Astronomy is about the sky and the people who have spent their lives studying it: stellar physics and cosmology, the worlds of our own solar system and the missions sent to them, the observatories and instruments that made the observations possible, and the long history of one idea displacing another.
Each of our writers brings a different specialty and a different voice — an astrophysicist on how stars are born and die, a historian of science on the arguments that shaped the field, a planetary scientist on what spacecraft data actually shows, an amateur observer who has spent decades at the eyepiece.
