In this monthly series, scientists present different scientific topics to the general public in a laid back fashion.
The February event:
Extinct Radioactive Atoms and the Early Solar System
Presented by Matt Bowers, University of Notre Dame
(full abstract below)
Exciting science, art and socializing!
Delicious food to buy from the Vegan Food Truck!
At Layne Jackson's Art Shop
The gallery is just south of the Division blue line stop.
Also accessible by the Ashland (#9) and Division (#70) buses.
Some street parking is available.
The presentation will be 8-9 pm.
We hope you will join us!
You are also invited to join the Art of Science facebook group and be invited to future events.
Over four and a half billion years ago, a large cloud of interstellar gas and dust collapsed on itself to form the Solar System. A few different radioactive atoms were alive during the formation and early stages of the history of the Solar System, and decayed since. Hence they are called extinct radioactive atoms. Evidence for the past existence of these extinct radioactive atoms is obtained mainly from extraterrestrial rocks that fall to Earth and are called meteorites.
In this presentation, Matt Bowers will explain how studying extinct radioactive atoms reveals some of the physical and chemical conditions during the formation of the Solar System and its early history. He will also show how extinct radioactive atoms are used to get the ages of some processes in the early Solar System.
