Title: “Navajo Astronomy as Learned at Little Singer Community School”

The first snowfall has happened on the peaks and is a demarcation on the Navajo calendar, indicating it is time to share stories about the night skies.

Asterisms such as the Female Revolving One (Cassiopeia), the Male Revolving One (Ursa Major), and the Central Fire (Polaris) provide the hogan in the night sky. When studying the night sky, we establish our orientation with the hogan and search for the other Navajo asterisms.

The book Sharing the Skies, Navajo Astronomy by Dr. Nancy Maryboy and Dr. David Begay, accompanying resources from the Indigenous Educational Institute, and teachings from home, provide our students with cultural content when interpreting the night skies.

Presenter: Dr. Larry Wasserman

Title: “Things that go bump in the night - Eclipses, Transits, Conjunctions, and Occultations”

Occasionally two or more objects appear close to each other in the sky. Dr. Wasserman will discuss each of these events, what we can learn from these various events, with emphasis on those which are scientifically important.

Bio: Dr. Wasserman is the longest-tenured astronomer at Lowell Observatory, having begun working here in September 1974. As a graduate student at Cornell he worked with Dr. Carl Sagan, who was his thesis advisor. In 1974, he came to Lowell Observatory where over the years he has been involved in observing and predicting occultations in our Solar System. He has also studied double stars and Kuiper Belt Objects.

Title: “An Overview of the Seestar 50 Digital Telescope”

The Seestar 50 is a new kind of telescope that can be controlled with a mobile device. Since it blends many different features and capabilities, it has become very popular, since it allows even novices to take interesting astronomical images easily. In this presentation, Padraig will provide examples and critiques of images taken with one and address the device's pros and cons.

Speaker Bio: Padraig has been involved in Astronomy for most of his life; He holds a Ph.D. in Astronomy from the University of Texas (Austin), and has taught Physics and Astronomy at various colleges. He also has spent considerable time in I.T. administration, at Oregon State University and Lowell Observatory. His main interests are in various types of celestial imaging.

Title: “Planet Formation in Young Binary Star Systems”

Description: Most stars are located in binary or multiple groups. Astronomers have discovered some transiting planets around both stars in close binary star systems and around individual stars in wider binary systems but it is unclear how robust the planet formation process is in these complex environments. She will discuss her team’s work to characterize the planet-forming circumstellar disks and the stars themselves in young binary systems to better understand the frequency and character of planets in dynamically challenging locations.

Bio: Lisa Prato grew up in the Boston area and attended the University of Massachusetts, Amherst, where she completed undergraduate degrees in Astronomy and in English and discovered the world of scientific research. After another year at UMass as a non-degree graduate student, Prato moved to Colombia, South America, and worked for 3 years as a professor in the Department of Physics at the Universidad Industrial de Santander in the city of Bucaramanga, teaching classes in astronomy and astrophysics and working toward a masters degree in Physics. Prato returned to the US to complete a PhD in Astronomy at the State University of New York at Stony Brook, followed by two postdoctoral positions at UCLA, one with the Nobel Laureate Dr. Andrea Ghez and one with Dr. Ian McLean. Prato is a Tenured Astronomer on the science faculty at Lowell Observatory and an Adjunct Professor at Northern Arizona University; she works with postdocs, undergraduates, interns, and gradate students on young binary stars and planet formation.

Title: “ The Moon as it Never Was”

In 1874, James Nasmyth and James Carpenter published a remarkable book, The Moon: Considered as a Planet, a World and a Satellite, which quickly became one of the most influential works on the lunar surface ever written. In addition to containing the most spectacular and detailed images of Moon at the time, it was also the first serious scientific treatise dealing with the origin, formation and geology of our Moon during the Victorian era. How well has it stood the test of time? Better than might be expected.
