Prof. Guy Worthey, Washington State University, will present: "Stars and Galaxies"

October 7, 2022 @ 7:30 pm - 9:30 pm MDT

Join the BSU Physics Department for our First Friday Astronomy Event:
Friday, Oct 7th, 7:30pm in Multi-Purpose Classroom Building, Room 101
and Stargazing at 8:30pm in the Sci/Ed Building


Prof. Guy Worthey, Washington State University
will present: Light Detection: Solving the Mystery of Galaxy Formation

Mostly, what the universe sends to the astronomers is light. We spread out the light into its rainbow, or spectrum, and deduce all we can about my favorite class of celestial objects: galaxies. How did these island universes assemble? When? How and where did heavy elements arise? In this talk, Prof. Guy Worthey will review this ongoing detective story and point out a promising new technique for measuring galaxy ages.

The event is free and open to the public.

For those that cannot attend in person, the lecture will be live-streamed on Youtube at Those attending the live-stream are welcome and encouraged to ask questions via chat.

After the lecture we will stargaze in Boise State’s observatory, weather permitting. An indoor planetarium may be set up in case stargazing is not an option.
