Daily Weather Cycle On Exoplanets (IMAGE) University of Toronto Caption An artist's rendering of an exoplanet with cloudy mornings and clear, scorching afternoons, exhibiting a cycle of phase variations that occur as different portions of the planet are illuminated by its star, as seen from Earth. Astronomers at the University of Toronto, York University and Queen's University Belfast used measurements of the phase variations of six exoplanets obtained by the Kepler space telescope to forecast their daily weather cycle.
