My first try for Saturn since last year. It took a while to set up my scope for this. I'm feeling very rusty! The rings are narrowing with their South face tilted towards us; they'll be nearly edge on around the end of November. It feels good to be doing planetary imaging again 🙂 🔭

There's something about a crescent moon that rivals other phases. They're so dramatic. I rendered this one as a "mineral moon," revealing its mineral deposit colors. My Portfolio: portfolio.pixelfed.social/JoeGarrity #astrophotography #astronomy #naturephotography #nature #moon #lunar #photography

I captured the newly discovered comet C/2025 A6 Lemmon. It was first observed earlier this year by Mount Lemmon Observatory in Arizona. My Portfolio: portfolio.pixelfed.social/JoeGarrity #astrophotography #astronomy #naturephotography #nature #longexposure #comet #photography

Saturne ce matin depuis mon balcon à Paris. Seeing exceptionnel. C'est juste une acquisitions traitée vite fait sur le pouce.

À lire : La mission Proba-3 de l'ESA a dévoilé ses 1ères images de la couronne solaire. Les 2 satellites de la mission, qui volent en formation avec une précision de l'ordre du millimètre, ont réussi à créer leur 1ère « éclipse solaire totale artificielle » en orbite... www.esa.int/Space_in_Mem...

Une éclipse de soleil artificielle ! La sonde Proba-3 est faite de 2 satellites qui volent en formation: l'un a un disque opaque et se place 150m devant l'autre qui prend la photo. En se positionnant à 1 cm près l'un de l'autre, ils arrivent à créer cette éclipse de soleil.

This new study, from Dylan Grigg at Curtin University, is not the first to study the impacts of Starlink on #RadioAstronomy, but is the largest of its kind and quantifies how this type of radio frequency interference - that comes from above - will impact the mega-science SKA project. 📸 DISR 📡🔭

Radio frequency interference from Starlink not only spans the narrowband intended emissions but also broadband unintended emissions, coming from propulsion and avionics. This RFI is unregulated and affects key science goals. Starlink can appear in ~30% of all sky images. 📸 Grigg et al. 2025 📡🔭

An Emerging Risk To #RadioAstronomy 📡 Using a prototype SKA-Low instrument, a new analysis from @icrar.bsky.social has detected Starlink signals leaking into protected radio bands. @cosmicrami.com writes about this new study. www.spaceaustralia.com/news/emergin... 📸 Astro_Work 🔭 #SpaceAustralia

Here is the probability of seeing the aurora tonight in Europe (22:00 UTC to 00:00 CEST). The chances are low, but it could be a good challenge if you're really motivated! There is a better chance of capturing it on camera... if the activity lasts long enough into the night! 🌘

I am very sad to report that Fred Espenak has died. Astrophysicist and renowned Solar Eclipse chaser/observer. Famed for his guide to Lunar and Solar eclipses. Also my friend on Facebook for many a Moon. My condolences to his family and friends. 🔭 🧪
