Welcome to the Westport Astronomical Society

The Observatory Tower

This year the Westport Astronomical Society celebrates 41 years of bringing the wonders of the night sky to the thousands who have visited the observatory. We’re a non-profit organization of all volunteers that’s free and open to the public every Wednesday night from 8-10 pm, if the skies are clear. The Dome Observatory houses a 12.5″ Newtonian telescope and the lawn regularly hosts the newly upgraded and HUGE 25″ Obsession telescope, the largest in Connecticut available to the public.

WAS has free monthly meetings with experts at the top of their fields. We feature speakers from the Hayden Planetarium, The American Museum of Natural History, Yale, NYU, UConn, Columbia and educators from all over the globe who enrich our community with cutting edge discussions on cosmology, physics and astronomy. Additionally, there are additional special, private events scheduled throughout the year for our members and supporters.


Check out and register on our forum! Discuss the sky and upcoming events with members of the Westport Astronomical Society.

NEXT MEETING: August 16, 8:00pm

The Westport Astronomical Society’s Free Monthly Lecture Series

Coming Soon:

September 20 – Dr. Meredith Hughes – Southern Connecticut State University
Planet Formation through Radio Eyes
Dr. Meredith Hughes

Dr. Meredith Hughes

Planets form in disks of gas and dust around nearby young stars.  Radio telescopes are particularly good at exploring these planetary nurseries, because they allow us to peer deep into the dusty cocoons surrounding the young planets, as well as revealing the microwave emission from the small gas molecules that make up most of the mass of the disk.

The Atacama Large Millimeter/submillimeter Array (ALMA), the most advanced radio telescope ever built, has recently started operations in northern Chile, and it is revolutionizing our views of planet formation.  I will describe some of the ways in which we are using ALMA to unveil the planet formation process and learn about the properties of the youngest planetary systems.



December 20 – George McDonald – Mars’ Mysterious Atmosphere

Clear Sky forecast

Clear Sky Forecast for the Westport Observatory

It’s the astronomer’s forecast. It shows when it will be cloudy or clear for up to the next two days. It’s a prediction when the observatory will have good weather for astronomical observing. Hint: If you see white blocks at night near the red vertical line (midnight), there’s a good chance we’ll be closed. Click the image to refresh.
