NASA Scientist with the LROC, Robert Wagner, and no, not the actor, has discovered the newest and largest crater in our Solar System recently. The crater is named officially McGetchin, after Tom McGetchin, a pioneering lunar scientist. It is estimated that the crater formed between April 11th and May 22nd 2024. The cause was most likely a comet or asteroid the size of a three story building that impacted the surface!
The newly formed crater is 728 feet wide, spanning the length of almost two football fied. It is 141 feet deep
As always I have a full article and images over at Eadsy Astronomy LINK.
Also, on this object I do have a FULL article on it on Eadsy Astronomy LINK and I tie in that you can image or visually observe this object for youself. I think that makes it rather cool to tie in what we learn about it to our own imaging or observing!
ALMA Watches a Massive Binary Star System Develop in Real Time!
The telescope ALMA was used by astronomers to caputure one of the most detailed images of a massive binary star system being born!
They tracked the motions of these two stars for the last 8 years and found that the pair follow a highly stretched out orbit and are surrounded by strongly tilted disks. This suggest that the the two stars didn't form together from a single spinning disk of material as is often assumed. Instead they formed independent of each otehr and entered into their binary relationship during a close and chance gravational encounter.
I have a full article if you want to read this and a link to the orginial article over at Eadsy Astronomy LINK.
Here is the Eadsy Astronomy Newsletter for September 16th to September 27th, 2026. I am moving to do two a month now, a lunar and double star with comets focus for the waxing Moon period. Then the second will be a waning gibbous to New Moon period for a focus on Deep Sky Observing and imaging each month .
Here I give 2 eye candy targets for lunar objects and double stars each night and 1 challenging object for the Moon and for Double Stars. I share some eye candy deep sky objects with an emphasis on open clusters and bright Messier's. I also discuss in detail the 3 comets that we have that we can still image or observe right now!
I also review the planetary objects in our sky from bright Venus (which you can see low on the western sky in the image I took on September 14th from the West Desert of Utah with a waxing Crescent Moon chasing it) at around mag -4.1 or so to Saturn and Neptune which by 10pm or 11pm here in Utah are position great for observing during this period. Finally Mars and Jupiter are up in the early morning.
Because I have a variety of objects up in the early morning, on the double stars and deep sky objects I am going to include some of the winter objects that are now up in the early morning sky!
Also, on the Google Doc I've updated it to where there are drop downs so you can focus on day, challenging or eye candy objects etc. I hope the drop downs help you to use the newsletter a little bit easier.
To see and/or get a copy of the Newsletter, head over to Eadsy Astronomy at this LINK. If you find value, please consider joining our community there as you get first notice of my posts, docs and other information as I always post there first. Materials are free but if you find value in this, and want to make a donation or become a contributing member you can at the $3.00 or $5.00 a month level. Donations cover some of the apps, materials and other items I use to bring this to you. I appreciate those that are contributing members!
Went observing last night and the clouds went away after sunset! Wonderful night and can I say that SN 2026 aaiv in NGC 7331 visually is AMAZING in my 17.5"! Look for my report in the next couple of days over at Eadsy Astronomy!
just show my recap of my observing from September 7th, 2026 near Ashton Idaho (north of there) in SQM skies of 21.8 to 21.9. I show the Milky Way and my sketches and SeeStar Images from two nights (September 7th and September 9th, 2026 for the SeeStar).
To read and watch all the material head over to Eadsy Astronomy and please join our community there to get first notice and my indepth articles on my observing and other information there! LINK.
The unbarred spiral galaxy NGC 7331 in Pegasus—often referred to as "the Milky Way’s twin"—has offered observers a rare occurrence. Between July 2025 and September 2026, the galaxy hosted two consecutive Type Ia supernovae.
Let me share that this is significantly rare. Extragalactic supernovae typically erupt once per galaxy every few centuries, making back-to-back "supernova siblings" within ~14 months in a single target a fascinating cosmic coincidence.

For my full article head over to Eadsy Astronomy at this LINK and to see images of last year's and this year's supernova there and my sketches of NGC 7331.
