The Distance Modulus Method
One of the fundamental requirements for astronomy to work as a science is the need to accurately measure the distances to objects. Astronomers have developed a series of methods for measuring stellar and cosmic distances, which fit together and inform … Continue reading
A Constellation in a Box
Several weeks ago I wrote up a lesson plan as part of a contest sponsored by ORISE, the Oak Ridge Institute for Science and Education. Winners of the contest would receive an all-expenses paid trip to the National Science Teachers … Continue reading
