资源简介：
When an uncharted comet enters the solar system emitting rhythmic radio pulses, astrophysicist Callen Yeo joins an expedition to investigate. But inside the icy core, they discover an impossible structure, a city, abandoned and preserved in vacuum, built by something that knew humanity before humanity existed. As the comet alters course toward Earth, Callen must decode its purpose before it delivers either salvation or an ancient reckoning.
