Great Lakes Association of Astronomy Clubs

Share

GLAAC was founded to make it easier for amateur astronomy clubs to collaborate on big events.

The Great Lakes Association of Astronomy Clubs is an organization dedicated to communicating astronomy with the public. It was formed with the purpose of making it easier for our clubs to work together and do more. Our biggest collaborative event is Astronomy at the Beach, held every September in SE Michigan.

Astronomy Movie Matinee! James Webb Space Telescope on IMAX at the AMC Forum 30 in Sterling Heights - Sat. Feb. 21st 1:00 pm.

Several members of the Warren Astronomical Society will be attending this movie, and there's a Dunkin' Donuts/Baskin Robbins right nearby for gastronomy after astronomy!

Deep Sky brings the awe-inspiring images captured by NASA's Webb Telescope to IMAX — taking audiences on a journey to the beginning of time and space, to never-before-seen cosmic landscapes, and to recently discovered exoplanets, planets around other stars.

Directed by Oscar-nominated filmmaker Nathaniel Kahn and narrated by Oscar-nominated actress Michelle Williams, Deep Sky follows the high-stakes global mission to build JWST and to launch it into orbit one-million miles from Earth, in an attempt to answer questions that have haunted us since the beginning of time: Where did we come from? How did the universe begin? Are we alone? Thirteen billion years in the making,

Deep Sky reveals the universe as we have never seen it before; immersing audiences in the stunning pictures beamed back to earth by NASA’s new telescope — and capturing their vast beauty at a scale that can only be experienced on the giant IMAX screen.

Explanation: This infrared view of Jupiter by Webb is illuminating. High-resolution infrared images of Jupiter from the James Webb Space Telescope (Webb) reveal, for example, differences between high-floating bright clouds -- including the Great Red Spot -- and low-lying dark clouds. Also clearly visible in the featured Webb image are Jupiter's dust ring, bright auroras at the poles, and Jupiter's moons Amalthea and Adrastea. The footprint of large volcanic moon Io's magnetic funneling of charged particles onto Jupiter is also visible in the southern aurora. Some objects are so bright that light noticeably diffracts around Webb's optics creating streaks. Webb, which orbits the Sun near the Earth, has a mirror over six meters across making it the largest astronomical telescope ever launched -- with over six times more light-collecting area than Hubble.

Rings around infant stars

Not all rings are forged in fantasy, my precious!

For astronomers, they are found in space and are debris discs. These are the leftovers of planet formation around stars and studying them is key to understanding the birth of planetary systems.

You can admire 24 of them in these images by ALMA Observatory. The orange ones show the distribution of dust, and the blue ones of gas.

The origin of gas in debris discs is debated, and the disc in the two images at the top-right is very interesting in this regard. Here's why: https://www.eso.org/public/images/potw2603a/

Images from our annual Astronomy at the Beach event. We had the pleasure of hosting 3000 members of the public over two nights.

A very big thank you to our keynote speaker Br. Guy J. Consolmagno, S.J for two entertaining and compelling talks about Saturn.

Another big thank you to Sean Pickard who gave talks on electronic telescopes.

To all our member clubs, this event happens because of your passion for Astronomy and your love for outreach and sharing your knowledge and experiences with the members of the public.

And finally, a special thank you to the meme era of the public that attend our annual event. Our event started 29 years ago and continues to grow in popularity year after year. We love to see returning participants just as much as first timers. We hope you all had a wonderful event and look forward to seeing you all back in in 2026 for our 40th year of Astronomy at the Beach.

On behalf of the board and planner committee of the Great Lakes Association of Astronomy Clubs, we thank each and every one of you for making the event a success.

Larry Lebofsky's meteorite kits with a magnet were a HUGE hit!
