This synthetic image is a slice of a much larger simulation depicting the cosmos as NASA's Nancy Grace Roman Space Telescope will see it when it launches by May 2027. Every blob and speck of light represents a distant galaxy (except for the urchin-like spiky dots, which represent foreground stars in our Milky Way galaxy). (Image by C. Hirata and K.
