Astronomy is the theme for week four of Thomaston Public Library's 40 Days of Summer kids' program.

The program, organized around weekly themes, features daily activities and events, a story or two, and some fun in the sun, including a picnic lunch outside, weather permitting. Each day's fun happens between 11 a.m. and 1 p.m., Monday through Friday.

Here's what's happening during Astronomy week:

Monday, July 14: Constellation Quilt — Create a constellation and make a night sky with fabric and construction paper.

Tuesday, July 15: Mythology Story and Sky Drawing — So many planets and constellations derive their names from Greek and Roman mythology. Create a myth and draw a constellation or planet.

Wednesday, July 16: Papier Mâché Planets — Get those hands all sticky and gluey building new or existing planets out of papier mâché.

Thursday, July 17: Northern Stars Traveling Planetarium will visit from Fairfield and present two live storytelling programs featuring Native American sky legends and Greek and Roman myths about the stars and constellations.

Friday, July 18: Papier Mâché Planets, Part 2 — Finish the papier mâché planet and then paint and decorate it.
