Second Sundays Stargazing at Pioneer Works

On the second Sunday of each month, this former ironworks turned art-and-science center throws open all three floors and its back garden for a free open house. The Amateur Astronomers Association of New York and astronomers from Columbia regularly haul telescopes into the garden for solar viewing by day and stargazing after dark, weather permitting. It is a genuinely odd mash-up: open artist studios, live music, and a refractor pointed at the sky in industrial Red Hook.

The move: Wander the open studios and live music, then queue at a garden telescope to take turns squinting at the rings of Saturn.

📍 Before you go Free; monthly only (second Sunday); stargazing is weather-permitting and cancelled if cloudy or raining.
