Discovering galaxies

If you are curious about the universe and galaxies, and always had to urge to learn about the discovery of galaxies, then you’re in luck!


The UH Hilo Department of Physics & Astronomy is hosting a free astronomy public lecture by Prof. Jean-René Roy. A former director at the Gemini Observatory and current faculty member in the Department of physics, engineering physics and optics at Laval University in Québec, Canada, Dr. Roy’s presentation titled, "Discovering Galaxies" is set for Tuesday, October 8, 7:00 pm at the Science and Technology Building (room 108). The public is welcome to attend.

About one hundred years ago, galaxies were discovered. Some say that we then found the universe! This talk is about the discovery of galaxies. The realization that galaxies were other “island universes”, like our own Milky Way, at huge distances was a crowning point that ended centuries of speculation. The discovery of galaxies is a fascinating example of the scientific process and of the history of ideas.

Dr. Roy will describe the sequence of works and events that resulted in bursting the size of the observable universe by a factor of one million billions times about a century ago.


Jean-René Roy received his Ph. D. in astronomy from the University of Western Ontario. Following work at several research institutes and observatories, he held a staff position at the Department of Physics of Laval University in Quebec City and has worked with the Large Facilities Office of the National Science Foundation in Arlington, VA. Recently he worked at the Science Mission Office with the Space Telescope Science Institute in Baltimore, MD.

His research areas include the role of bars in the evolution of spiral galaxies, the formation of massive stars and the dispersal of elements in the interstellar medium. More recently, he has explored the issues and challenges of governance and management of large research infrastructures and facilities. He writes about science issues and the history of ideas and instruments in astronomy.
