SOCIETY FOR ASTRONOMICAL SCIENCES

Uniting Great Minds Through Our Symposium for Astronomers

At the Society for Astronomical Sciences (SAS), we believe that anyone with a passion for discovering knowledge can contribute to scientific research, including backyard astronomers. Through cooperation between amateur and professional astronomers, we can make great strides in the study of planets, stars, galaxies, and more.

To bring together knowledgeable individuals who share a thirst for learning about the universe, we conduct an annual symposium for astronomers. At this gathering, amateurs and professionals from around the world discuss a variety of topics, such as photometry, spectroscopy, and so much more. Become a member and register to attend this premier event.

Sharing Knowledge

We provide newsletters and proceedings from our symposium. Through these resources, we help amateur and professional astronomers who use small telescopes and modern instruments to conduct astronomical research in various areas.

The 2022 Symposium will be held in Ontario, California on June 2-3-4, 2022, as a “hybrid” event:  in-person, with live web broadcast.

Science With Small Telescopes

Telescope
Amateur and professional astronomers are using small telescopes and modern instruments to conduct astronomical research in a variety of areas.
  • The size, shape, and rotational state of asteroids are determined by occultations and light curves.
  • Continuous monitoring of planets provides context between large-telescope and spacecraft observations.
  • Light curves of eclipsing binary stars and astrometry of visual double stars contribute to the assessment of stellar size and mass.
  • Modest-resolution spectroscopy of transient objects can distinguish supernovae from imposters.
  • Time-series photometry provides a wealth of data about variable stars.
  • Long observing runs and exploratory projects that are impractical at large observatories can be pursued on small telescopes with astrometric, photometric, and spectroscopic capability.
