![]() ![]() ![]() The fate of being consumed by a star is believed to be the ultimate destiny for many planets, including Earth in about 5 billion years. The discovery of an exoplanet whose orbit is decaying as it orbits an aging star provides a new understanding of the gradual process of planetary orbital decay by offering the first glimpse of a solar system in its final stages. The doomed planet, first discovered by the Kepler space telescope, is on a collision course with its expanding star, ultimately leading to its destruction. The impending demise of Kepler-1658b as it orbits its aging star offers an opportunity for scientists to gain insight into the fate of other planets and their evolving solar systems.Īstronomers have made a groundbreaking discovery of an exoplanet whose orbit is deteriorating as it orbits an aging star. ![]() Credit: Gabriel Perez Diaz/Instituto de Astrofísica de Canarias Chontos also led 2019 effort to confirm that this object was an exoplanet, not the false positive it had believed to be for a decade. Ashley Chontos, Princeton’s Henry Norris Russell Postdoctoral Fellow in Astrophysics, was part of a team discovering that Kepler-1658b is spiraling to its doom around its aging star, providing a chance to learn more about the fate of other worlds as their solar systems evolve. ![]()
