Dr. Darren Williams, 7:30 tonight, October 16th.

                                        How Did the Moon Form?

This talk will be live at the Martz-Kohl Observatory and available online

via Zoom <https://martzobservatory.org/lecture-series-october-2024/> . You

are encouraged to come to the observatory to meet Dr. Williams and join in

our always lively Q&A after his talk. If the weather permits, there will be

public viewing opportunities. Dress for being outside as the telescope domes

are not heated.

How and when did the Moon form? Theories have come and gone. One current

theory is that when the Earth was young - less than one-hundred millions old

- a planet hit the Earth. If true, then the Moon might have formed out of

the collision debris launched into orbit around the devastated Earth.

Another theory is that the Moon was captured by the invisible hand of

gravity without a collision. Are one of these correct? How are we to know?!

In this talk, Dr. Darren Williams, professor of astronomy and astrophysics,

will describe what is known about the Moon and use facts to debate the

merits of old and new ideas for how and when it formed.

Dr. Darren Williams is a Professor of Astronomy and Astrophysics, and

Planetary Science at Penn State Behrend in Erie Pennsylvania. As a teen, Dr.

Williams started his future career endeavors as an astronomy hobbyist here

at the Martz-Kohl Observatory.

In addition to teaching astronomy, he studies the climates, orbits,

observable characteristics, and dynamical evolution of planets and

satellites. He is perhaps best known for his innovative work on the

formation and habitability of exoplanetary moons, as well as the climates of

Earth-like planets with unusual spins and orbital shapes. His present work

is on the final stages of planetary accretion, the formation of the Moon,

and designs for a new miniature space telescope (The "Pale-Blue-Dot"

Telescope) to remotely observe the terrestrial planets at sub-pixel

resolution.
