Some of the most important astronomical discoveries in history have been made at Lowell Observatory. Established in 1894, it is one the oldest observatories in the United States. Among other instruments, it is the home of the original, 19th-century Clark telescope and the famous astrograph used for discovering Pluto in 1930. During the day, the solar telescope allows you to take a close look at the sun, while at night you can view the stars, the moon, and the planets. Some programs might not be available at the time of your visit, due to weather conditions. The observatory is located at an altitude of 2,194 m (7,200 ft) and the sun can be very bright during the daytime while nights can be pretty cold, so don’t forget to bring sunscreen and dress in layered clothes.

Lowell Observatory reviews
The observatory is full of amazing photos of the years of its discoveries. Tours are given and talks are given in normal times. SO very well done and not boring! more »
My wife and I visited late last October as part of an Arizona vacation. As an amateur astronomer, this is one place I just had to visit. Lowell Observatory is most famous for the "discoveries" of... more »
I really wanted to enjoy this place since I’ve been interested in astronomy since the 60s. We arrived in the afternoon just in time to catch the last 10 minutes of the sun observations. The staff member (I don’t remember his name) was friendly, informative and interesting. Then we caught the Lowell Tour, which I though would be an overview of the facilities. But we spent 15 minutes listening to Lowell biographical trivia in the auditorium, followed by a short walk to the telescope and another 30 minutes of Lowell trivia. Not a whole lot of astronomy or telescope information in there. The museum was interesting but all the other telescopes were locked (and I didn’t want to do another tour). Maybe next time we’re in town, we’ll try the evening programs.
Very interesting that Pluto was discovered in 1916. Mr. Lowell spent his life at the observatory developing a telescope to observe space and map the planets and stars and galaxies. A mausoleum was constructed by his wife 6 years after his death and he is interred in the mausoleum on the observatory property. The original telescope and observatory are on site and are part of the tour. A night tour brings you to another observatory where you can observe the universe through a powerful telescope. Mist go to place just for the history alone.
