Join us for the 2022-23 AAA Lecture Series
Our guest speaker for November 8 is Dr. Brian Welch, of Johns Hopkins University. The topic will be: The Light of Earendel: Studying the First Stars with HST and JWST.
The Amateur Astronomers Association Lecture Series is on the second Tuesday of the month, from October–May (unless indicated), beginning at 7:00 PM Eastern time.
Lectures are free and open to the public, but registration via Zoom is required.
Brian Welch’s research focuses on studying small physical scales in distant galaxies, down to the level of individual stars. They examine galaxies that have been magnified by gravitational lensing, which enables us to see smaller features than would be visible in unlensed galaxies. In some cases, this includes magnifying individual stars by such large amounts that the can be distinguished from their host galaxies at great distances.
