WASP-43b-Phase-Curve

Data from the Mid-Infrared Instrument on NASA’s Webb telescope shows the changing brightness of the WASP-43 star and planet system. The system appears brightest when the hot dayside of the planet is facing the telescope, and grows dimmer as the planet’s nightside rotates into view. Credit: Taylor J.
