This e-book is part of a series called Hubble Focus, which presents some of Hubble's recent cosmic discoveries. Its cover, shown here, features an illustration of the scorching hot planet Kepler-13Ab that orbits extremely close to its host star, Kepler-13A, which is part of a multiple star system. The star’s companions, Kepler-13B and the small orange-red dwarf Kepler-13C, are in the background.
