June's program is "Painting the Sky: Art of the Cosmos" by Mark Paternostro. Mark is a renowned astronomical artist whose work has been featured in print media and television. His presentation traces his career from fine art school to Astronomy magazine to Adler Planetarium and beyond and includes a detailed visual chronology of the art he created along the way.
July's meeting is the next installment of the regular program of member do-it-yourself projects. If you'd like to participate please contact Tim Klepaczyk (firstname.lastname@example.org). Please give reasonable notice to Tim, who will be organizing the order of presentation. Tim can't promise late contributions can be accommodated.
Kent Nebergall of the Mars Society will discuss human planetary expeditions. After four decades of limited launch capability, the U.S. is at the threshold of having three major systems, with two of them being highly affordable. Are we ready? There are also serious issues that may hamstring the next space technology revolution. How will this new space age compare to our dreams from the late Apollo Era?
The Northwest Suburban Astronomers (NSA), in cooperation with the Dekalb County Forest Preserve District, will be hosting a public star party on Saturday, May 5th, at Afton Forest Preserve, located at 13600 Crego Road, south of DeKalb, Illinois. View and learn about planets, stars and star clusters, galaxies, and nebulae with the help of NSA members and their telescopes. Observing highlights will include Venus, Jupiter and its moons, Globular Cluster M3, various galaxies in Leo and the Virgo Cluster, and many other fascinating celestial objects.
Dress for evening and bring a flashlight covered with red plastic or cellophane (red light preserves everyone’s night vision) as well as insect repellent. Please arrive around 7:45 p.m. (sunset is at 7:53). You are welcome to bring your own telescope or binoculars. In the event of inclement weather the event will be canceled. There is no cost to attend and no registration is required.
Join the Northwest Suburban Astronomers for an afternoon of solar observing from 1 to 4pm at the Cary area Public Library. Enjoy views of our nearest star, including sunspots and solar prominences ( if there are any visible ), through telescopes specially equipped for solar observing. The event will be canceled in case of inclement weather.
NSA's guest speaker will be Professor Kevin Cole of Harper College. Kevin's topic is the Juno mission to Jupiter, which has been in orbit around the planet since July, 2016. He will provide an overview and discuss Juno's primary goal of studying Jupiter’s interior structure and the nature of the planet's core. He will also review the Juno Cam instrument and its connection with NASA’s public outreach program.
The Northwest Suburban Astronomers will be marking Astronomy Day 2018 at Harper College in Building Z on Saturday, April 21st. NSA members who will be on hand discuss all aspects of their hobby and demonstrate the use of telescopes and other astronomy accessories, books, and charts. 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. Members bring in all kinds of astronomy-related equipment, including telescopes, mounts, eyepieces, books, and all kinds of gadgets and what-not for swapping or purchase. Just looking at the items can be entertaining in itself and lead to interesting and informative conversations.
The election of 2018 club officers will also be held at this meeting.
Frances Dellutri, Deputy Education Manager for Enterprise in Space ( EIS), will be speaking about the EIS. This program will launch and return from space an orbiter with 100 student experiments. EIS is the educational arm of the National Space Society and is involved in bringing space science to students of all ages around the globe.
The Northwest Suburban Astronomers return with their high-tech telescopes to offer you views of the planets Neptune and Uranus, as well as numerous deep sky objects such as the Andromeda Galaxy, the Pleiades, and the globular cluster M15. Telescopes will be set up the front parking lot. If the lot is full, please park at Three Oaks School.
Please note, in case of inclement weather, the rain date for this event is 26 October, when the moon will be just short of first quarter, and at its best for dramatic views of lunar mountain ranges, maria, and craters.
This month's meeting is devoted to “the Astronomical Year in Pictures” (aka Brag Night), the annual roundup of pictures of astronomical objects taken by our members during the past year. Members who wish to present their most recent work should contact Tim Klepaczyk (email@example.com). Please give reasonable notice to Tim of your intention to participate.
After the meeting we will adjourn to Rosati’s at 1770 W. Wise Rd in Schaumburg for pizza and discussion.
Join the Northwest Suburban Astronomers (NSA) for an evening of stargazing at Marengo Ridge Conservation Area, located just north of Marengo on Route 23. NSA members and their telescopes will be on hand to show visitors Saturn, Neptune, various stars and star clusters in the Milky Way, and our near neighbor, the Andromeda Galaxy. Feel free to bring your own telescopes or ask club members any questions you have about telescopes and astronomy in general.
Visitors are requested to arrive by 6:45 so as not to have to use headlights when driving into the parking area and blinding other observers. If possible, bring a red flashlight to better maintain your night vision, and don't forget to dress for a late September evening. In the event of inclement weather the event will be cancelled. There is no cost to attend and no registration is necessary.
NSA members will be observing the Great American Eclipse of 21 August from many different locations throughout the U.S. At this evening's meeting, members will recount their experiences in viewing this rare and spectacular phenomenon. Please contact club VP for Programs Tim Klepaczyk with content (pictures and videos) you plan to present.
Note that the meeting will be held at the Schaumburg Library, located at 130 S. Roselle Rd. in Schaumburg. Afterwards club members and guests will adjourn to Rosati's on Wise Rd. for the usual pizza and further discussions.
The Northwest Suburban Astronomers (NSA), in cooperation with the Dekalb County Forest Preserve District, will be hosting a public star party on Saturday, September 2nd, at Afton Woods Forest Preserve, located at 13600 Crego Road, south of Dekalb, Illinois. Come and let NSA astronomers show you the Planets Saturn and Neptune, double stars, galactic as well as globular star clusters, our own galaxy, the Milky Way, and our “neighbor”, the Andromeda Galaxy. Club members will be on hand to answer questions on astronomy and telescopes as well.
Dress for evening and bring a flashlight covered with red plastic or cellophane ( red light helps preserve night vision ) and don’t forget insect repellent. Please arrive by 7:15. ( sunset is at 7:21 ) so that car headlights don’t blind other participants. You are also welcome to bring your own telescope or binoculars. In the event of inclement weather the event will be cancelled. There is no cost to attend and no registration is required.
Join the Northwest Suburban Astronomers and observe our nearest star with special telescopes and filters. See sunspots and solar prominences in remarkable detail! This will be a fun and safe activity for the entire family. After observing the sun, take a hike on your own or join a walk led by Stillman’s naturalist.
If you like, bring a dish and join us for a potluck picnic. Remember to call Stillman at 847-428-OWLS (6957) and let them know if you’re coming. If the weather is iffy, call Stillman for an update before making the trip.
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.
In the run-up to the 21 August total solar eclipse, people are becoming more and more interested in the nearest star, our sun. Why not stop by the Palatine Library and join the Northwest Suburban Astronomers in viewing the sun as you've never seen it before. A variety of telescopes equipped for safe solar observing will be on hand to show you sunspots, solar prominences, and the sun's granular appearance. The event will not be held in case of overcast.
NSA member Eric Coles will be presenting a program on advanced image
processing techniques. He will describe his efforts with tone mapping and
enhanced HRGB imaging of emission nebulae.
Please note that the meeting is being held at the Arlington Heights Library, located at
500 N. Dunton Ave, Arlington Heights. Following the meeting we will be going to Moretti’s Pizza, 1893 Walden Office Square, Schaumburg, IL.
Northwest Suburban Astronomers (NSA) member Jerry Chern and his son, Adam, attended Astrofest in 1999 to help Adam choose an appropriate optical system for his first serious telescope. The Astrofest brought together astronomy enthusiasts and amateur telescope makers from a wide area and facilitated the sharing of information, techniques, and experience. The result of their visit was the acquisition of what turned out to be, with some modifications by Jerry, a very effective and optically excellent 8-inch telescope. At our June meeting, Jerry will present footage from his visit to Astrofest, featuring a wide array of telescopes as well as some faces familiar to the local amateur astronomy community. Additionally, Jerry will show some total eclipse videos as we continue to prepare for the August 21st solar eclipse.
Join the Northwest Suburban Astronomers (NSA) for a public star party at Heritage Community Park, 32250 Darrell Road, in Lakemoor, Illinois, on May 25, from 8 to 10 pm. NSA members will be on site with telescopes to share their love of astronomy with the public. We will be observing the Planet Jupiter, with its moons, and cloud belts, galaxies in Virgo and Leo, the spectacular globular star clusters M3 and M13, and other celestial objects.
Please try to arrive by 7:45 pm. Some of the best views of the planets, especially of Jupiter, are obtained in twilight, before the planet's glare becomes overpowering. Also remember to bring mosquito repellent and dress appropriately. In case of rain the event will not be held.
On Friday, May 12, Dean Ketelson of the Richard F. Caris Mirror Lab of the University of Arizona in Tucson will speak on the Lab's primary project, the Giant Magellan Telescope. The telescope, scheduled for commissioning in 2022, will consist of 7 mirrors, each 8.4 meters in diameter. It will be located in Chile, at one of the highest and driest locations in the world. The Giant Magellan Telescope will seek answers to questions such as how the present universe took shape after the Big Bang and what is its ultimate fate, how were the first galaxies formed, what is the nature of dark energy and dark matter, and is there life on other worlds.
Celebrate Astronomy Day 2017 with the Northwest Suburban Astronomers and the Harper College Department of Physical Sciences. Club members will be giving tips on getting started in the hobby, demonstrating telescopes and associated equipment, and discussing the latest discoveries in the cosmos. Special attention will be devoted to the upcoming August 21st total eclipse of the sun, which will be visible from southern Illinois and neighboring Missouri. If skies are clear. telescopes will be trained on Jupiter and guests will view its moons and cloud bands. The event begins at 5:30 pm at Harper College, Building Z, 1200 West Algonquin Road, in Palatine. Use the Algonquin Rd entrance.
Kevin Cole, of Harper College, will present information about the European Space Agency's Rosetta Mission to Comet 67P/Churyumov-Gerasimenko, , including the orbiter and lander. The Rosetta space probe was launched in March, 2004, and arrived at its target ten years later, in August, 2014. Rosetta's lander, named Philae, landed on the comet's surface, but was unable to report the expected volume of data due to its being in shadow and thus unable to maintain battery power in its solar cells. The mission provided information, among other things, on the comet's apparent lack of a magnetic field and the difference between water vapor surrounding the comet and that on Earth. The Rosetta orbiter continued to send data until it was deliberately brought down on to Comet 67P on 30 September, 2016.
This evening club member Mark Christensen will discuss theories concerning the formation of the Moon, its post-formation history, and the future of the Earth-Moon system. This is a tale more complex and exciting than the casual reader might think. The Earth-Moon system is unique in our solar system in that it consists of a rocky planet and a single satellite that is 1/4 the diameter of its primary. The leading theory, based on, among other things, the chemistry of rocks on both the Earth and the Moon, is that the Moon formed when the Earth was struck by another planetary body. However, there is as yet no direct evidence that definitively proves this theory, with which there are dynamical problems as well. After this evening you may never look at the Moon again in the same way!
Come join the Northwest Suburban Astronomers as club members present their own do-it-yourself astronomy-related projects. These range from the simplest to the most complex, from simple, helpful gadgets to quite sophisticated research. This promises to be an interesting, entertaining, and, if past experience is any guide, very enlightening evening.
Please join Jim Kovac, NSA member and NASA Solar System Ambassador, for Mysteries of the Cosmos – The Possibility of Life on the Moons of Jupiter and Saturn. We are either alone in the Universe or we are not; either possibility is overwhelming! Join the exploration of the fundamental question about the pervasiveness of life -- is it common or rare? The focus of this presentation will be the unique environments of the planet-sized moons of the Gas Giants and their potential as abodes for life.
Proto-Solar System Formation
Yoram Lithwick, Associate Professor, Dept of Physics and Astronomy at Northwestern University
Professor Lithwick will speak on the topic of Proto-Solar System Formation, an area of research and simulation he has been involved with for the past several years at Northwestern University. Professor Lithwick works on a variety of topics in theoretical and computational astrophysics. He is especially interested in planet formation, including both the early and late stages of this process. For the early stages, he is interested in the dynamics of the gas disk that surrounds a newlyformed star, and for the late stages he is interested in how planetesimals accumulate into planets, and what sets the architecture of the resulting planetary system. Other topics he works on include the formation of cosmological dark matter halos, magnetohydrodynamic turbulence (MHD) turbulence, and gamma-ray bursts.
