Wyoming Infrared Observatory

Wyoming Infrared Observatory is a research facility on Jelm Mountain with a 2.3-meter telescope positioned at about 9,656 feet elevation. The site was chosen for its dark skies and dry air, which create ideal conditions for observing infrared radiation from space.

The facility began operations in September 1977 with support from the Wyoming State Legislature and the National Science Foundation. In its early years, it housed the world's largest working infrared telescope and led to major discoveries in infrared astronomy.

The facility represents a hub where university researchers and visiting astronomers work together to study the night sky. Its role in the scientific community shows how a mountain location can serve serious study and collaboration.

Visitors can request observing time through the University of Wyoming, with availability allocated in quarterly cycles. Those planning a visit should contact the university first and be prepared for changeable mountain weather at this elevation.

Between 1977 and 1980, this was the world's largest working infrared telescope, a status that defined the observatory's early years. This period of technological leadership enabled groundbreaking research in infrared astronomy that fundamentally changed how we understand the universe.
