What it pays

Government survey numbers — not estimates, not ads.

Half of all Astronomers in the U.S. earn more than $128,820 a year — the middle 80% land between $78,010 and $195,190. About 2,120 people in the U.S. do this work. Figures are for the U.S. occupation group “Astronomers”. (U.S. Bureau of Labor Statistics survey, published 2025.) In India, Professionals earn about ₹38,298 a month on average — around ₹4.6 lakh a year (government PLFS survey via ILOSTAT, occupation-family figure).

Same family of work — each with its own tasks and prompts.

The LLOS Work Atlas is the world's largest evidenced task library — a map of human work, with a ready prompt behind every task. 1,774 careers · every task named by the sources that witnessed it — O*NET, ESCO, real job descriptions, Wikipedia — and the deepest tasks by several at once. And it is honest about limits: where AI cannot help, the map says so.
