Tour the beautiful grounds with friendly, knowledgeable guides and experience the universe though widescreen multimedia shows, exhibits, live presentations, and SlipherVision, an immersive space theater.

View the moon’s craters and Saturn’s rings through the 32-foot-long Clark Telescope. And peer through the legendary Pluto Telescope, which helped 24-year-old observatory assistant Clyde Tombaugh discover Pluto in 1930. 

“Of all the planets, only Pluto was discovered in this country, so it’s a neat piece not only of scientific history but American history,” says Kevin Schindler, Lowell Observatory’s historian.

The interactive Space Guard Academy exhibit also is popular, as is Junior Astronomer, a program that allows kids to fill out a packet on-site and receive a patch.
