Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. It's true that bright moonlight scattered by the atmosphere tends to mask faint stars, but pictures of the sunlit portion of the Moon made with earthbound telescopes or even with cameras on the lunar surface often fail to show any background stars at all . Because the exposure times are too short. Very short exposures, lasting fractions of a second, are required to accurately record an image of the bright lunar surface. The final representation of Moon and background stars is very dramatic, even though it could not have been captured in a single exposure.
