Double Stars

The observatory routinely obtains images of double stars to derive their separation and position angle (relative positions to each other) in support of maintaining the Washington Double Star Catalog through the Journal for Double Star Research.

Minor Planets

The observatory collects follow-up data on minor planets (asteroids) to better understand their orbits.  This data is sent to the Minor Planet Center for analysis.  In the pursuit of these images, it is hoped that a "chance" undiscovered asteroid will also be imaged and reported to the MPC.


While some imaging of comets is performed to get "pretty pictures", the main use of these images is to determine photometry that measures how the brightness of the comet changes over time and derive precise positions - astrometry.  The photometry and astrometry data is reported to the Minor Planet Center and other organizations.


Astrometry involves getting precise co-ordinates of objects such as comets and minor planets (asteroids) relative to the "fixed" background stars. These observations are reported to the to the Minor Planet Center via specially formatted e-mail.


Research at the observatory focuses on imaging transient phenomena associated with:

About the Observatory

Newcastle Observatory was constructed in October, 2004, and is privately owned and operated. Since it's inception, the observatory has been under active development and operation; primarily conducting research by imaging transient phenomena such as variable stars, gamma ray bursts, and astrometry of comets and minor planets (asteroids). The observatory collects and distributes photometric and astrometric data to various organizations, including:

Welcome to Newcastle Observatory

Computing facilties at the observatory are used to contribute toward the following distributed computing projects.

Helping Hubble

The Space Telescope Science Institute's Hubble Heritage Project, used data supplied by Newcastle Observatory through the AAVSO to image "the star that changed the universe".  It is a Cephied variable designated "V1" by Edwin Hubble that he imaged in 1923 with the 100 inch Hooker telescope atop Mount Wilson, California.  This was the first variable star used by Edwin Hubble to determine the true scale of the universe.
