Trying to understand our origins is part of far reaching research projects in astronomy. These include understanding and modelling our Universe which contains a plethora of galaxies where our Milky Way is only one. The general picture of a cosmos filled with many galaxies is now common knowledge.
However, as astronomy became astrophysics and both spectroscopy and larger telescopes became essential equipment of astronomical research a problem arose. Nebulous objects representing spiral features were well known but could not be convincingly explained as being within our galaxy given certain newly discovered properties. Dr R Turner (NTU) will illustrate the dilemma and tense discussions resulting from the debate if these nebula could be objects beyond our galaxy in his talk Outside the Galaxy - A Brief History of Extragalactic Astronomy. This talk will be followed by a brief introduction on what is visible in this month's sky.
