Worlds Revealed

Academic freedom is essential to scientific research.

Lowell Observatory is an independent non-profit research institution that has pursued its mission of astronomical discovery since 1894. Today, our staff of astronomers and planetary scientists continue the work of revealing our universe with unparalleled academic freedom and access to advanced instrumentation, including the observatory’s own 4.3-meter Lowell Discovery Telescope.


Areas of Research

Our Look into the Solar System

Solar System

Planetary scientists continue a long tradition of studying bodies in the solar system, including the Sun, planets, moons, comets, meteors, asteroids, and Kuiper belt objects.

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.

"Lowell Observatory—Worlds Revealed"

Percival Lowell began using this seal shortly before his death in 1916. It shows the 24″ Clark Refractor and its dome, one of Lowell’s drawings of Mars, and a formula used to calculate perturbations in a planet’s orbit.

A Tradition of Cutting-Edge Research

Lowell has been at the forefront of astronomical research for well over a century, with critical discoveries made from the inner solar system to the far reaches of the universe. The first detection of the expanding universe and the discovery of Pluto are but two of the foundation blocks upon which Lowell’s legacy of research has been built.
