The Theodor Jacobsen Observatory is the second-oldest structure on the campus. Built in 1895, the Observatory with its 120-year old, 6-inch refracting telescope is still offering celestial views of the wonders of the Universe. Here you will find information on opened nights, making reservations, a history of the telescope, a history of astronomy at the UW, and even an operating manual for the telescope. Come join us in a tour; there is no charge to learn about and view the night sky!
TJO Evening Public Talks
The majority of the talks of the open house season are given by undergraduates at the University of Washington, individuals who are either majoring in physics and astronomy or are in other majors but really enthusiastic about astronomy. The level of the talks varies with the topic. Some are geared more to the younger visitors; most are geared for high school level. Please come and lend your support. By being in the audience you will be taking part in the educational program at the UW.
The talks on a given evening start approximately 5 minutes after opening and take place in the classroom that adjoins the Observatory. If the sky is clear enough, the dome will be open for viewing celestial objects through the ancient telescope. Reservations are strongly recommended for the talks, and visitors with reservations have priority viewing in the dome after the talks finish; no reservations are needed to tour the Observatory and take part in the exhibits, activities, and viewing through telescopes available on the Observatory grounds.

The topics and abstracts for the 2017 observing season are listed below. Thank you for all of your interest this past season, and we look forward to another successful series of undergraduate talks and observing of celestial objects. These talks generally last between 20 and 30 minutes, giving us plenty of time to view celestial objects if the night skies are at all clear.
June 7, 9:00 pm – Steven Huynh, student in our outreach course, will be giving the talk on “Rockets, Space Missions and Astronauts.” He will be covering the history and fundamentals of space flight and what it is like being an astronaut. [[The classroom is now full for this talk; no more reservations available.]]
June 21, 9:00 pm – Arthur Vantanyan (math major and former student of the outreach course) will be talking about the possibility for life on other worlds.
[[Apologies:The classroom is now full for this talk; no more reservations available.]]
July 5 – Open house cancelled for this evening as all of our volunteers will be away.
July 19 – 9:00 pm – Aislynn Wallach (astrophysics major and former student of the outreach course) will be covering the latest discoveries of exoplanets – those worlds orbiting other stars.
August 2 – 9:00 pm – Aleezah Ali (astrophysics major and former student of the outreach course) will give an overview of binary stars – spectroscopic, eclipsing, wide orbits, and chance alignments. If clear, we will try observing Mizar (a 6-star system consisting of 3 binary stars, located in Ursa Major).
August 16 – 9:00 pm – Wil Sanctis (human-centered design and engineering major and former student of the outreach course) will be giving a talk on exoplanets, specifically those that lie within the habitable zones of their stars.
September 6 – 8:00 pm – Ellis Avalone (astrophysics major and former student of the outreach course) will have spent the summer as a research assistant studying the corona of the Sun. Her talk will be about the Sun.
September 20 – 8:00 pm – Bayu Wilson (astrophysics major and former student of the outreach course) has plans to explain what cosmology is and give an overview of the Universe as we now know it.
We apologize for not being able to accommodate everyone who wants to visit the Observatory and take part in the talks given by UW undergraduates. The classroom holds only 45 people; the dome that houses the 1892 refracting telescope can have a maximum of 12 adults at a time. Visits to the dome and discussions with Seattle Astronomical Society members last about 10-15 minutes. “Tickets” (which are free) to visit the dome are distributed in the order in which reservations for the talks are received.
Seattle Astronomical Society members operate the ancient refracting telescope in the dome and can find fascinating treasures of the night sky. Their members are an endless source of information and enthusiasm about astronomy.
Reservations are strongly recommended for the talks as the TJO classroom holds only 45 people. Those with reservations have priority viewing for the dome. While all are welcome to visit without reservations, please note that only the activities and the smaller telescopes set up in the Observatory grounds will be available. Usually for the July through September open houses, those without reservations do not get to visit the dome until close to closing time.
We are currently taking reservations through email only. Please email Dr. Ana Larson <<firstname.lastname@example.org>>, Observatory Director, with the date you would like to attend and how many people will be joining you.
Group & School Reservations
We are especially glad to welcome student class and home-schooling groups to our observatory and can work with the teachers on topics that they would like presented. We also have a wide variety of activities and labs that we could include in the evening’s program. Please email Dr. Ana Larson, Observatory Director, with the date you would like to attend, the size of your group, and any further questions you may have.
We are located at the north end of the University of Washington campus, just east of the Burke Museum, at the intersection of NE 45th Street and Memorial Way (17th Avenue NE). If you are coming from:
- Eastside: Take 520 W to Montlake Exit. Left at 2nd light (on to Pacific). Come to 15th Avenue NE and make a right. The Physics/Astronomy building is on the corner, but this is NOT where you want to go. Continue up 15th Avenue NE until NE 45th Street. Take a right and continue east. You will see the Burke Museum on your right. Take a right at the next intersection. You will be going south on Memorial Way. If the parking gates are open (Gate 2), you will need to stop and get a permit. Lots N1 and N5 are the closest to the Observatory.
- North or South: I-5 to NE 45th Street exit (University of Washington). Take NE 45th Street East until you see the Burke Museum on your right. Take a right at the next intersection. You will be going south on Memorial Way. If the parking gates are open (Gate 2), you will need to stop and get a permit. Lots N1 and N5 are the closest to the Observatory.
The University of Washington has lots of information on parking on campus for school and other bus transportation. Please visit the UW Parking Services web site for complete instructions and contact/permit information. If you are coming by car or car pool and it is earlier than 9 pm, then you will need to check in with the gate keepers at the north entrance (Gate 2) to the U of W campus for a permit and directions.
