For those of you joining us for the star party at @DiscoveryGreen tonight, please bear with us. The lawn is closed so some of our volunteers are by the stage. Others are trying to find parking in order to unload their telescope and get set up, but that’s been a challenge tonight.
We can't wait to be out at beautiful @DiscoveryGreen for our September Star Party! Join us from 8 p.m. to 10 p.m. on September 7 - it's free and fun!
Stargazing with @HoustonAstroSoc is a popular event at Discovery Green. Don’t miss the opportunity to learn more about the moon & various deep-sky objects, Sept. 7 from 8 p.m. to 10 p.m. H.A.S. volunteers will have telescopes in tow for the free event. Clear skies are required.
