Eggers & Higgins Eggers & Higgins was a New York architectural firm partnered by Otto Reinhold Eggers (August 4, 1882 – April 23, 1964) and Daniel Paul Higgins (September 12, 1886 – December 26, 1953). The architects were responsible for the construction phase ...

Morehead had to travel to Sweden, where he had previously served as American ambassador, to purchase a Zeiss Model II to serve as the heart of North Carolina's new planetarium. ''Let There Be Light'' was the planetarium's first show.

Fulldome planetarium

Morehead's planetarium seats about 240 people, with a dome that is in diameter and tall. It currently has two different projection systems.

Funding for the new system was provided by

, and the planetarium's star theater is now named the GlaxoSmithKline Fulldome Theater. Morehead's historic star projector, a Carl Zeiss Model VI, was installed in 1969 and remained in limited use as of April 2011, primarily for field trip groups. This projector displays about 8,900 different stars on the dome overhead. The analog planetarium shows are a combined effort of the Zeiss projector, slide projectors and video projectors working together to form a multimedia experience. Planetarium officials hope to display at least a portion of the projector somewhere in the center. The projector was removed in August 2011.


Exhibits

On February 23, 2007, Morehead opened its first interactive exhibit, ''Zoom In: Science at the Extremes''. It features current science at the extremes of size and scale, including research done by UNC scientists. ''The Ancient Carolinians'' opened on November 17, 2007. This exhibit explores the lives of the first people to live on the land now known as North Carolina, interpreting the use of 10,000-year-old artifacts from the Hardaway archaeological site. This exhibit is supported in part by the Alcoa Foundation, which donated the artifacts to the university. After January 1, 2009, the exhibit installation was removed so that ''The Ancient Carolinians'' could become Morehead's first traveling exhibit.


Science stage

Morehead Planetarium and Science Center offers live, educator-led programs in its Science Stage. ''Science LIVE!'' shows present the foundations of science, on a variety of topics, through experiments and demonstrations that often involve volunteers from the audience.


External programs

The DESTINY Traveling Science Learning Program, which was founded by UNC in 2000, became part of Morehead in 2006. The PLANETS Portable Planetarium Program brings the fulldome planetarium experience to elementary schools that are too far from Morehead to plan a field trip to the center.


Jupiter Fellowship

Each year, the Jupiter Committee (a volunteer group that assists in planning the Jupiter Ball fundraising gala for Morehead) awards the Jupiter Fellowship. This award goes to the student employee(s) who submits the best proposal for a Morehead program, activity or innovation. The fellowship funds the implementation of the proposal.


Morehead Observatory

Morehead Observatory, located on the east end of the top floor of the Morehead building, houses a Perkin-Elmer reflecting telescope operated by the UNC Physics and Astronomy Department. Faint object observing is still possible with narrow wavelength filters to block the city lights of Chapel Hill. The observatory supports research programs in bright star spectroscopy and optical counterparts of Gamma Ray Bursts.
