You can subscribe to the Bell Museum's Astronomer's Update and have it delivered directly to your email inbox! Or, you can be lazy and come here or to the budding calendar, and I'll tell you what's going on.
It not only lists events happening at the Bell Museum but events happening out in the skies, like the dwindling of the Big Red Spot on Jupiter and that on June 24, Venus will be really close to the crescent moon with Pleiades to the upper left. Set your alarm for 4:30 a.m., people! Or, if you're really lucky and have insomnia, like me, you can force yourself out of your trying-to-get-back-to-sleep rage space and stumble outside.
June's update is here.
