Expanding Our Universe

Lowell Observatory is an independent, non-profit research institution located in Flagstaff, Arizona – the world’s first International Dark-Sky City.

Our mission is to pursue the study of astronomy, especially the study of our solar system and its evolution; to conduct pure research in astronomical phenomena; and to maintain quality public education and outreach programs to bring the results of astronomical research to the general public.

Sharing Our Discoveries

Lowell Observatory was founded in 1894 by Percival Lowell.

Since then, Lowell astronomers have discovered Pluto, collected the first evidence of the expanding Universe, and measured the motions and properties of stars, among many other achievements. Today, we continue to do research in all areas of astronomy and  share our discoveries with all.
