Dudley’s Night Sky Adventures @ miSci

An Astronomy Educational Experience for people of all ages.

March's Theme is "Everything Moon & Preparing for April’s Lunar Eclipse"

The best way to get better at identity objects in the night sky is to learn from astronomers and to practice identifying them in relation to your surroundings and other nighttime objects.

The Dudley Observatory, miSci and the Albany Area Amateur Astronomers are teaming up to offer monthly Night Sky Adventures at miSci to give all who are interested an opportunity to practice their observational astronomy skills. Lead by Astronomy Educator, Megan Dominguez and volunteers from the Albany Amateur Astronomers, we’ll practice identifying stars, constellations and dark sky objects both through scopes (weather permitting) and in the Suits-Bueche Planetarium.

Rain or shine. Bring your binoculars and/or telescopes on clear nights (we’ll also have some scopes to share). All ages – adults and young people welcome. No experience necessary – just your interest!

Third Tuesday of the Month.

Tuesday, March 17, 2015 - Everything Moon & Preparing for April's Lunar Eclipse

Tuesday, April 21, 2015 - The Spring Sky & Lyrids Meteor Shower AND Special Mini-clinic "How to buy the right telescope for your family".  Join expert local astronomer Alan French to get practical advice on the best and most economical astronomy equipment for your family's stargazing.  

Tuesday, May 19, 2015 - Saturn at Opposition & Summer Sky Preview

No reservations required. Fee: $3 per person, $5 per family, Free for miSci members.

Union College Observatory Open Houses for 2015 dates coming soon.

Clear weather only! Please go into Astronomy classroom, room 301 on the 3rd floor of Olin Science Center, then up stairs to dome. Additional open houses and rain dates may be announced on our web page at

Viewing targets can include: the Moon, Saturn and its moons, Mars, as well as deep sky objects beyond the solar system such as double stars, star clusters, nebulae, and galaxies.

Come view the skies through our 20" reflecting telescope on the roof of the Olin Science Center! Open houses are free and open to the public.

Open houses for the general public are offered monthly, frequently timed near the first-quarter moon. These are clear-weather only events, so we are closed if there is any precipitation, strong winds, or mostly cloudy conditions. Note that with the exception of Homecoming and ReUnion weekends, all open houses are free and open to the public with no tickets or reservations required. Only for Homecoming and ReUnion open houses do we issue tickets at the Reamer Campus Center, and these tickets are free. The observatory hotline (518)-388-7100 announces the date and time of open houses as well as announces last-minute cancellations. These cancellations are often decided only 1/2 hour prior to the opening time, unless rain or fully-cloudy conditions make it obvious we cannot open.

Open houses will be canceled in the event of cloudy, rainy or snowy weather. Cancellations will be announced through the hotline at 388-7100.

The Union Observatory is located on the top of the Olin Center (off room 301), northeast of the Nott Memorial next to the Reamer Campus Center.

For additional information on the Open House or Dudley Observatory, contact Observatory Manager Francis Wilkin at (518) 388-6344 or via e-mail at College, F.W. Olin Center, 807 Union St. Schenectady, NY 12308 (518) 388-6000. Further information may be found on the observatory website

The Dudley Observatory is seeking a professional Astronomer for public outreach and education.

Click here to learn about this postion.

Fourteen films, archived for over fifty years, are making their debut on the new Dudley Observatory YouTube Channel today. The fascinating visuals of early astronomical documentaries and research materials will delight scientists and historians as well as the general public. To access the channel, go to Highlights include: Trip to the Moon, The Mystery of Stonehenge, Adirondack Visions, and The Sikhote-Aline Meteorite.

“These short films enable easy access to important, and in their time, ground-breaking experiments made by Dudley astronomers, such as Curtis Hemenway’s rocket launches,” said Elissa Kane, interim executive director. “These 14 selections show the breadth of the archive – from raw footage in the field to educational films produced mid-century. Our collection is huge, and it is our intention to release new items to the channel regularly in our role as the Capital District’s Astronomy Resource.”

In addition to the new YouTube channel, the Dudley Observatory hosts and co-sponsors internships, professional development, school and community educational experiences, and star gazing in local rural locations where viewing is best.

The Dudley Observatory was chartered in 1852, and is currently housed at miSci, in Schenectady, New York. It is the oldest organization in the U.S. outside of academia and government dedicated to the support of astronomical research, and continues to serve the Capital Region through educational programs such as star parties, inflatable planetarium programs, and astronomy program partnerships.

We wish to thank the following for their generous support of these programs!

- Stewart's Shops

- Times Union

- "Hope Fund" of The Community Foundation for the Greater Capital Region


The Dudley Observatory

We were chartered by the State of New York in 1852, is the oldest independent organization in the United States supporting research and education in astronomy and the history of astronomy. Our library contains one of the world's finest collections of historically significant astronomical texts, including rare books of Copernicus, Galileo, and Kepler.  The Dudley Observatory Archives is a fascinating collection of historical records pertaining to both astronomy and Albany.

The Dudley Observatory was founded through the generosity of those who saw our Capital Region as an economic and intellectual center, the "Tech Valley" of its day.  In the last 150 years, the Dudley Observatory has periodically changed the focus of its work to reflect the needs of the community.

During the 20th century, Dudley Observatory astronomers achieved world class status with their accurate determination of the positions and motions of more than 30,000 stars. These observations form the sole example in the history of astronomy of the precise position and proper motion determination of all stars visible to the unaided eye with a single high precision telescope.

The current focus of the Dudley Observatory is on using astronomy to promote science education, with an emphasis on education, recruitment and early career development in science and technology.  We have enjoyed a great deal of success with projects that fire the imaginations of the young, nurture them through the early stages of career development, and instill a life-long appreciation and enjoyment of science.
