Comet C/2023 A3 Tsuchinshan-ATLAS survived perihelion to become a fine dusk object for northern hemisphere observers.
It was an amazing month for astronomy. Not only were we treated to an amazing second solar storm for 2024 that sent aurorae as far south as the Caribbean, but we had a fine naked eye comet: C/2023 A3 Tsuchinshan-ATLAS.

Sungrazer C/2024 S1 ATLAS broke apart at perihelion.
Alas, a ‘Great Halloween Comet’ was not to be. The Universe teased us just a bit this month, with the potential promise of a second naked eye comet in October: C/2024 S1 ATLAS. Discovered on the night of September 27th by the Asteroid Terrestrial Last-alert impact System (ATLAS) all-sky survey, this inbound comet was surprisingly bright and active for its relative distance from the Sun at the time of discovery. This gave the comet the potential to do what few sungrazers have done: survive a blisteringly close perihelion passage near the Sun.

With ‘Thousand Sails,’ China joins the race to fill up Low Earth Orbit with mega-satellite constellations.
It’s getting crowded up there in Low Earth orbit (LEO). By now, flocks of Starlinks have become a familiar sight, and the bane of astrophotographers as the ‘vermin of the skies.’ Now, several new competitors have joined the fray, with more waiting in the wings.

Unistellar’s new Odyssey Pro telescope offers access to deep-sky astrophotography in a small portable package.
Access to the night sky has never been simpler. The last half decade has seen a revolution in backyard astronomy, as ‘smartscopes’—telescopes controlled by smartphone applications—have come to the fore. These offer an easy entry into basic deep sky astrophotography even from bright urban skies, albeit at a higher price point versus traditional telescopes on the market. We’ve reviewed units from Vaonis and Unistellar before, as well as wrote commentary on the rise of the whole smartscope movement. Now, Unistellar has a new entry on the market in 2024: the Odyssey Pro.

Could this be the next great comet? To be sure, these words have been said lots of times before. In a clockwork sky, how comets will perform is always the great wildcard. Comets from Kohoutek to ISON have failed to live up to expectations, while others like W3 Lovejoy took us all by surprise. But a discovery this past weekend has message boards abuzz, as an incoming sungrazer could put on a show right around Halloween.

A remote annular solar eclipse bookends the final eclipse season for 2024.
The final eclipse of the year is almost upon us. If skies are clear, a few lucky observers and intrepid eclipse-chasers will get to witness the passage of the Moon in front of the Sun one last time on Wednesday, October 2nd during an annular solar eclipse.

Now is the time to catch Comet A3-Tsuchinshan-ATLAS at dawn.
The window is now open. If skies are clear, set your alarm heading into this weekend to see Comet C/2023 A3 Tsuchinshan-ATLAS at dawn. We’re already seeing great views of the comet this week from southern observers and astronauts aboard the International Space Station. The visibility window is now even creeping up to the southern tier latitudes of the contiguous United States (CONUS). If fortune favors us, the comet could hit an easy naked eye magnitude +2 by next week, and forward scattering could even boost this into negative magnitudes… the rare term ‘daytime comet’ is even getting kicked around a bit in cometwatching circles.

The Moon just brushes the umbral shadow of the Earth during Tuesday night’s partial lunar eclipse.
A shallow partial lunar eclipse is on tap for the night of September 17th/18th. The eclipse is a slight one to be sure, but will be noticeable as the northwestern limb of the Moon just slips past the dark inner umbral shadow of the Earth. The eclipse is just over 8% partial at its maximum, meaning the Full Moon will look a little ‘smushed’ on one side at mid-eclipse.

A new book looks at the latest scientific insights versus a key question in astronomy and space science.
It’s tough to answer a scientific question, with a just data point of one. How special are we, and how common (or rare) is the story of how life arose on the Earth in the grander drama of the cosmos?
A new book out this week entitled Is Earth Exceptional? The Quest for Cosmic Life by Mario Livio and Jack Szostak looks at the scientific state of answering this key question. The book offers a sweeping view of the nascent science of astrobiology, a multi-disciplinary field melding biology, chemistry, astronomy and more.

Three amazing recent asteroid finds show what’s possible in terms of astronomy online.
Practical astronomy is increasingly becoming an online affair. In 2023 we wrote about this trend, and highlighted how Russian observer and amateur astronomer Filipp Romanov used time on remote observatory networks to successfully discover two asteroids, which he named 623826 Alekseyvarkin and 623827 Nikandrilyich after his great-grandfathers. Now, Filipp has repeated this feat and pushed the limit of what’s possible online with the discovery of a trio of asteroids, including a rare near-Earth asteroid discovery found using a remote system.
