Guyon

French jockey Maxime Guyon placed third with outsider Onesto.

As the Roman leader at the heart of the play, Alban Guyon, dressed in either leather pants or a tracksuit with a gold chain, swaggers and shouts to exhausting effect.

"The conventional thinking is that most - if not all - planets form by slow accretion of solids onto a rocky core, and that gas giants go through this phase before the solid core is massive enough to start accreting gas," said astronomer and study co-author Olivier Guyon of the Subaru Telescope and the University of Arizona.

"This process cannot form giant planets at large orbital distance, so this discovery challenges our understanding of planet formation," Guyon said.

"New astronomical observations continuously challenge our current theories, ultimately improving our understanding of the universe," Guyon said.
