Sara Seager is an astronomer and planetary scientist, searching for exoplanets and hoping to find another earth—another world in the vastness of the universe that can sustain life. But when her husband dies, Seager suddenly feels lost within all that empty space. A widow with two young boys, Seager struggles to find the threads that connect us, both to the cosmos and each other. The Smallest Lights in the Universe is a touching and honest memoir about grief, loss, and reconnecting with the things we love…and with those around us.
