The South Fork Natural History Museum in Bridgehampton will host "What's Up in the Sky?" on Thursday night at 7. This summer, the moon will cover Spica, one of the brightest stars, and Jupiter and Mars will "rendezvous" in the sky.
William Francis Taylor, the Hamptons Observatory's senior educator, will share how to view these solar spectacles, as well as summer constellations such as Sagittarius and Cygnus. The evening will conclude with outdoor stargazing, weather permitting. A Zoom option is also available, with a link at sofo.org.
John Shemilt, a purple martin expert, will be on hand on Saturday at 10:30 a.m. to show off "the colony of man-made gourds that house SoFo's newest population of purple martins," according to the museum, allowing visitors to see the newly laid eggs. The fee is $15 for adults, $10 for children. Members can take part for free.
