Open Dome Event - Outside the Galaxy - A Brief History of Extragalactic Astronomy
We are quite familiar with the Universe containing thousands and millions of galaxies. But astronomy only became extragalactic at the beginning of last century. Learn more about how we discovered what was beyond our home galaxy the Milky Way and the early history of extragalactic astronomy in Dr R Turner's (NTU) talk Outside the Galaxy.
- From: Thursday 29 January 2015, 8 pm
- To: Thursday 29 January 2015, 10 pm
- Location: CELS, Nottingham Trent University, Clifton Campus, Clifton Lane, Nottingham, NG11 8NS
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.

The event will start at 8 pm with the talk Outside the Galaxy in CELS. Refreshments will be offered from 7.45 pm in the CELS foyer. Afterwards, visitors will get a tour of the NTU observatory and the chance to see interesting objects in the winter sky with the observatory's telescopes, small telescopes, and binoculars if the weather allows it.
If the weather is not good, a small planetarium session will be offered in the observatory pointing out objects of interest.
