Have you ever heard the phrase that humans are literally made of star dust? At the Vanderbilt Dyer Observatory this Friday, Sept. 2, stargazers can come learn just how that is so during a lecture on cosmic history by Dr. Jonathan Bird.

His lecture titled “Where Have You Been? A Guided Tour of Your Cosmic Location History” will discuss scientific results covering a variety of fields.

Bird will go over cosmology and the shape of the universe, gravity and general relativity, the structure of the nucleus and atomic physics, nuclear reactions in stars, and much, much more. He will also talk about how many of the atoms that make up the human body were created by stars billions of years ago, explaining how humans are made of star dust.

The lecture will end with a question and answer session, and there will be a viewing at the Seyfert Telescope afterwards, weather permitting.

Bird is the Stevenson Fellow for Astrophysics at Vanderbilt University, and is interested in how spiral galaxies like our own Milky Way form. He considers himself an observationally oriented theorist, and his research uses both state of the art computer simulations and observations to investigate the mechanisms that govern the formation of galaxies.

He graduated with a B.S. with honors in physics from the California Institute of Technology, and received his master’s and PhD in astronomy from Ohio State University.

His lecture will take place on Friday, Sept. 2 from 7 p.m. to 9 p.m. at the Vanderbilt University Dyer Observatory, located at 1000 Oman Drive in Brentwood. The lecture costs $5 and tickets can be purchased here.
