Learning About Our Neighbors

Galactic & Extragalactic Astronomy

V. M. Slipher’s observations of the redshifts of galaxies a century ago were the first evidence for the expansion of the universe. Research on structures of galaxies and of the universe continues at Lowell today.

The Tools of Astronomy

Instrumentation Research & Development

Our instrumentation team carries out a variety of work in support of research instrumentation, outreach telescopes, and historic preservation projects.

The Tools of Astronomy

Lowell Observatory is an independent, non-profit research institution founded in 1894 by mathematician and astronomer Percival Lowell. Today, our mission is to pursue the study of astronomy, conduct research, and bring astronomical education to the public.
