Historical Overview

Founding and Early Development

Established in 1790 by Ferdinand I of the Two Sicilies, the Observatory was designed to elevate Palermo’s scientific standing. Its first director, Giuseppe Piazzi, equipped it with advanced instruments like the “Palermo Circle” by Jesse Ramsden, marking the start of a distinguished history.

The Discovery of Ceres

In 1801, Piazzi discovered Ceres, the first asteroid, cementing the Observatory’s international reputation and contributing significantly to astronomical science.

Scientific Achievements

Stellar Cataloguing: Piazzi’s 1803 star catalogue became a European reference point.
Solar and Stellar Physics: Under Pietro Tacchini, solar spectroscopy flourished.
Modern Research: Now part of INAF, the Observatory participates in cutting-edge studies of solar coronae, stellar evolution, and supernova remnants (INAF Palermo Research).

Instrumentation

Historic instruments on display include the Ramsden Circle, a meridian circle from Berlin, and a 25-cm Merz equatorial telescope. The Observatory’s horological collection is internationally significant, with artifacts from British, Swiss, Austrian, German, French, and Italian makers (AHS Blog).
