Astronomy flashcards

Astronomy stacks a lot of distinct vocabulary on top of physics you have to apply. You need the stages of stellar evolution in order, the differences between a red giant, white dwarf, neutron star, and black hole, and the meaning of terms like luminosity, redshift, and parallax — alongside laws like Kepler's and the inverse-square relationship for brightness. Read it once and most of it fades. Active recall — reconstructing a sequence or definition from memory — is what makes it durable, and the testing effect means each retrieval reinforces the last. Spread reviews across days, and the spacing effect returns each fact just before it would slip away.

Cram turns your own astronomy material into a deck, so you study your course and not a stranger's set. Paste your notes, drop in a chapter PDF, share a link to an article, or type a topic like "the Hertzsprung-Russell diagram" — and Cram's AI writes clean question-and-answer cards in seconds. Spaced repetition then schedules every card to return right when you're about to forget it, with an exam countdown to pace your revision. No ads, no lockouts, and decks work offline, so a stargazing night with no signal is still study time.
