July Membership Meeting: LIGO Part 2

Madeline Wade, Ph.D.

The July 2019 membership meeting of the Cuyahoga Astronomical Association (CAA) will take place Monday, July 8, beginning at 7:30 PM.

Featured speaker for the evening will be Dr. Madeline Wade, Assistant Professor of Physics, Kenyon College. Dr. Wade writes: “The Advanced Laser Interferometer Gravitational-wave Observatory (aLIGO) has been making ground-breaking discoveries since the moment it turned on in 2015. The LIGO and Virgo Scientific Collaborations have published results for 11 total gravitational wave detections. We have detected gravitational waves from ten merging black hole systems and one merging neutron star system. In this talk, I will give an overview of gravitational-wave physics, the LIGO detectors, and give some highlights of the current discoveries. I will also discuss some of the current and ongoing research I am involved in, including calibration of the LIGO instruments and applications of machine learning algorithms to improve the quality of LIGO data.”

The CAA’s monthly meetings are held on the second Monday of every month (except December) at 7:30 PM at the Rocky River Nature Center; 24000 Valley Parkway; North Olmsted, Ohio, in the Cleveland Metroparks. Meeting programs are open to the public. Following the presentation and a brief social break, the club will conduct its membership business meeting.

The Cuyahoga Astronomical Association (CAA) was well-represented this year at the annual Lakewood Solstice Celebration held on the shores of Lake Erie. CAA members brought 11 telescopes to help support a successful annual Summer Solstice program at Lakewood City Park.

Lakewood Park features an amphitheater-like Solstice Steps facility where visitors are able to view the Great Lake. The evening event draws thousands and boasts food, music, activities and, thanks to the CAA, safe solar viewing and after-sunset astronomy.

Attendees enjoyed clear, sunny skies for most of the day right up until just before sunset. Safe solar viewing was offered through a variety of telescopes and filters though, because Sun was at Solar Minimum, there wasn’t much to see on old Sol’s face.

After sunset, however, Jupiter rose above the trees in the east, providing an opportunity to show visitors Jupiter and a few of his Galilean Moons.

CAA member Jay Reynolds again organized and coordinated the Solstice astronomy program with the city of Lakewood. Reynolds passed along compliments from the city for the timely and organized manner in which members arrived, unloaded, and kept the flow going as members set up their telescope systems.

Lakewood city officials and staff welcomed and supported CAA as part of their annual event. Lakewood Mayor Mike Summers and his wife, expressed how much they enjoy coming to the event and this (telescopes) was their favorite part!

The Lakewood Solstice Celebration is one of several public events in which CAA members provide astronomy outreach programming. “It’s what we do.”

Come see deep-sky objects, planets, and the Moon up close using the Cuyahoga Astronomical Association’s (CAA) telescopes, from 9:00 to 11:00 PM, Saturday, June 8.

The CAA Observatory will be open for public viewing, and members will be available to answer your questions. Activities and/or displays will be set up inside the barn for further interest on cloudy nights. Given clear enough skies, visitors may view Earth’s Moon, planet Jupiter, and star clusters through a variety of member-owned telescopes.

This is an outdoor program so attendees should dress appropriately for conditions; use of insect repellent is also recommended.

April 8 Membership Meeting: The Great Melbourne Telescope rises again

The April 2019 Membership Meeting of the Cuyahoga Astronomical Association will take place on Monday, April 8 beginning at 7:30 PM. The evening’s program, “Rising From the Ashes: Restoration of the Great Melbourne Telescope,” will be presented by Trudy E. Bell, M.A. Ms. Bell is a Sky & Telescope Contributing Editor, 2006 recipient of the American Astronomical Society’s David N. Schramm Award, and board member of the Antique Telescope Society.

When completed in 1869, the Great Melbourne Telescope was the world’s largest equatorial reflector. Today, 150 years later — after a bushfire that devastated the Mount Stromlo Observatory — Australian opticians and machinists are restoring the GMT to become one of the world’s largest telescopes for public outreach! Ms. Bell’s latest article about the restoration appears in the October 2018 issue of Sky and Telescope magazine.

The March 2019 Membership Meeting of the Cuyahoga Astronomical Association will take place on Monday, March 11 beginning at 7:30 PM. The evening’s program, “Gravitational Waves from Colliding Black Holes,” will be presented by Rob Owen, Associate Professor of Physics and Astronomy, at Oberlin College.

Dr. Owen is a member of the Simulating Extreme Spacetimes collaboration (www.black-holes.org), which carries out supercomputer simulations of colliding black holes and neutron stars. Such simulations are essential for relating gravitational wave signals (such as those measured by the revolutionary LIGO observatory) to the astrophysical sources that produce them. In this talk he will describe the work and the often misunderstood physics of black holes and how they relate to the structure of space and time!

The CAA’s monthly meetings are held on the second Monday of every month (except December) at 7:30 PM at the Rocky River Nature Center; 24000 Valley Parkway; North Olmsted, Ohio, in the Cleveland Metroparks. Meeting programs are open to the public. Following the presentation and a brief social break, the club will conduct its membership business meeting.

The Monday, February 11 meeting of the Cuyahoga Astronomical Association, will feature John Ruhl, Ph.D., Professor of Physics and Cosmology at Case Western Reserve University, as guest speaker. In his talk, “Looking for the Dark,” Dr.Ruhl will describe the latest findings from two new and unique projects designed to utilize gravity waves and the Cosmic Microwave Background (CMB) radiation to search for the mysterious Dark Energy that is causing our universe to expand!

November 12: Final membership meeting of 2018

Artist's Concept: Kepler-186f was the first rocky planet to be found within the habitable zone -- the region around the host star where the temperature is right for liquid water. This planet is also very close in size to Earth. Even though we may not find out what's going on at the surface of this planet anytime soon, it's a strong reminder of why new technologies are being developed that will enable scientists to get a closer look at distant worlds.

The Monday, November 12 meeting of the Cuyahoga Astronomical Association (CAA), at Rocky River Nature Center, will be the last for the year and will feature the election of officers and at-large board members for the next two-year term. Annual dues will also be due at that time.

The evening’s program, which is open to the public, is titled, “Discovering New Worlds”
presented by CAA member Lydia Bindal. Ms. Bindal will take us on a metaphorical expedition to explore exoplanets: planets which aren’t a part of our solar system! How do we detect them? What have we found so far? What are their properties? What can they tell us about our own solar system? And could they possess life?

The CAA’s monthly meetings are held on the second Monday of every month (except December) at 7:30 PM at the Rocky River Nature Center; 24000 Valley Parkway; North Olmsted, Ohio, in the Cleveland Metroparks.

Following the presentation and a brief social break, the club will conduct its membership business meeting.
