
Doctorate
5 to 7 years
Coursework, then years on one research problem, then a thesis. Funded by teaching and research assistantships or a fellowship.
Postdoctoral research
2 to 6 years
Short fixed-term research jobs, usually two or three years each, often in another city or country. Most people do one or two.
Permanent position
If it happens
A faculty job, an observatory staff role or a federal research post. This is the narrow gate, and plenty of good people do not get through it.
Physics
Astronomy is physics applied to things that are far away.
Calculus
Take the most advanced math available. Every serious astronomy program assumes it.
Computer science
Modern astronomy is mostly writing code to handle enormous data sets.
English
Careers here are decided by written research proposals and papers.
Nobody licenses astronomers and no exam stands between you and the title. The filter is the job market. It is a very small occupation: O*NET OnLine (the Department of Labor's occupation database) counted about 2,400 astronomers in 2025 and projects about 100 openings a year to 2035. Growth is rated much faster than average, but on a base that small it adds few jobs. That is not a reason to skip it, but it is a reason to build skills on the way through, especially coding and statistics, so a doctorate in astronomy leaves you employable in a dozen other fields.
Large public research universities
Most states have one with an astronomy or astrophysics department, and in-state tuition makes the undergraduate degree affordable.
University of California Berkeley
One of the long-established American astronomy departments, running both undergraduate and doctoral programs.
Summer research programs
The National Science Foundation funds paid undergraduate summer research placements at universities and observatories. Apply in your first or second year.
Things you don't need, but that help.
Serious programming
Python, version control and working with data sets measured in terabytes. This is the single most transferable thing you learn.
Statistics and machine learning
Modern surveys produce more data than anyone can look at. The methods are the same ones industry pays for.
Instrument building
Designing detectors, optics and electronics. Hardware people are rarer than data people and get hired by both labs and companies.
Public outreach
Planetariums, science museums and science communication are real careers for people who love the subject but not the grant treadmill.
A summer research placement
Do at least one during your bachelor's degree. It is close to required for doctoral admission.
A published paper
Even a small one as a junior author changes how a graduate committee reads your file.
A second area, like geology or atmospheric science
Planetary science sits between fields and hires people who can cross over.
Comfort with odd hours
Observing runs are overnight, and telescope time is scheduled when the sky says so.
The National Aeronautics and Space Administration hires its civil servants through USAJOBS (the federal government's hiring site). Its Pathways internship program is described by the agency as a direct pipeline to full time employment, and students can apply while still in school. Astronomers also work at contractors and university institutes attached to those agencies.
Day to day, pros and cons, where you'd work.
Far less stargazing than you would think. Most days are spent at a computer writing code, cleaning data that came off a telescope months ago, and running models. Add a group meeting, a seminar, teaching or supervising students, and long stretches of writing: papers, and proposals asking for telescope time or grant money. Observing runs happen a handful of nights a year, and even those are often done remotely or by a technician who sends you the files.
The good
The hard parts
Things people don't tell you.
For the James Webb Space Telescope's fifth year, astronomers asked for 99,782 hours of observing in 2,568 proposals. About 8,000 hours were available, so roughly 1 hour in 12 was granted.
Professional telescopes feed detectors, not eyes. You submit a proposal, a scheduler decides whether you get the nights, and what arrives is a pile of data files. Some astronomers go an entire career without visiting the telescope that made their career.
Light takes time to travel, so every image of a distant galaxy shows it as it was when the light left, sometimes billions of years ago. Astronomers are the only scientists who can watch the past directly.
Every list is built from the same numbers shown above, so you can see where this career sits next to the others.
