What would it mean to unlock the mysteries of both the visible and invisible dark night skies? In Matthew Bothwell’s article Monsters in the Dark, the Cambridge astronomer eloquently and patiently explains the invisible monster galaxies uncovered by the Hubble Space Craft’s long-exposure images. Relying on infrared light exposures, the new imagery penetrates the cosmic dust barriers to reveal in his words: a “vibrant cosmic powerhouses in the distant Universe” engaged in active star-making.
Bothwell admits that we don’t know why these massive galaxies even exist. The spiritual-cosmological questions that follow could sound like these: “What forces bring them into existence?” “Why do they die?” and most profoundly, “Why, or what purpose do they serve?” This busy star-nursery also fosters questions about our own existence back here on Earth and to what degree are we alone in the universe.
