What is a conjunction?
Astrology, explained straight
A conjunction is when two planets occupy the same degree — or very close to it — in the sky at the same time. Their energies don't just sit next to each other; they fuse into a single, louder signal.
Astrologers read it as the strongest aspect because there's no separation between the two planets' domains — they operate as one combined force. A Mercury-Saturn conjunction doesn't give you Mercury thoughts and Saturn discipline separately; it gives you one voice that is simultaneously fast and slow, curious and cautious, until you learn to work that tension. The tighter the degree, the more intense the merger.
Conjunctions in your chart are your loudest placements — the themes you can't escape, for better or worse. If the planets involved naturally get along (say, Venus and Jupiter), the conjunction amplifies ease. If they clash by nature (say, Mars and Saturn), the fusion is a constant negotiation you didn't ask for but absolutely have to master.
Find the conjunctions in your chart and treat them as volume knobs turned all the way up — those are the themes that define you, so you'd better understand them.
