Caveat, the Lower East Side theater and comedy venue, hosts the Carnegie Science Spooky Social on Thursday, October 29. The full title is "Planet X, Killer Asteroids & Other Things Lurking in Space," and it is a Halloween-season evening organized by Carnegie Science, the research institution.

The centerpiece is a talk by astronomer Dr. Scott Sheppard. The poster bills it as a fun, Solar System-spanning talk. The subjects are the title's hidden planets, including the long-theorized Planet X, and asteroids that could threaten Earth, along with other objects lurking in space.

The night goes beyond a lecture. The program adds treats, trivia and prizes, and there is a costume contest that guests can enter if they like. Dressing up is optional, so the event works as a science talk with a Halloween theme layered on top.

Doors open at 6:30 p.m. and the show starts at 7 p.m. Tickets are $17.85 with a discount code, according to listings. Caveat runs science-minded comedy shows on other nights too, including its Science Tonight series, so the venue is a natural home for this kind of format.

For Japanese readers and other visitors, it is a way to spend a Halloween-week evening at a local New York venue rather than a standard tourist attraction. The event is aimed at anyone curious about astronomy who wants the material delivered in a relaxed, social setting.
