Rice University Campus Observatory


The Rice Campus Observatory is used primarily as a teaching facility for undergraduate education.  Classes which make use of the observatory include Astr 201: Stars, Galaxies, and the Universe and Astr 202: Exploration of the Solar System, both introductory classes for non-science majors; Astr 221: Observing the Night Sky, a new lab class for students in all academic programs; and Astr 230: Astronomy Lab, the primary course for Astronomy majors and others to learn to use a research calibre telescope and equipment including spectrometers and CCD imagers.  Students in Astr 230 also learn advanced image processing techniques such as IRAF which they use on data taken at the campus observatory to do a final research project.

Observatory Location:

The Rice University campus observatory is located on the north side of campus, to the west of the North Parking Lot and on the north side of the intrmural fields.  It is most easily accessible from entrance 13 off of Rice Blvd.  The linked map shows the location on campus marked with a red dot.  Please Note: There is a charge to use the visitor parking at Entrance 13, payable by credit card only. For major events this parking may fill up, but visitors can then use the Stadium parking lot about a half mile away. The Campus shuttle bus services the Stadium lot; ask the driver to direct you to the closest stop to the observatory.   Note, all campus shuttles stop running at 10:40 pm, so keep this in mind when planning your trip.  The above map is taken from the Rice University campus parking map, which is an interactive map you may wish to consult if you are driving to campus.  The only free parking for non-Rice visitors is available on the west side of the football stadium, quite a distance from the the observatory.

August and September Open Houses: Here comes Mars!

Mars makes its closest approach in 60,000 years, so we are opening the observatory each evening the first week of class and will have additional public nights throughout the rest of the semester.  Check below for the currently scheduled public viewing nights.  In addition, views of star clusters, nebulae, and other celestial objects will be had.  Come out and join us.

Fees: Unless specifically noted as Rice only above, the open houses are available to anyone.  Aside from parking described above, there is no fee to attend the observatory open house.

Note on Times and Weather: In late August it gets dark enough to observe some objects around 8:30 pm; however, Mars is so low on the horizon that its view is highly distorted by the Earth's atmosphere.  As a result, we will delay viewing of Mars through the large telescope in the dome until after 9:00 pm.  On well attended public nights, visitors will be required to sign in at a check-in table set up in the parking lot to look through the large telescope in the dome.  In addition to this telescope, there will be 2-3 or more smaller telescopes set up in the parking lot for viewing.  These smaller telescopes do not require sign in.  On Sept. 10 and 12, sign in will begin about 7:30 pm, weather permitting.  The weather pattern has been for clouds and haze during the day, but it often becomes partly cloudy after sunset. Our experience has been that the large telescope is able to see Mars and the Moon well through thin clouds, and if it is clear we get good views from the smaller portable scopes as well. If the Moon is out, we will get some wonderful resolution with the main telescope.  As many of you may know, Mars is getting closer to Earth this August than it has at any time in the past 60,000 years.  However, it is not going away soon.  Excellent views of Mars will continue to be available into October.

On public nights the observatory will open at 9:00 pm and will stay open until at least 11:00 pm.  If there is still a crowd at closing time, the observer can remain to accomodate people still signed in, but we also need to go home eventually.  If you are not present when your group is called, there is not guarantee you will be able to look through the large telescope.

Houston is plagued by poor weather much of the time, especially in the Summer.  On the nights of the observatory open houses, check back here between 7 and 8 pm or later to make sure it will not be cancelled due to poor weather.  If it is raining, the observatory will be closed.
