In a paper published today in Nature Astronomy, the confirmation of a second exoplanet in a circumbinary system—also known as a two-star system—about 1,300 light-years from Earth is examined. This finding is significant because it is just the second time that astronomers have verified the existence of two planets in a circumbinary system. It also has the potential to advance our understanding of how planetary systems emerge and develop across the universe.Artist illustration celebrating the discovery of planet BEBOP-1c using the radial-velocity method at telescopes in the Chilean Atacama Desert operated by the European Southern Observatory.
