The stars were out at the planetarium last night. Jennifer Lopez and Marc Anthony, Venus and Serena Williams, Mary Kate and Ashley Olsen, Isabella Rossellini, and Kate Moss were among those who turned out to celebrate the 100th anniversary of Coty at the American Museum of Natural History’s Rose Center for Earth and Space.

The New York-based perfumerie, founded by Francois Coty in 1904, produces Ms. Lopez’s fragrance, Glow by J. Lo, as well as Ms. Rossellini’s Isa Bella and Manifesto.

A cadre of Fashion Weekers trekked to the Upper West Side to attend. Those partying among the meteorites included designers Kenneth Cole and Anand Jon, 1980s supermodel Carol Alt, and 7th on Sixth director Fern Mallis, who talked with Siberian stunner Irina Pantaeva. Angie Everhart, Veronica Webb, and Gemma Kidd also upped the beauty factor in an already glamorous crowd. The ubiquitous Patrick McDonald wore a kimono and his sidekick, Kenny Kenny, in black and silver glitter, looked like he wanted to prove to those pesky scientists at the museum that there is, in fact, alien life.

Actress Bai Ling, who can be seen in “Sky Captain and the World of Tomorrow” with Jude Law, Gwyneth Paltrow, and Angelina Jolie, wandered about.

Approaching the event, one could see the flurry of popping flashbulbs from several blocks away. Among those more interested in seeing than being seen were Village Voice Michael Musto of the Village Voice, Steven Cojocaru of People magazine, and Metro Television’s “Full Frontal Fashion” host Robert Verdi. Mr. Verdi will be working the red carpet at the Emmy awards on Saturday for the E! network, having recently taken over for Joan Rivers and her daughter Melissa.

There were a smattering of New York social types, notably Johnson & John son heiress Casey Johnson, author Tama Janowitz, Amy and Andy Hilfiger, and Ronson-mom Anne Dexter-Jones, whose son Marc spun dance favorites from behind the turntables.

The catering had a lab-geeks-meet-jocks flair, with drinks such as watermelon-flavored shots served in test tubes.
