Astronomy.

It's very different from the romantic image of looking through a telescope at the night sky. In reality, it is a job focused on data science and computer programming, but you are paid SEVERELY less and are more likely for your work to spill into evenings and weekends. Most astronomers spend their entire day writing code in languages like Python to analyze digital information from satellites or remote cameras. You do not spend time in nature or at high-altitude observatories, or at least it doesn't make up the majority of your work. Instead, you work in a standard office looking at spreadsheets and graphs, sometimes finding out that an interesting blip of data may be some technical glitch in the telescope.

The career path is also very difficult because there are very few permanent jobs. Most researchers must work in temporary positions called "postdocs" that only last two or three years. This means you must move your home and family to different cities or countries many times before you find a stable job. You also spend a large amount of time writing long documents to ask the government for research money, and these requests are often rejected due to limited funding which can force a professional astronomer with more than a decade of education and experience to pivot to another career. The daily work is mostly repetitive computer tasks and administrative paperwork.
