The Miami Planetarium opened its doors to the public on November 4,1966 and has entertained and educated children of all ages about astronomy and the wonders of the night sky ever since.The Planetarium houses a 67footdiameter domed (圆顶状的) projection screen with 250 seats.At the heart of the Planetarium is a SPITZ “Space Transit Planetarium” star projector (投影仪)，which is capable of accurately reproducing the stars and planets as seen from anywhere on Earth at any time during the year.Unlike any other in South Florida，the Planetarium is a unique setting for bringing the stars and planets indoors in animated live star shows and musicfilled laser light shows.
The Weintraub Observatory (天文台) houses two powerful telescopes.The visit time is from 8:00 p．m.to 10:00 p．m.. Look through the telescope to view the planets，the four moons of Jupiter，the rings of Saturn and deep sky objects such as galaxies，nebulae and double stars.
