Ask Slashdot: How To Pick Up Astronomy and Physics As an Adult?
First time accepted submitter samalex01 (1290786) writes "I'm 38, married, two young kids, and I have a nice job in the IT industry, but since I was a kid I've had this deep love and passion for astronomy and astrophysics. This love and passion though never evolved into any formal education or anything beyond just a distant fascination as I got out of high school, into college, and started going through life on more of an IT career path. So my question, now that I'm 38 is there any hope that I could start learning more about astronomy or physics to make it more than just a hobby? I don't expect to be a Carl Sagan or Neil deGrasse Tyson, but I'd love to have enough knowledge in these subjects to research and experiment to the point where I could possibly start contributing back to the field. MIT Open Courseware has some online courses for free that cover these topics, but given I can only spend maybe 10 hours a week on this would it be a pointless venture? Not to mention my mind isn't as sharp now as it was 20 years ago when I graduated high school. Thanks for any advice or suggestions."
I went to an Ivy League school, and we actually had a professional astronomer visit and beg us not to try to get a job in the field! There are NO jobs in the field, at least paying jobs.
I can't give you any specific advice, but maybe a local astronomy club?
I know one of the people who discovered Hale-Bopp is a gifted amateur, and I'm quite certain lots of stuff by amateurs happens which is pretty cool.
In fact, I get the impression lots of amateurs can give coverage which the "pros" can't really do just because of the sheer number of amateurs.
Good luck with it. Hopefully people can point you at more concrete stuff, but you'd hardly be the first amateur who contributed something to the field if you get there.

I've been a physics professor at a large public university for 22 years, and have taught many introductory classes. (Yes, we are innovating our teaching with new techniques -- different question.)
You will never learn anything by reading books or watching videos. The only way to learn physics is by working problems. Hard problems, that make you sweat, and lots of them. But you can do this, and with the online resources you could be successful. Also you can pace yourself.
Ten hours per week is one class. Start with calculus based mechanics, (kinematics, Newton's laws, work-energy theorem, conservation of momentum, energy, and angular momentum.) If you can do the problems in a standard university physics book, then move on to electricity and magnetism. If you get through that and you don't think Maxwell's equations are the most awesome thing ever, then stop.
Also, never be afraid to learn your math in a physics course. It's the best way.
Good luck! You could really enjoy this if you will truly work at it for 10 hours per week as you suggest. But like dieting, you have to commit.

Don't do it, man! You'll have a hard time finding a good (read interesting) job without a PhD and with a PhD, you'll be out of work at 50. And you'll be bitter. Oh, and that PhD needs to be from a top ten university and you need to work for a big name and you'll have to work a lot harder than you think unless you're real smart. Oh, you'll also have to do a post-doc at an even better university and with an even more famous professor. If you're real smart and lucky you can make six-figures. Maybe, till you turn 50. Then you have to find something else to do. Or maybe you can get an academic job and you'll have to work 80 hours/week for 5 to 7 years after that post-doc till you get tenure, if you do. If you don't then you start over. And you may never make six-figures. It's a lot harder to be a happy chemist these days.
What is that up there . . .

Start reading it. They go through the basics and have articles on how amateurs can contribute to research.
But you really need to limit your expectations. Observational astronomy (even amateur-style) requires several hours of daytime prep work, followed by 1-2 hours of equipment setup and familiarization, before you even embark in a 3-4 hour observation run. After an observing run, you might have another 2-10 hours of data processing to do.
If you have a wife, two kids, and a day job, you will get pretty tired pretty quick.
Good equipment (solid mount, high quality telescope, imaging system, star stracker) is not cheap either and, sadly, most people need to invest in or borrow good equipment before they can really evaluate if they like it or if they want to stick with it.
I was an astronomer until I left the field last year after I graduated with my PhD. First, I definitely think it's great you want to contribute to research. My personal suggestion is to find a local astronomy club and see what they're doing. Find some books, news articles, etc... to read. That will hopefully give you a decent introduction. If you live near a university with a decent astrophysics program, you can also see if they have any public lectures or, if you want something more intense, attend seminars (though they're typically during the day). They're typically open to the public, but you should probably e-mail first just to double check. There are also things like Galaxy Zoo and similar projects that let you get involved without any commitment.
If you want to get more serious, you should think about what you want to do. Do you want to do any research? Participate in volunteer activities? Just go observing? For the latter, local astronomy clubs (or star parties) would be a good first start. Some of the big observatories also have programs for amateur observing. Mauna Kea is absolutely amazing for this - every night at the visitor center they bring out some decent sized telescopes (decent sized for seeing with your eyes) and there's usually a bunch of volunteers to help understand what they're pointing them at. Oftentimes dedicated amateurs will come up as well with even bigger telescopes and are happy to share. You also sometimes get professional astronomers who hang out there (like I did a few nights) though the amateurs are usually better at describing what you're seeing (professional astronomy is all about physics - not pretty images).
If you live near a big observatory (mostly southwest US, California, or Hawaii) you can also try to volunteer to be a docent there or something similar. Many of the observatories have some program for volunteers to help lead tours, attend public talks by researchers, and similar. The more dedicated volunteers get some perks, like joining for observing runs, seeing some of the behind-the-scenes things at the telescopes, and similar.
On the research side, it's a lot harder and a lot more investment (time, money, or both). To be able to do semi-independent research in astronomy you'd need to basically do a PhD. That's 40-50 hours a week (at least) for 5-7 years. It's hard. You can do more limited things though. For example, the AAVSO (American Association of Variable Star Observers) is a great organization that organizes observing of variable stars and provides some support to write up the results. Amateur data has been used in many papers. But, this requires having your own telescope that can take scientific quality images. You can also work on data analysis, but this will definitely require some time to understand how to do it. I'd also point out that most people underestimate how hard it is to write a scientific paper. Especially your first one.
As for going into it professionally, I agree with others who have said there are few jobs in the field. Especially if you have a family, it would be very hard to start from scratch.
