AMERICA’S GOT TALENT: THE CHAMPIONS 8 p.m. on NBC. This spinoff of Simon Cowell’s popular talent show closes out its second season with 10 franchise favorites vying for the title “ultimate champion.” The finalists, all acts that did well on previous seasons of “America’s Got Talent” or international versions of the program, include Alexa Lauenburger, whose dog act won the 2017 German competition, and Marcelito Pomoy, the winner from the Philippines in 2011. The dance group V. Unbeatable, a favorite of the judge Howie Mandel, and Sandou Trio Russian Bar, whose acrobatic performance last week was a standout, are also in contention.

THE EXPANDING UNIVERSE OF ASHLEY GARCIA Stream on Netflix. There is no outrunning adolescence, even for science prodigies. Ashley (Paulina Chávez) spent her childhood becoming the “youngest person ever to earn a Ph.D.” but when the 15-year-old moves to California to do robotics work for NASA she finds herself facing the same problems as her peers, especially when it comes to romance. Ashley’s uncle Victor (Jencarlos Canela), a high school sports coach, isn’t prepared to parent a teenager, but her friend Brook (Bella Podaras) is there to pick up the slack, or at least guide her through traditional coming-of-age rituals like spin the bottle. .
