The Goldendale Observatory Interpretive Center is located on a hilltop North of Goldendale, Washington. It is a unique facility because it caters to the general public with programs designed to educate the novice as well as the experienced star gazer. They have a number of telescopes including a 24.5 inch that is used in the evenings for public viewing sessions. There is also a library for in house study of astronomy. The facility is run by the Washington State Parks Department. Begun on July 1, 2011, admission to the Goldendale Observatory State Park is via a Discover Pass. You can find out more information on this by visiting their website or by visiting the Washington State Parks website.

Steve Stout serves as the facility supervisor and is a very knowledgeable amateur astronomer and friend of mine. He gives an interesting talk before each session and keeps the public updated on the latest happenings in the cosmos. Enjoy the Clear Sky Chart above and the weather link below. Keep in mind these are only predictions and weather conditions can change rapidly. The blue background color of this webpage is from an image taken at 6300' Table Mountain near Ellensburg.

Historical Background

The observatory is the result of the efforts of four men, M.W. McConnell, John Marshall, Don Conner and O.W. VanderVelden who built the 24.5 inch telescope. These men offered to donate the telescope to the City of Goldendale on the condition that a building be provided to house it. Funds for the building were provided by a federal grant, and the observatory was dedicated October 13, 1973. The Goldendale Observatory Corporation, a non-profit group led by a volunteer board of directors, leased the observatory from the City of Goldendale until December 1980, when the State Parks Commission purchased the site. From January 1981 to July 1981, an interim agreement between the Commission and the corporation operated the observatory. The Commission assumed full operation on July 1, 1981, and the corporation board now acts in an advisory capacity. A much more detailed history of the observatory is here. Enjoy your visit and take your time and see everything the Goldendale Observatory State Park has to offer.

Current NASA missions

There will be plenty of activity on Mars and Saturn in the next few Months. I have put a link to the Mars and Saturn Mission websites at JPL, so you may look at all the pictures from the missions. I also have a link to local viewing times for the International Space Station and the new Kepler and Dawn missions.
