The offices of the Observatories of the Carnegie Institution for Science are located at 813 Santa Barbara Street, Pasadena.

Our colloquia are held in the William T. Golden auditorium at 4:00 p.m. on Tuesday afternoons, preceded by refreshments at 3:30 p.m.


Colloquium speakers are normally housed in the Atheneum, on the Cal Tech Campus (551 South Hill Avenue), or the Guest Center at Fuller Seminary (700 Locust Street). Both are within walking distance of the Observatories.


A common choice for transportation is to employ a shared-ride van between LAX and the airport.  You can make reservations for one of the two operators:  Prime Time Shuttle and Super Shuttle.  Both offer similar quality service for roughly $30 each way.  Taxi service is roughly $90 each way. Uber and Lyft are are now permitted to pick up and drop off at LAX and will cost around $45, depending on demand.

There is also the FlyAway shuttle service between LAX and Union Station.  From Union Station, one can take the Metro Gold Line to the Lake Ave. station, which is a short walk from the Observatories. Detailed instructions can be found here.
