“V1 – The star that changed the Universe” – no date yet

Lecture cancelled due to coronavirus. Was scheduled for March 2020 Coming soon, we hope – prominent amateur astronomer Tony O’Hanlon will tell how observation of single star was to change how we saw the Universe, and relegated our Milky Way to just one of billions of objects. This lecture was originally scheduled for 9th March 2020. Meeting cancelled due to coronavirus situation in Cork while we await HSE guidance.

As recent as the early 1920’s, we believed the entire Universe consisted of what we called the Milky Way.  Some astronomers of the day believed it was much larger, but how to prove it was a huge mathematical and observational problem and much debate ensued.  Edwin Hubble, after whom the Hubble Space Telescope was named, then made a key discovery from his observations of a single star. It changed how we saw the Universe. Our understanding that our Milky Way is just one of billions of objects can be traced back to Hubble’s discovery.  In this talk, Tony will tell its story.

Tony is a member and co-founder of Limerick Astronomy Club, and a former V.P. of the Irish Astronomical Association.  His passions lie in deep sky objects and providing astronomy outreach.
