Plan Your Visit

The Space Telescope Science Institute (STScI) is a campus of offices in Baltimore, Maryland. Shuttles and walking paths connect our locations: the Steven Muller Building, the Bloomberg Center for Physics and Astronomy, and the Rotunda. They are all on or near the Johns Hopkins University Homewood campus.

We aim to make everyone’s visit more comfortable and enjoyable, while helping you fully engage in a conference, workshop, or lecture. Please reach out to ask questions or share which accommodations, access tools, or assistive technologies you will need to facilitate your participation in activities while at STScI.

Please note that we do not currently offer public tours of our offices. However, the lobby area and café on the main level of our Muller building are open to the public. The hours of the café are 8 a.m. to 2 p.m.
