Sky’s the Limit Observatory and Nature Center will hold its weekly star party Saturday night, September 3. The event begins at 8 p.m. and will end about midnight, but you are encouraged to come when you can and leave when you want. Highlights will be Mars and Saturn, but visitors will also be able to see the Lagoon and Swan Nebulae, and Wild Duck cluster, along with the return of the Great Andromeda Galaxy. Sky’s the Limit Observatory is located on Utah Trail, just north of the Twentynine Palms entrance to Joshua Tree National Park.
