#astodon — Public Fediverse posts

New episode comes out tomorrow!

We'll be meeting a new (to us) historical figure in #american #astronomy & exploring the science of sunspots.

Anyone have a guess on which #astronomer we paired with this topic??

So apparently the hashtag #astodon is kind of unused, except for some typos and the occasional astronomy post (which is wrong imho, that should be called #astrodon).

You know what that hashtag would be perfect for? Dendrology. Because "Ast" is German for "branch".

Just a suggestion. 🙃

My first solo book presentation at a packed #Planetarium in #Bochum. Honestly, I was a bit nervous at first, since you never know how people react, but it went very well. I had a great time, got wonderful feedback and all available books were sold. Lots of questions afterwards. So, that was a good start for the book tour 😅

Distant galaxies reveal hidden effect from Big Bang: With these data, they observed a decrease in the radio emission which matches prediction from the supernovae electrons interacting with the Cosmic Microwave Background photons.

Something for the specialists perhaps, but nice to see evidence for this effect (we have been talking about for ages).

Eins der Dinge, die ich in meinem Buch erwähne, ist meine tolle persönlich Erfahrung mit Rai Weiss, der diese Woche verstorben ist:

Ich wünschte, ich müsste nicht die Änderungen einbauen, die nun anstehen - aber ich bin auch beeindruckt, dass heute früh direkt eine Mail von meinem Lektor im Postfach war, mit der Frage, ob wir die letzten Tage vor dem Druck noch dafür nutzen sollen, den Text entsprechend zu ändern :(

Die Welt ist ein bisschen ärmer geworden.

And in today’s who’s got two thumbs and didn’t pay attention during target framing, it’s my Sculptor Galaxy (aka the Silver Dollar aka NGC253) with globular cluster NGC288 right on the edge and not slightly over where they would’ve made a lovely pairing.

There was some thin cloud, so I can have a better go with better framing when the next set of rainy and cloudy nights finishes. In october or something.

Variations in the magnetic field at Jupiter’s so-called "Great Blue Spot" - a region of intense magnetic field along its equator first spotted in observations from NASA’s Juno spacecraft - are reported in a new study just published in Nature. This analysis may provide insights into the gas giant’s interior.

A search for dwarf galaxies in the Local Void, using data of the DESI Legacy Imaging Surveys

by Igor Karachentsev and co-authors

https://arxiv.org/abs/2312.04930

📷 Images of 12 new dwarf galaxies from DESI Legacy Imaging Surveys found in the Local Void region. Each image size is 2′ × 2′. North is to the top and East is to the left.

Trying to work out how/where to add a Mastodon verification link to a Jekyll site and not finding much from searches.

Any suggestions more than welcome

@AstroKatie Of course, Mastodon can’t be better than Twitter before Elon. That will take a few years, but it is good enough for now and the basic idea seems valid. (I would still like to retoot with comments though) #astodon

This week we published the awesome first detection of the polarised radio emission from the intergalactic space in between 600,000 pairs of matter halos, which convinced us to have conclusively detected the shocked cosmic web.

Why do we think it is such a big deal?

The Curiosity rover has released its first cache of rock samples for future return to Earth. This release is an insurance policy. It ensures that if the rover suffered a fatal malfunction in the near future that at least some samples it collected will not be stuck inside the rover. https://go.nasa.gov/3WzZ5qF #mars #astodon
