What is the Slipher Society?

Slipher Society members invest annually in Lowell astronomers and their research. The Society is named in honor of two of the observatory’s historic directors, brothers V.M. and E.C. Slipher. (Find out more about the Slipher brothers here.)

Members of the Slipher Society support Lowell’s mission to study our universe. They recognize the need to fill critical gaps between grants and other formal funding sources. They jumpstart new efforts and help complete current research projects. Slipher Society members become co-discoverers of the wonders that Lowell Observatory astronomers share with the public.
