Basic Celestial Phenomena

An introduction to astronomy with the unaided-eye

| Begin with the Stars | Constellations Index |

 Walt Whitman

When I heard the learn'd astronomer,
When the proofs, the figures, were ranged in columns before me,
When I was shown the charts and diagrams, to add, divide, and measure them,
When I stirring heard the astronomer where he lectured with much applause in the lecture-room,
How soon unaccountable I became tired and sick,
Till rising and gliding out I wander'd off by myself,
In the mystical moist night-air, and from time to time,
Look'd up in perfect silence at the stars.

  BCP pages provide explanations and learning activities in an accessible format to students, teachers, families, and visitors to planetariums. All together they represent an introductory course in observational astronomy, and are used for that purpose by university students. See a page that needs improvment? Please correct it or write it better, email your changes to me, and I'll upload it!
