Rhode Island’s own contestant on “RuPaul’s Drag Race” continues her summerlong run at P-town’s Harbor Hotel, where she hosts a Sunday brunch with enough sequins to dazzle the cobwebs out of your Saturday night. A year ago Haley revealed her daily persona to her devoted online following: “I wake up, I eat breakfast, I put my pants on the same way.” No time for breakfast on Sundays, though, when Ms. Star takes Commercial Street by storm. She often credits her late father for his wisdom — “Live each day as if it’s going to be your last” — which has led to some fabulous content for her YouTube channel, including that time she went skydiving. Until brunch. . . peace, love and cupcakes!


11-1 p.m. 698 Commercial St. $12.95. www.harborhotelptown.com

He will share the stage with coheadliner Gavin DeGraw, another pop songwriter with a penchant for well-chosen cover songs. DeGraw has his own local connection: The New York native attended Berklee, however briefly, in 2002.

In “The Big Oyster: History on the Half Shell,” the estimable Mark Kurlansky explored the previously unheralded role of the oyster in the development of New York City – how the lowly bivalve became the city’s most popular export and its natural filtration system.

Shucking lesson included.

“The City Dark: A Search for Night on a Planet That Never Sleeps”

The Maria Mitchell Association’s observatories offer fantastic views of the stars, in honor of Mitchell, the Nantucket native who was the first woman to work as a professional astronomer. Unimpeded views of our universe are becoming as distant a reality as Mitchell’s 19th century, as the electric sprawl of civilization robs us of the night sky. The MMA hosts this special viewing of “The City Dark: A Search for Night on a Planet That Never Sleeps,” an award-winning 2011 documentary that poses a simple question: What do we lose when we lose the night?

7 p.m. Tuesday. 33 Washington St., Nantucket. Free. http://www.mariamitchell.org/
