? ? ? The Moon transits the Sun, as seen from the vantage point of our Solar Dyamics Observatory satellite on Nov. 7, 2018. There's scientific value in capturing images of these transits: The sharp edge of the lunar limb helps researchers measure how light diffracts around the telescope's optics and filter support grids, allowing scientists to better calibrate their instruments.
