Astounding is formed from "astound" (from Old French *estoundre*, meaning to stun or astonish) and the suffix "-ing" (indicating the action or process). The word "astounding" means the action of causing great surprise or wonder.
Think of something that 'stuns' you ('astound') and the '-ing' shows it's happening right now — that's why astounding means something that is currently causing great surprise.
