High Powered Rocketry | David Mestre, Director, Henry B. duPont III Planetarium at the Discovery Museum

The WAS Winter Solstice Party gets rolling with our friend David Mestre from Bridgeport’s Discovery Museum as he shares his experiences in high powered rocketry.  From build to launch, learn the steps to achieve your Level 1 rocket certification.  David will also discuss projects under the high school rocketry club, which include the Team America Rocket Challenge, building for a Level 2 rocket certification, and integrating electronic payloads for remote telemetry.

David joined the staff of the Discovery Museum in 2003, becoming the Director of the Henry B. duPont III Planetarium. He is also a Manager of STEM Learning Programs. With a background in astronomy and astrophysics from Harvard and the University of Pennsylvania, David brings his passion for all thing space in his work as an educator, stargazer, and scientist.

Stars Around the Milky Way: Cosmic Space Invaders or Victims of Galactic Eviction? | Allyson Sheffield, LaGuardia Community College

The Milky Way is a dynamic galaxy: the outer reaches of the galaxy contains intricate webs of structure in the form of thin streams and diffuse clouds of stars. While some of these structures can be attributed to the Milky Way pulling in smaller satellite galaxies, an alternate scenario is that the structures formed in the Milky Way and were evicted to their current location due to the accretion of a satellite galaxy. In this case, the accretion event caused the Milky Way’s disk to oscillate and ring! I will discuss how the chemical abundances of stars in the Milky Way can serve as a way of unraveling their origin.

Dr. Sheffield received her B.S. in Physics from NYU and her Ph.D. in Astronomy from the University of Virginia in Charlottesville. Prior to joining the faculty at LaGuardia, she served as a Science Fellow at Columbia University. Her research is focused on the formation and structure of our home galaxy, the Milky Way, through the study of stellar populations and chemical tagging. Dr. Sheffield is involved in public astronomy outreach events in Queens and co-leads a Girl Scout troop in Greenpoint, Brooklyn.

Winter Field Day Contest at K1WAS with GBARC & HARC

It’s Winter Field Day in the K1WAS ham shack (the WAS Classroom) again this year with our partners at GBARC & HARC.  We practice emergency communications in a winter environment as it is just as important as the preparations and practice that are done each summer but with some additional unique operational concerns.

There’s always lots of food and a lot of fun and everyone with or without a ham radio license is welcome to attend!

We will operate 630 & 2200 meters bands.

Black Holes and the Galaxies They Grow In – Meg Urry, Department of Physics, Yale

Dr. Urry will cover in her talk:

• How we discovered there is a supermassive black hole at the center of every big galaxy, like our own Milky Way galaxy
• How we use the largest space-based and ground-based telescopes to study the growth of those black holes over the past ~12 billion years of cosmic time
• How black hole growth profoundly affects their host galaxies
• How we harnessed the power of 250,000 citizen scientists to identify the galaxy properties, and how we will transition to Artificial Intelligence for the millions of galaxies soon to be surveyed on a daily basis.

All of which is to try to understand how our present-day Universe came to be.

Meg Urry is an American astrophysicist, who was from 2015–2016 the President of the American Astronomical Society, formerly on the Hubble space telescope faculty and was chair of the Department of Physics at Yale University 2007–2013. She is notable not only for her contributions to astronomy and astrophysics, including work on black holes and multiwavelength surveys but also for her work addressing sexism and gender equity in astronomy, and science and academia more generally.

Dr. Joshua Tan

Life in the Universe: Where Does It Come From? Professor Joshua Tan, City University of New York: LaGuardia Community College

The key ingredients and conditions that allowed for the emergence of life have been identified by biochemists for many decades. What is the astronomical context for this emergence? Where did it come from? In this talk I will discuss the astronomical contexts for the emergence of life and, along the way, look at how seemingly alien and exotic astrophysical events planted the seeds that are necessary for you and I to exist. The implications of this in our search for life outside the Earth will be explored as well.

Prof. Tan is an optical astronomer at City University of New York: LaGuardia Community College and a Research Affiliate of the American Museum of Natural History. He is intensely interested in observing the counterparts to short period binary millisecond pulsars. Aside from that, open problems in binary modeling, neutron star physics, and three-body dynamics occupy most of his research thinkspace. Recently, he became entangled with a project to build a research and teaching telescope at Grand Mesa Observatory outside of Grand Junction, Colorado with remote access to be developed for observing at the astrophysics division of the American Museum of Natural History. He received his PhD in astronomy from Columbia University.

Dr. Sarbani Basu

 

Dr. Sarbani Basu – Chair of the Department of Astronomy, Yale University

Sarbani Basu is a Professor in the Department of Astronomy at Yale University. She is also the current Chair of the Department. Dr. Basu received her training in India, and subsequently worked in the U.K. and Denmark before moving to the US to join the Institute for Advance Study, Princeton, NJ. She has been on the faculty of Yale since 2000.

Dr. Basu specializes in the study of the Sun and other stars using data on stellar oscillations (star quakes). Her past research was devoted to studying the details of the structure and dynamics of the Sun, which allowed her claim, long before the particle physics community, that the solar neutrino problem was a problem with the standard model of particle physics, not that of astrophysics. Her current research focuses on two separate topics: The first is the study of variations in the Sun over time-scales that are of societal relevance. To this end she uses solar oscillation data to examine changes that take place inside the Sun over periods of years and decades. Her second focus is to study stars, in particular exo-planet hosts, to determine their structure, age and formation histories in order to understand those systems as well as to shed light on the past and future of the Sun and the solar system. She has more than 200 peer-reviewed publications.

Dr. Basu was awarded the Vainu Bappu Gold Medal of the Astronomical Society of India in 1996 for her contribution to the study of the structure and dynamics of the Sun. She was elected as a Fellow of the American Association for the Advancement of Science in 2015. She is a member of the Board of Directors of the Association of Universities for Research in Astronomy (AURA), a Consortium of educational and other non-profit institutions that operates major publicly funded astronomical observatories in the US. Basu was awarded the 2018 George Ellery Hale prize by the American Astronomical Society for her work studying solar oscillations.
