A selective critical checklist of notable Wednesday TV:

The Mueller Hearings (8:30 am/7:30c, many channels): Chances are you've heard of, but perhaps not read, former Special Counsel Robert Mueller's report on Russian interference in the 2016 election and investigation into whether the president obstructed justice. In a long-awaited spectacle of political theater, Mueller will take questions in hearings before the House Judiciary Committee for three hours and (at noon/11c) the House Intelligence Committee for approximately two hours. Most major networks and all news channels will provide complete coverage from Washington, D.C.

The Paramount Network series returns on June 19.

The Last Cowboy (11/10c, Paramount Network): I suspect many fans of Paramount's dark contemporary Western Yellowstone are like me and enjoy the scenes with the rugged cowboys even more than the blistering domestic drama. Doubling down on this aspect, series creator Taylor Sheridan presents a companion piece in an unscripted series following eight men and women who compete in the arena of professional reining, which honors the cowboy tradition as they guide horses through a series of exacting circles, spins and stops. The series builds to what is being billed as the largest competition in the sport's history — "The Run for a Million," scheduled for August in Las Vegas — which will be showcased in the season finale.

The Planets (9/8c, PBS, check local listings at pbs.org): PBS's signature science program Nova goes beyond our current fascination with the moon to take viewers through the vast solar system. The ambitious five-part series studies each of the planets in fascinating detail, featuring CGI imagery and footage captured by orbiters and rovers. Narrated by Zachary Quinto (Spock in the new Star Trek movie franchise), the first hour explores the "Inner Worlds" of the planets closest to the Sun: Mercury, Venus, Earth and Mars — with the latter the focus of the second hour, charting Mars' evolution from a blue water-world to a frozen desert planet.
