ANDROMEDA
A Handbook for the Astronomically Curious
Andromeda is an adventurer's field guide to the universe — a place to walk the Moon through its phases, follow a star from cold cloud to glowing remnant, and wander every world in our system. No telescope, no prior stargazing, no permission needed: begin anywhere, learn by navigating, and keep whatever stays with you.
