Sturm Memorial Lecture

In memory of Kenneth E. Sturm, a Wesleyan alumnus, this annual event is held in the spring and is open to the public. It features a presentation from an astronomer that is outstanding in their field and able to communicate the excitement of science to a lay audience. The event is free and open to anyone.

The 2023 Sturm Memorial Lecture

How the Earth came to be: clues from the Asteroid Belt

Speaker: Dr. William Herbst, Wesleyan

Tons of rocky debris from the asteroid belt hits the Earth every day. Most of it burns up in the atmosphere, producing meteors, while some rocks make it to the ground as meteorites. Most are relics of an earlier time, about 4.6 billion years ago, before the Earth had formed; they contain coded clues to the birth of all the planets. Unfortunately, decoding that information has proven difficult! Now, we are getting direct samples of nearby asteroids to help. In this talk we will explore how recent studies of meteorites and asteroids are helping us reach a better understanding of our past and the nature of those rocks from space that pummel us daily.

Date: Tuesday, April 4, 2023, 7:30PM

Where: Ring Family Performing Arts Hall, Wesleyan University

Reception and telescope viewing at the Van Vleck Observatory to follow the lecture.

The Sturm Memorial Lecture is sponsored by the Astronomy Department, the Allbritton Center for the Study of Public Life, and NASA Connecticut Space Grant Consortium.
