Astrophage is a microorganism that consumes solar energy—essentially a “sun‑eating” microbe. In Project Hail Mary it’s draining the Sun (and other stars), threatening Earth and other star systems, and is the central problem Ryland Grace’s mission must solve by finding why Tau Ceti is resistant and sending back a biological countermeasure.
