Stargazers will go gaga over this kid-oriented science and technology center in the Oakland Hills with loads of exhibits on subjects such as space travel and eclipses, as well as cool planetarium shows. When the weather’s good, check out the free Friday and Saturday evening viewings (7:30pm to 10:30pm) using a 20in refractor telescope.

　　Admission is just $5 on the first Friday evening of each month (6pm to 10pm), when the museum organizes hands-on activities, science demonstrations, movies and night hikes.
