They are stars in the later stages of their lives that have blown a shell of material off into space. Some of the objects look like rings, while others are considerably more stretched and distorted. The globular cluster M15 in Pegasus may also be in view. A special treat of recent public nights at Behlen Observatory has been the amateur astronomers from the Lincoln and Omaha astronomy clubs, who bring their telescopes to share astronomical viewing with the public. They will be located outside near the south end of the observatory.
All observatory activities are weather permitting.
Herman Batelaan will discuss how the two new physics theories that emerged in the 20th century, quantum mechanics and general relativity, are providing a major conflict. Quantum mechanics forms the basis of our understanding of atomic processes, such as the creation of light and the formation of molecules, and led to the development of practical devices such as the laser. General relativity forms the basis of our understanding of gravitational processes. Behlen Observatory is located at the University of Nebraska Agricultural Research and Development Center a few miles southeast of Mead, and about 35 miles from either Omaha or Lincoln. H. Turn right on Avenue H and continue east about two miles to Eighth Street.
