The Physics Teacher
This month's cover features Mercury's silhouette against a roiling backdrop of Texas-sized convection cells on the surface of the Sun. The brighter regions indicate an upflow of hotter gas revealing an effect known as solar granulation. The original image is monochromatic (the reddish 705.7 nm TiO spectral line); the ghostly ring around the planet is an artifact of the adaptive-optics system (see Using the 2016 Transit of Mercury to Find the Distance to the Sun).
