projectBlueBookFrom producer Robert Zemeckis, director of “Back to the Future” and “Contact” among other films comes the new series “Project Blue Book” (History, 10 p.m.), about the phenomenon of UFO sightings in the late 1950s and early ‘60s.

The reliable Aidan Gillen (Littlefinger on “Game of Thrones”; Tommy Carcetti on “The Wire”) plays a scientist hired by the government to mostly debunk thousands of claims from the public of UFO sightings, but he’s not so sure.

Democrats will follow with a response. And fact checkers will be working overtime.

“Legend Hunter” (Travel, 10 p.m.) looks into the Lizzie Borden case.

New seasons start for Tyler Perry’s soapy “The Haves and Have Nots” (OWN, 9 p.m.), “Garage Rehab” (Discovery, 8 p.m.), “What on Earth” (Science, 9 p.m.) and “How the Universe Works” (Science, 10 p.m.).
