NSA member and regular presenter Mark Christensen enlightens us with "The Jantar Mantar: The Biggest Calculating Instrument in the World". The Jantar Mantar is a World Heritage site in Jaipur, India, consisting of 19 different sundials. Its builder, Rajput King Jai Singh, was an astrologer in the 1700s and observed that astronomical positions in the tables then in use did not correspond to reality. So he directed the construction over almost 40 years of a series of more accurate instruments. Recent photographs of the restored site will be exhibited, along with examples of the types of measurements made and details about its history.
This meeting of the Northwest Suburban Astronomers ( NSA ) will be devoted to our annual swap meet, when members bring in equipment to trade, give away, or sell. Entire telescopes, optical tube assemblies, mounts, eyepieces and various other astronomy-related gizmos as well as books and star charts are often offered. Just looking over the items can be very entertaining even if you have no intention of acquiring any new equipment. During the meeting the NSA will also elect new officers for the coming years.
This evening's program will be “The Astronomical Year in Pictures” (aka Brag Night), the annual roundup of pictures and video recordings of astronomical objects and club activities taken by our members during the past year. Those who wish to present their most recent work should contact Tim Klepaczyk (firstname.lastname@example.org).
The Northwest Suburban Astronomers will be hosting a public star party at Marengo Ridge Conservation Area just north of Marengo, Illinois, on October 13th.

Shane Larson of Northwestern University joins us for a presentation on gravitational waves. Up to now, virtually everything we know about the universe has been discovered from the study of photons. However, advanced technology now enables us to study ripples in the fabric of spacetime itself. Over the past two years the first gravitational waves have been detected. They reveal black holes dancing a death spiral billions of light-years distant and neutron stars ripping themselves apart in a titanic burst of light and gravitational energy. Shane's program will explore what gravitational waves are, how we measure them, and what we are learning from them.

Throughout the evening club members and other experts will be giving talks on astronomy in classrooms as well. Please check out the dedicated "Astronomy Day" page available from our homepage menu for exact times and classroom locations for the talks.
Comets have fascinated people since ancient times, when they were often seen as portents of significant events. We know better in our scientific age, but they still engage us. NSA member Todd Augustyniak will give a brief history of comets, discuss their composition, and review their orbital mechanics. He will also provide tips for observation and photography of some of the brighter comets of 2018.
Professor Roger Kolman of Harper College will present current scientific theories about the birth of the sun. A widely-regarded postulate is that a nearby supernova triggered the collapse of the sun's gas cloud, but this conjecture has some discrepancies. Professor Kolman will elaborate and enlighten us on other details of the sun's formation.
Saturn is often the first object that people see through a telescope, and the view is often the event that hooks people on astronomy forever. Why? Because it looks like a real place. And what's more, the entire Saturnian system is astonishing. Michelle Nichols of Adler Planetarium provides a presentation that highlights the astounding discoveries by the Cassini spacecraft, and showcases stunning imagery of Saturn, its rings, and its varied moons.
NSA member Mark Christensen presents a program on the Neutron star Interior Composition ExploRer (NICER) X-ray telescope that was installed on the International Space Station last summer. Its purpose is to provide very high resolution timing data and energy spectra. While we have a broad understanding of the nature of neutron stars, their internal composition remains largely a mystery. NICER’s secondary objective is to examine the use of soft X-ray emissions as timing beacons for GPS-like navigation in deep space.
Join the Northwest Suburban Astronomers at the Arlington Heights Library for their annual Swap Meet.

Joe DalSanto, College of DuPage, will present an introduction to the remarkable theories of relativity and how they have changed our understanding of the universe. The most important theory of physical science is Einstein’s Theory of Relativity, yet it remains mysterious to nonscientists.
The Special Theory describes how perceptions of space and time must be revised at high velocities: motion is always relative, no object can travel faster than light, and time actually slows down. The General Theory describes a new view of gravity as a distortion of spacetime; time runs slowly in gravitational fields and mysterious black holes and gravity waves exist.
