Celmins's intense monochromatic images of the night sky, based on photographs, focus on small and individual marks in the context of vastness. The images seem fragile because they record a specific human glimpse through a telescope or camera which is ephemeral and frozen in time. Celmins's serial exploration of her subjects, including the night sky, allows the artist to exploit the distinct characteristics of the variety of media she uses. Celmins has explained that her galaxy drawings stem from a love of exploring "the blackness of the pencil". The charcoal ground has a dark opacity but contains endless variations. Celmins uses an eraser to bring out the stars in the night sky.
