Reminder: TAAS Monthly meeting. When: Thursday, April 17, 2025 Organizer: Mark Strollo mark@... View Event Description:

As promised the event description to be posted to the general public is as follows. I plan to be there an hour in advance to set up for each event. I am planning on getting traffic cones from the town of Madison to block our observing area and we've had a club member volunteer for parking control. Please note the map link at the very bottom which will show the observing area /public and astronomer parking/ etc... The Shoreline Astronomical Society (SAS), a local 501(c)(3), has organized quarterly star parties at Salt Meadow Park (1362 Boston Post Road Madison, CT 06443), which are free and open to the public. People of all ages and backgrounds, including children, are welcome. Please join us for the opportunity to look through different types of telescopes, get hands-on experience using a club telescope, and discuss observing, telescopes, and all things astronomical. Some helpful notes to get the most from our Star Parties: Please join us early in the event if possible to avoid light from car headlights If you bring a flashlight, please bring a red light to preserve visual dark adaption Please leave your canine companions at home for this event; even well-behaved pups on a leash can sometimes get tangled in observing equipment/tripods/legs in the dark Bring your binoculars or telescope (we can help you figure out how to use your equipment if you need help) If it is cloudy or otherwise unfavorable for observing please check our social media accounts or our website (https://shorelineastronomicalsociety.blogspot.com/p/salt-meadow-public-star-parties-2025.html) for a weather cancellation up to 2 hours before the event. If the weather is ideal, please dress warmly, bring effective bug spray, and a warm drink Dates and Times as Follows Please RSVP via shorelineastronomicalsociety@... May 17th - 8:30-10:30 PM July 26th - 9:00-11:00 PM October 4th - 8:00 - 10:00 PM Map with Parking Area and Telescope Areas Delineated -- Jeff Dunn https://shorelineastronomicalsociety.blogspot.com/

Hi Folks, I am so sorry that I didn't send this invitation to you earlier. I hope a few of you can attend, but I understand that this talk announcement was sent very late. Anyway, here is the information. Talk title: “Monsters in the dark: searching for the origins of the most massive galaxies in our universe” Speaker: Dr. John Weaver, graduate of the Williams School 2013. Date: Wednesday, April 16. Refreshments: 4:15 - 4:30 p.m. Talk Time: 4:30p.m. Talk location: Fanning 111 Talk Description: Despite a century of observations, the origins of the most massive galaxies in the nearby universe remain elusive. Although much progress has been made, the details of their formation have been lost to time. Thankfully, telescopes are time machines, which means we can catch their progenitors in action in the distant, high-redshift universe. However, these galaxies are also extremely rare, forming in only the greatest collections of dark matter and cold gas. While this makes them ideal cosmological probes, observations capture only snapshots of different galaxies at different redshifts and cosmic epochs. Accurately piecing together this grand story therefore requires large statistical samples from the most sensitive infrared telescopes covering the widest areas. I will present our latest efforts to chart the formation and evolution of the most massive galaxies in our universe, taking us back to the first 500 million years after the Big Bang. I hope you can join us this afternoon! Best, Leslie -- Leslie F. Brown, Ph.D. Emeriti - Physics, Astronomy & Geophysics Connecticut College New London, CT USA

I attended the SAS meeting last night and have the following questions: 1. It was discussed that the Messier Marathon alternate date was Friday - 4/25. That is the same night as the Lyme Land Trust Observing event. Do we want to move the date to the 26th? 2. Who has the PST Solar Scope? SAS has an event on Sat 4/26 and I thought I would bring it (not that I want to be the holder of all of the club's scopes ;) ) 3. On Sat 5/17 the SAS club, in cooperation with the Town of Madison is doing a public outreach event at Salt Meadow Park in Madison. It would be great if the club could assist by bringing scopes to this inaugural event. Thoughts????

This month's speaker features Physicist Sarah Bull of the Stamford Museum. She will be talking about a brand new Astronomy Center there.

(sovera:announce) SoVerA Monthly Meeting April 8th 2025 Not sure if I remembered to send this to the group or not. It was a very long weekend not just working at NEAF but the horrendous drive back and forth in the rain at night with heavy traffic. Fortunately, its was 2 hours at best. An hour and a half in the morning so that's favorable. Tonight's SoVerA meeting will have a talk on "The Edge." The expansion of an Infinite Universe. The speaker is Erik Schmitt who you may recall spoke at our January meeting. He's quite talented and a very good speaker. The Zoom link is below and begins at 7 PM ET tonight! John Sillasen Subject: (sovera:announce) SoVerA Monthly Meeting April 8th 2025 Please join SoVerA on Tuesday April 8th at 7:00PM Eastern for a presentation by Erik Schmitt. This meeting will be virtual-only via zoom at https://zoom.us/j/94691230307. This month's talk is entitled "The "Edge" of an Infinite Universe which is Expanding?" We will walk through a series of thought experiments and discussion intended to provide some tools to effectively grapple with the topic and answer common questions such as "What is the Universe expanding into", "If the Universe is infinite how is it getting bigger", and "Is there an edge?" Erik Schmitt is currently serving as the treasurer of SoVerA. He previously taught physics and astronomy and was the director of the Perkin Observatory. ____________________________________________________________ Southern Vermont Astronomy Group (SoVerA) _._,_._,_

Anybody else see it late last night? Looks brighter than predicted Mag 2. Mag 1?

I found this accessible pdf guide to the Messier Marathon by objects by the hour. It was posted on Facebook and I renamed to give them proper credit for doing the work. The file name is MessierMarathonGuidebyUnistellar.pdf /g/TAASCT/files/MessierMarathonGuidebyUnistellar.pdf The link to the file is above. If you find it inaccessible it's likely that you never created a personal password to access /g/taasct. You can easily do that just go to and login. Ask for a password reset or create a password and you'll follow the bouncing ball..it's easy. John Sillasen

The following items have been added to the Files area of the [email protected] group. /MessierMarathonGuidebyUnistellar.pdf By: John A. Sillasen <jasillasen@...> Description: This guide is from Unistellar and it describes imaging the objects plus what objects to view by the hour! It's not a long file but can be useful..

Title says it all. I’m canceling tonight at Propbusters and Ranger Russ and Jim Mazur have canceled tomorrow’s Hammonasset event. Good news: the moon will still partially block the sun tomorrow morning. Not sure if we’ll be able to see it though. Mark

Today's What's Up Webcast from Sky-Watcher USA is with an interview with a very enthusiastic and personable young lady from Kosovo, Pranvera Hyseni. She not only lead the activity to get a public observatory in Kosovo but also to get the funding and telescope to go in it. I had the pleasure of meeting her at Stellafane a bit ago.. very person and enthusiastic! Should be an enjoyable talk! I regret not publicizing the What's Up Webcast with Ann Druyan, widow of Carl Sagan and person responsible for the gold albums and their content that fly on Voyager to this day. It was one of the most memorable and inciteful talks I have ever heard. I hope you look for it and watch. She also wrote a sequel to Sagan's Contact in 2022 called Cosmos Possible Worlds. I have it in hard cover. John Cc: Sent: Fri, Mar 28, 2025 at 9:08 AM Subject: What’s Up Webcast. Everything astronomy every Friday.
