February 2, 2021 7:00pm Presentation to WVAC
Presenter: Will Oldroyd
Will is a graduate student at NAU studying Astronomy and Planetary Science. He grew up in Provo, Utah and graduated from Brigham Young University in Physics and Astronomy with minors in Math, Geology, and Spanish. Will’s main research focuses on searching for a mysterious undiscovered giant planet—called Planet X—hidden in the distant outer solar system. Some of the most exciting parts of this research are using supercomputers to visualize how the planets are connected through gravity and using some of the biggest telescopes on Earth (or off of it) to discover new worlds. When he’s finished with school, Will plans on becoming a professor so he can continue studying the universe and share new discoveries with others. In his spare time, Will enjoys hiking and playing board games with his wife and son.

A live Q&A after the 45 minute presentation.
Topic: “You can almost touch the stars”
Even if you wanted to touch a star, they’re all impossibly distant. Despite these great distances, astronomers have learned an enormous amount about stars. How? The most common method to study the stars is called spectroscopy, which is the science of analyzing the colorful rainbow spectrum produced by a prism-like device.
Until recently, spectroscopy was too expensive and too complicated for all but a handful of amateurs. Today, though, new tools make spectroscopy accessible to almost all of us. You no longer need a PhD, dark skies, long exposures, enormous aperture … or a big budget! With your current telescope and FITS camera (or a simple web cam or even a DSLR without a telescope) you can now easily study the stars yourself. Wouldn’t you like to detect the atmosphere on Neptune or the red shift of a quasar right from your own backyard?!
This talk, with lots of interesting examples, will show you what it’s all about and help you understand how spectroscopy is used in research. Even if you are an armchair astronomer, understanding this field will enhance your understanding of the things your read and the night sky.
Speaker Bio: Tom Field is has been a Contributing Editor at Sky & Telescope Magazine for the past 7 years. He is the author of the RSpec software (www.rspec-astro.com) which received the S&T “Hot Product” award in 2011.
Tom is a popular speaker who has spoken to hundreds of clubs via the web at many conferences, including NEAF, the NEAF Imaging Conference, PATS,
the Winter Star Party, the Advanced Imaging Conference, SCAE, and others. His enthusiastic style is lively and engaging. He promises to open the door
for you to this fascinating field!
September 1st, 2020 – Program – Mr. James Renn will make our September presentation entitled “The Vatican Observatory and the Big Bang”.
Mr Renn is a member of the Vatican Observatory Foundation Board of Directors, and is also on staff at the Walker Star Barn Planetarium in Cave Creek. He gives presentations on astronomical topics for both venues.
The presentation begins with a short history of the legacy of the Vatican Observatory, which dates to 1582. It identifys notable members connected to the Observatory, beginning with Christopher Clavius and the 1582 calendar reform, The talk refers to the trial of Galileo as an example of conflict between faith and science, and mentions Angelo Secchi, a founding father of astrophysics. The lecture then discusses Fr. George LeMaitre, who used Einsteins equations to propose a theory of the origin of the Universe we now call “The Big Bang”. This is followed by a short overview of the present state of the Universe and how how the name “Big Bang” was coined by Professor Fred Hoyle in 1949. Finally, the presenter discusses philosophical concepts that personal at the Vatican encounter when they discuss the evolution of the Universe.

NASA’s New Horizons spacecraft flew through the Pluto system in July 2015, collecting a treasure trove of color and panchromatic images, infrared and ultraviolet spectra, and measurements of the local particle environment. Data from the encounter are still being transmitted back to Earth. The downlink will continue until well into 2016, but scientists have been amazed by the data already received. Pluto is far from a dead world. Its volatile ices interact with the atmosphere on seasonal timescales, creating a fascinating and mysterious diversity of landforms. Likewise, Charon is revealed to have far more complicated geology than the inert, cratered sphere some had expected. Even the small moons have interesting stories to tell.

She currently enjoys observing the often clear Southwestern skies while pondering perplexing planetary puzzles.
Title: Exoplanets Abstract: Join University of Arizona Planetary Science PhD candidate Sarah Morrison as she describes her work studying exoplanets. Summary: Within the last 10 years, we now have much more context for our Solar System with the discovery and characterization of thousands of exoplanet systems. To date, however, most of these systems provide insight mainly for the inner planets since they sample planets that orbit close to their host stars. I will discuss cutting-edge efforts to start looking for outer exoplanets using direct imaging campaigns, as well as through indirect evidence in debris disks and current transit/radial velocity surveys and what these findings mean for our understanding of our own Solar System.
(2014-11-25) “A Smashed Up Universe” Speaker – Dr. Paul Knauth of ASU
Title: A Smashed-up Universe – Abstract: The actual history of nature has clearly been astoundingly chaotic. Collisions at all scales are the dominant process shaping what we see. Examples abound and include why no two galaxies look exactly alike, why the solar system looks the way it does, why Mars is fooling us into thinking it had a warm, wet early history, why we are never going permanently into space, and possibly why we are here instead of dinosaurs. Search for the orderly progression of history if you like, but what we see is a smashed-up universe. Come to Dr. Knauth’s presentation and after reviewing it all, you may want to drive more carefully on the way home.
(2014-10-28) “A New World of Possibilities” Speaker – Jim Ray
Richard and Jim Ray are the first astronomers to ever obtain speckle interferometry images of binary stars using a heliostat (solar) telescope. They will explain what they did and how they did it, as well as the science behind speckle interferometry, e.g., how speckle interferometry lets a telescope easily observe at its resolution limit (not the seeing limit imposed by bad air).
(2014-09-30) “The Clark Telescope Renovation Project” Speaker – Kevin Schindler
